Bus Transfer Paradigm Shifts in Plant Breeding: Automated Phenotyping Combined with Modern Genetics Type of presentation: oral Authors: Professor Arjen van Tunen, Keygene, Wageningen, NL Presenter: Arjen van Tunen Keygene NV PO Box 216 6700 AE Wageningen NL +31 317 466866 [email protected] Abstract: During the last 50 years plant breeding has resulting in gigantic improvements of crops in terms of yield, quality, resistances and appearance of our agricultural products. However the traditional methods are now reaching their limits. At the same time society needs large improvements of our crops to meet the current and future demands for high quality food, feed fiber, fuel, flowers and fun agricultural products. In this presentation paradigm shifts are elucidated that will lead to to the desired improved and innovative crop varieties. First, large scale genomics information is available and used for an increasing number of crops. Second, besides Genetic Modification alternative molecular genetic methods are under development that allow fast Molecular Breeding and Molecular Mutagenesis. Third, new automated and robotized phenotyping methods are now being implemented enabling the establishments of correlations of genetic variation with traits of socio economic importance and thereby enabling a new and integrated way of molecular plant breeding. In a number of practical examples it will be shown that genomics in combination with new phenotyping approaches leads to fast and directed ways of genetic improvements of our crops for the future. 11 High Throughput Plant Phenotyping – a Boost for Genomics in the 21st Century Type of presentation: oral Authors: Matthias Eberius, Dirk Vandenhirtz, Jörg Vandenhirtz, LemnaTec Germany Presenter: Dr. Joerg Vandenhirtz LemnaTec 18 Schumanstr. 52146 Wuerselen DE +49 2405 4126-12 [email protected] Abstract: Due to the development of highly automated genetic analysis, plant genomics has immensely enlarged our understanding of the genetic structure of plants over the last two decades. The fast evolving need to identify interactions between genes and environmental factors (biotic and abiotic) that brings about a certain plant phenome made it necessary to develop quantitative, reproducible and highly automated plant phenotyping systems for large plant numbers. Phenotyping systems such as these have to integrate reproducible plant management (randomization, watering) and comprehensive imaging of root and shoot far beyond human vision (visible light, fluorescence, near infrared, infrared, X-rays, THz) as well additional chemical analysis methods. Immediate and automated image analysis of the stored images and further data transformation using plant shape and plant growth models are the important intermediate steps before undertaking statistical data analysis of the phenotyping results to characterize plant phenotypes quantitatively. Such quantitative data contributes in a decisive way to the further analysis of gene functions (tilling, QTL etc.), especially under fluctuating or stress-induced environmental conditions with a special focus on complex traits like yield or drought tolerance. This presentation will provide a survey on phenotyping technology and the close interaction between phenotyping technologies, modeling approaches and the new opportunities of fast and automated high-throughput genomics. 12 Prospects of High Throughput Phenotyping for Climate Change Research In India Type of presentation: oral Authors: B.Venkateswarlu Presenter Dr. Bandi Venkateswarlu Central Research Institute for Dryland Agriculture Santoshnagar Saidabad PO 500 059 Hyderabad IN +91-40-24530177; 09652988265 (Mobile) [email protected] Abstract: Climate change and climate variability have become major areas of concern for agricultural growth in India. Multiple abiotic stresses like droughts, floods, chilling injury and heat wave are becoming more common with increasing seasonal climate variability with significant impact on crop and livestock production. The Government of India has initiated a major national effort on climate resilient agriculture covering research and technology dissemination. In 2011, a major national scheme, viz., National Initiative on Climate Resilient Agriculture (NICRA) has been launched. This scheme has several components, one of which is the phenotyping of crop germplasm for multiple abiotic stresses like drought, salinity, heat stress, cold injury and water logging. Research infrastructure is being developed at major national research institutes involved irrigated crops, rainfed crops, horticulture and fisheries. Both laboratory and field phenotyping facilities are being set up in four major locations in India. The major aim of these facilities is to undertake rapid screening of available germplasm from the gene banks and also the current collections being made from climate hot spots in India. The presentation gives details of the crops being covered under the climate resilient agriculture project in India, institutions involved and abiotic stresses short listed for Germplasm screening through phenotyping. 13 Plant Phenotyping : Picture this with machine vision Type of presentation: oral Authors: Rob Lind Presenter: Dr. Rob Lind Syngenta Biological Sciences, Jealott's Hill International Research Centre Bracknell RG42 6EY Berkshire GB +44 (0)1344 414466 [email protected] Abstract: Plant phenotyping, which connects attributes of plant anatomy, physiology and performance back to their genetic origins and xenobiotic influences, is crucial for plant breeding. Traditional human observation is tarred with its subjective nature, drift over time, differences between observers and its often qualitative output. Machine vision offers solutions to these problems and in addition benefits from a fully quantitative output, abilities to look beyond human spectral perception, and measure parameters that are more challenging to the human observer. Image analysis coupled with high through-put automated systems is revolutionising plant phenotyping to remove a previous bottle neck to enable the rapid selection of favourable traits for plant breeders. This talk will focus on different plant structures, namely roots, aerial stems and leaves, fruit and seed, and how the software and hardware surrounding machine vision can be used to measure their respective phenotype parameters. A key to the success of image analysis for plant phenotyping within Syngenta has been to create a network of interdisciplinarv colleagues bound together by a common interest in imaging technologies and processing. 14 High-throughput phenotyping - Taking crop biotechnology to the next level Type of presentation: oral Authors: Michael H. Malone, Jasenka Benac, Emily Grasso, Hyundae Hong, Dan Riggsbee, and Keith Koutsky Presenter: Dr. Michael Malone Monsanto Company 110 TW Alexander Dr. PO Box 110604 27709 Research Triangle Park NC US 919-406-5738 [email protected] Abstract: Innovative technologies are required to meet the agricultural needs of a growing world population, which is estimated to reach 9 billion by 2050. Monsanto is committed to meeting these needs by improving the lives of farmers. Our goal is to use breeding, biotechnology and improved farming practices to develop crops that produce more yield while conserving natural resources. A key step in this process lies in identifying plants that possess traits that enable farmers to produce more yield with less water and fertilizer. To speed the identification of plants that have the traits farmers need, we have developed a high-throughput phenotyping facility that fuses automated plant handling and imaging technology. This facility allows us to quantify growth and whole plant physiology in precisely controlled environments. Here we present the opportunities and challenges inherent in high-throughput screening of biological systems, particularly as they apply to plant biotechnology. 15 Application of Hyperspectral Imaging in Precision Phenotyping Systems Type of presentation: oral Authors: Jonathan Lightner Presenter: Dr. Jonathan Lightner Pioneer Hi-Bred Intl 7250 NW 62nd Ave Johnston IA IA US 515-535-3978 [email protected] Abstract: Not available. 16 Use of The Plant Accelerator® for high-throughput phenotyping Type of presentation: oral Authors: Mark Crowe, Bettina Berger, Helli Meinecke and Mark Tester The Plant Accelerator, University of Adelaide Waite Campus, Hartley Grove, Urrbrae SA 5064, Australia Presenter: Dr. Mark Crowe The Plant Accelerator® University of Adelaide, Waite Campus, Bldg 32 Hartley Grove 5064 Urrbrae AU +61 (0)4 3433 1588 [email protected] Abstract: The Plant Accelerator® is a purpose-built plant phenotyping facility in Adelaide, Australia. With over 2,300m2 of floor space across 38 greenhouses, four of which are SmarthousesTM equipped with LemnaTec Scanalyzer 3D systems capable of accommodating nearly 2,400 plants, it is one of the largest publicly-accessible image-based plant phenotyping facilities in the world. The Plant Accelerator is a dedicated service facility, undertaking projects for plant scientists, whatever their research targets or geographical location. Nevertheless, we have particular expertise in cereal projects, especially in the areas of drought and salinity tolerance – characteristics of particular importance in the Australian environment. Both drought and salinity tolerance are complex multifactorial phenotypes, subject to many Genotype x Environment interactions. The consequent low heritability of these traits results in difficulties validating quantitative trait loci across different trials, and so restricts the ability of phenotyping research projects to assist in the breeding of new, more tolerant, varieties. The facilities at centres such as The Plant Accelerator are now helping researchers dissect these phenotypes into simpler and more robust traits, with the increased likelihood of identifying either causative genes or reliable genetic markers. The Plant Accelerator is now being used to study previously intractable physiological processes, and I will describe some of the outcomes of a variety of such projects on salinity and drought tolerance that have been carried out at the Accelerator. I will also outline some of the ‘tricks of the trade’ that we have identified to allow us to carry out these projects more successfully. Finally, I will discuss our work on the description of phenotypes that were conventionally only measurable using destructive testing so that we can now achieve accurate estimates of these phenotypes based on imaging data alone. 17 Development of High Throughput Plant Phenotyping Facilities in Aberystywth Type of presentation: oral Authors: Catherine Howarth, Alan Gay, Tom Bartlett*, John Draper, John Doonan National Plant Phenomics Centre, IBERS, Gogerddan, Aberystwyth University, SY23 3EB, UK * See3D Ltd, Aberystwyth University Presenter: Dr. Catherine Howarth Aberystwyth University IBERS Gogerddan Aberystwyth SY23 3EB GB 1970823107 [email protected] Abstract: There is a need to develop high throughput plant phenomics to bridge the phenotypegenotype gap that will lead to the improvements in crop performance necessary to feed the growing world population. The facility under development at Aberystwyth will be based around automated non-destructive image analysis using a Scanalyzer 3-D HTS system developed by LemnaTec running in a new glasshouse complex. A central advantage of the approach is that it is inherently non-destructive, allowing repeated measurements to be made on individual plants in a pre-programmed sequence through time with minimal operator intervention. The system is flexible, designed to cope with small plants such as forage grasses, forage legumes, Brachypodium and Arabidopsis, and also with larger plants such as oats, wheat, barley, maize and Miscanthus. The plant phenomics facility will be closely linked to both chemical phenotyping and genotyping facilities in Aberystwyth and integrates with field trials and public good plant breeding. Use of the facility will accelerate the selection of appropriate germplasm for breeding varieties which will perform robustly under the conditions predicted for the UK and beyond in the future. Furthermore, it will provide a focus for trans-disciplinary research to facilitate the discovery of the genetic and environmental bases for variation in complex traits that underpin the major global challenges for food and energy security, water utilization and adaptation to a changing climate. 18 Towards innovative cropping systems: development of High Throughput Phenotyping of plant biotic interactions. Type of presentation: oral Authors: Christophe SALON1,2, Christian JEUDY1, Céline BERNARD2, 1UMR Legumes Genetics and Ecophysiology (LEG), INRA, 17 rue Sully, BP86510 Dijon Cedex, France 2Experimental Unit Greenhouse and Phenotyping platform, INRA, 17 rue Sully, BP86510 Dijon Cedex, France Presenter: Dr. Christophe SALON INRA UMR LEG and UE SEDE BP 86510 17 rue Sully, 21065 Dijon FR 0380693238 [email protected] Abstract: The design modularity of the greenhouses and climatic chambers allows various growth conditions for plant in order to mimic most of the environmental scenarios in the context of climate change. Climatic chambers are either equipped with conveyors in line with phenotyping cabins, used for large biological units and rhizotrons or devoted to the “small biological units” (ie seeds, plantlets, microbiological petri dishes) phenotyped in a cabinet (called “HTS”) where mobile cameras screen the culture zone. This HTS and its climatic chambers allow to phenotype, in addition to our 1800 plants/1000 rhizotrons phenotyped in greenhouses, thousands of seeds and more than four hundred plantlets daily. A High Throughput Plant Phenotyping Platform (PPHD), located in Dijon (France), is under final stages of construction. It will provide the opportunity to apply well-characterized biotic and abiotic constraints to several hundreds of genotypes (thousands of plants) and to accurately measure a series of functional traits. Although it can also analyze plant architecture and plant/plant interactions (ie crops versus weeds competition for resource access and the consequence in terms of plant development), the PPHD is specifically devoted to plant/micro organisms interactions. It allows establishing/testing causal relationships between genetic markers and phenotypes related to plant performance under a range of environmental conditions, including those forecasted by models of climate change. PPHD is constituted of a large building with S2 modular greenhouses and climatic chambers. These are equipped with conveyors belts to homogenize plant growth conditions and automatically bring plant units to the phenotyping cabinets. Six additional S2 greenhouses are used for growing plants (either in pots or rhizotrons) when they do not need to be phenotyped during their whole growth cycle. Phenotyping is based on image analysis (visible 19 light, near infrared and fluorescence) which allows characterizing non destructively and automatically i) a large variety of plant species and specifically designed high throughput rhizotrons ii) seeds or microorganisms, plantlets. The understanding of the genetic determinisms involved in plant/plant and plant/microorganisms interactions and the progress in selection/varietal innovation that will follow offer a unique opportunity, today still underexploited, for designing sustainable agriculture with large eco systemic services. 20 VEGI: Value-directed Evolutionary Genomics Initiative Type of presentation: oral Authors: Thomas Bureau Presenter: Professor Thomas Bureau McGill University Department of Biology 1205 Dr. Penfield Avenue H2W2L3 Montreal CA 1-514-398-6472 [email protected] Abstract: In general, genomics has been traditionally centered around the notion of identifying “host” genes that can be gleaned from genomic sequence and the subsequent high throughput characterization at the level of their gene expression and/or, if any, protein products. But host genes make up only a small percentage of many eukaryotic, including plant, genomes. Instead host genes are surrounded by a vast ocean of so-called non-coding DNA. Long thought to be of little functional significance and not amenable to characterization by traditional genomics approaches, recent evidence has surfaced indicating that the noncoding DNA harbours islands of sequences that may have profound functional significance. We argue that this large and uncharted region of plant genomes is rich with potential sequences of developmental significance and, importantly, agronomic application. Furthermore, our proposed research project will allow the rapid harvest of the “low hanging fruit” entering a pipeline for experimental and utility validation. We intend to reveal and characterize these functional non-coding DNA sequences by employing a strategy that combines comparative, population and functional genomics approaches. This strategy involves not only computational or bioinformatics approaches but also genome sequencing, expression profiling, gene disruption via insertion mutagenesis and RNA interference, and detailed phenotype characterization. Key to our strategy is using comparative and population genomics methodologies that uncover non-coding DNA sequences that evolve under negative (purifying) or positive (adaptive) selection. Whereas negative selection indicates sequences that are functionally conserved, positive selection indicates sequences that have novel advantageous function. The other key component of our strategy is extensive experimental characterization of triaged targets including the exploitation of a newly installed automated phenomics platform. In consultation with our agricultural economics team members and scientific advisory board candidate targets will be selected that have the greatest potential for agronomic impact and, therefore, be candidates to enter our processing pipeline. 21 A high throughput early screening platform for selection of phosphorus efficient maize genotypes Type of presentation: oral Authors: Sylvia Morais de Sousa, Randy T. Clark, Flávia Ferreira Mendes, Antonio Carlos de Oliveira, Leon V. Kochian, Maria José Vilaça de Vasconcelos, Newton Carneiro Portilho, Sidney Netto Parentoni, Cláudia Teixeira Guimarães, Jurandir Vieira Magalhães. Presenter: Dr. Sylvia Morais de Sousa EMBRAPA Maize and Sorghum Rod. Mg 424 Km 45 35701-970 Sete Lagoas BR +55313027-1293 [email protected] Abstract: Phosphorus (P) is an essential nutrient to the plants and is acquired from the rhizosphere solution as inorganic phosphate (Pi), primarily in the form of H2PO-4. In tropical soils, Pi concentration in the soil solution is often low and its diffusion strongly limited by fixation to aluminum and iron oxides in the clay fraction. Hence, P is one of the least available mineral particularly in highly weathered, tropical soils, limiting substantially plant growth. An interesting approach to circumvent P deficiency in tropical areas is to explore the genetic diversity available in plants to breed cultivars more efficient in P acquisition. This study aimed to standardize the growth conditions in nutrient solution and to define phenotypic traits for a high throughput early screening platform in order to select maize genotypes more efficient in P acquisition. Field phenotyping results under low and high P conditions showed that genotype L3 has a higher P acquisition efficiency than L22. These two contrasting genotypes were used for nutrient solution phenotyping standardization. These results indicated that morphological characteristics as P content in shoots, root:shoot dry weight, root volume and fine roots (1-2 mm) after 12 days of growth under 2.5 μM P in Magnavaca´s solution seemed to be the best parameter for early selection of maize genotypes under P deficiency. Also an imaging system was improved, permitting a faster quantification of the entire root system. Expression profile suggested that Rtcs, Rth3 and Bk2 would be good candidate genes for additional screening criteria of P efficient maize genotypes. The genetic studies showed that most of the root characteristics had a high heritability and a low coefficient of variation. Moreover, a high correlation was found among root morphology traits, whereas no correlation was detected between hybrids and inbred lines for those traits. Thus, these results are essential to proceed an early selection for P efficiency in maize and to support advanced molecular and physiological studies, culminating on the generation of maize cultivars more efficient in fertilizers use. 22 Overcoming the phenotyping gap - experiences with the LemnaTecScanalyzer 3D platform investigating drought tolerance in barley Type of presentation: oral Authors: Kerstin Neumann, Nils Stein, Andreas Graner, Christian Klukas, Alexander Entzian, Benjamin Kilian Presenter: Kerstin Neumann IPK Gatersleben Corrensstrasse 3 06466 Gatersleben DE +49394825816 [email protected] Abstract: The LemnaTec-Scanalyzer 3D system in the IPK Gatersleben was established in 2008 and was one of the first LemnaTec-platforms in the public domain. Since then it is used for phenotyping drought tolerance of different barley cultivars. Plants are phenotyped fully automated with three different camera systems using I) visible light, II) fluorescence, and III) near infrared. In the beginning, several replications of a vegetative drought stress experiment were conducted using parents of a DH-population Morex and Barke, for testing the reproducibility of phenotypic values with the Scanalyzer system and gaining experiences. Since autumn 2010, the IPK is involved in the CROP.SENSe.net project and drought stress is applied to a barley core set of eight old and eight modern german spring barley cultivars. The set shows a good phenotypic diversity in growth under control and drought stress conditions. In future, a larger set of a worldwide spring barley collection will be phenotyped for a genome-wide association study. 23 Measuring shade-induced movements of Arabidopsis leaves using the Scanalyzer HTS – a novel phenotyping approach Type of presentation: oral Authors: Tino Dornbusch, Christian Fankhauser Presenter: Dr. Tino Dornbusch University of Lausanne Centre for Integrative Genomics Genopode building 1015 Lausanne CH ++41 21 692 3942 [email protected] Abstract: Most higher plants are able to position their leaves relative to the light source in order to optimize light interception for photosynthesis. In dense canopies, plants usually shade each other leading to an adaptation of their architecture, which is commonly denoted as the shade avoidance syndrome (SAS). Plants forming a rosette during their juvenile growth phase, such as Arabidopsis thaliana, respond with an upward movement of leaves (hyponasty) and increased petiole elongation upon being shaded. Moreover, the circadian clock gates these growth responses, leaves being more horizontal in the morning, reaching a more vertical position in the evening and returning to a horizontal inclination in the morning. Measurements of petiole length and angle, as important SAS traits in Arabidopsis, have usually involved photogrammetry or hand-operated devices, rendering those techniques unsuitable for high-throughput screenings. Here, we propose to use a custom-built version of the Scanalyzer HTS (Lemnatec GmbH, Würselen, Germany) to record time-lapse laser scanner images of Arabidopsis rosettes and measure their circadian leaf movements. Shade conditions (low R/FR) in the Scanalyzer HTS are mimicked using a FR diode array. Height-scaled images (output of laser scanning) are recorded each hour during a period of 48-72 hours. The image stack is subsequently processed as summarized hereafter: i) Conversion of height-scaled laser scanner images to 3D point clouds ii) Segmentation of point clouds to relate a sub-set of points to individual plants iii) Selection of the basal plant point P0 (geometric origin of leaves) iv) Selection of the blade-petiole intersection points PL v) Fitting of a parametric surface that superimposes best with the point cloud using the selected points P0 and PL 24 As a result, surfaces of selected individual leaves are depicted as parametric surfaces (polygon meshes), which in turn are computed using a 3D leaf model. The model parameters petiole angle and length are the SAS traits we are interested to measure. We here present our novel phenotyping approach using the Scanalyzer HTS, demonstrate its robustness and show its applicability on data sets obtained from shade avoidance experiments with Arabidopsis using a range of genotypes. 25 Phenotyping of plant material at Wageningen UR Type of presentation: oral Authors: Gerie Van der Heijden, Jochen Hemming, Henk Jalink, Jaap Kokorian, Gerard van der Linden, Gerrit Polder, Rick van de Zedde Presenter: Dr. Gerie van der Heijden Wageningen UR Droevendaalsesteeg 1 6708 PB Wageningen NL +31 317 480750 [email protected] Abstract: Using image analysis to measure plants for breeding and other plant research purposes has a long tradition within Wageningen UR. It includes spectroscopic/hyperspectral imaging, 3D imaging and chlorophyll fluorescence. In this overview we will show image analysis applications of plants, ranging from seeds and seedlings to growing plants, flowers and fruits, including disease detection. 26 Medium-throughput phenotyping of individual Lolium perenne plants under field conditions: an easy and low-cost procedure Type of presentation: oral Authors: Lootens P.(1), Ruttink T.(1), Rohde A.(1), Carré S.(2), Combes D.(2), Barre Ph.(2), Roldán-Ruiz I.(1) Presenter: Dr. Peter Lootens ILVO Caritasstraat 21 9090 MELLE BE +32 9 272 29 00 [email protected] Abstract: Corresponding author: [email protected] Association and QTL mapping studies in agricultural crops require phenotypic characterization of large, replicated collections of plants. The phenotyping is done under growing conditions similar to those in the field. We have developed low-cost image capture and analysis procedures to characterize large collections (about 2000 individuals) of L. perenne plants. L. perenne, an important forage grass of temperate regions, can be planted in monocultures or in mixed stands (grazed or mown). Biomass yield and persistence are important breeding goals. We described the phenotypic diversity of architectural characteristics of a L. perenne association mapping population (including wild accessions, breeding material and commercial cultivars). To estimate growth and regrowth capacity, we used a mowing regime that simulated pasture exploitation for each genotype at two locations (Belgium, France) over two seasons. Using parameters derived from top and side-view images, we described plant volume, habitus and geometry in ways that single manual measurements of plant height or diameter alone cannot. Time series at either low resolution (bi-monthly intervals to capture ground coverage potential) or high resolution (weekly intervals to capture leaf elongation), helped us design dedicated analysis of growth dynamics. Image analysis assessments were compared with classical manual measurements such as plant height, tiller number and biomass yield. The images led us to highly informative parameters for describing plant architecture and growth potential. We discuss how we overcome technical problems of taking images under non-standardized conditions, the image-analysis procedures and the correlation between extracted parameters and manual measurements. 27 High-throughput phenotyping technology for maize roots Type of presentation: oral Authors: Martin O Bohn and Tony E Grift Presenter: Dr. Martin O Bohn University of Illinois at Urbana-Champaign 1102 S Goodwin Avenue 61801 Urbana IL US 217 244 2536 [email protected] Abstract: This presentation describes the development of high-throughput measurement techniques allowing acquisition of phenotypical data describing maize roots. One of a maize root’s traits is the level of complexity, which was expressed in a Fractal Dimension (FD) calculated from root images. Another important trait is the Root Top Angle (RTA) that was measured using a new machine vision algorithm. The measurement system consisted of a semi-automated imaging box that provided a highly diffuse lighting scene and allowing imaging of up to 800 roots per day. The measurement techniques were evaluated using roots recovered from a large set of recombinant inbred lines (RILs) derived from two crosses between maize inbreds. The used parental inbreds are known to have different root characteristics and their progeny are expected to show segregation for root traits. Since for the measurement of root traits were non-existent, no comparisons to these standard protocols could be made. Nevertheless, the data showed that the techniques were capable of confirming significant differences in FD among parental inbreds and their progeny, as well as measuring variations in RTA that are known for the inbreds and their crosses. In addition, first hypotheses about the inheritance of root complexity (as expressed in the FD) and RTA in maize were derived and tested: initial evidence showed that root complexity is a phenotype probably determined by a multitude of genes with small effects. 28 High-throughput analysis of root system architecture in gel-based imaging system Type of presentation: oral Authors: Jenn To, Jinming Zhu, Paul Ingram, Ian Davis, Philip Benfey and Tedd Elich Presenter: Dr. Jennifer To GrassRoots Biotechnology 302 E. Pettigrew St 27701 Durham NC US 919.747.7410 [email protected] Abstract: Root systems in land plants are required for physical anchorage, nutrient acquisition and interactions with the soil biome. Signaling networks between the root and shoot regulate developmental and metabolic pathways to coordinate plant growth. The spatial configuration of different types and ages of roots in a plant is described as root system architecture (RSA). RSA traits are highly plastic and facilitate adaptation to different environmental conditions. Genetic variations in RSA can enhance agronomic traits in crops and have also been implicated in soil organic carbon content. RSA traits present major opportunities for enhancing crop yield, nutrient efficiency and stress tolerance, as well as agricultural sustainability. However, high throughput characterization of RSA traits has lagged behind that of above ground traits due to the difficulty of below ground imaging and the complexities of soil composition. Recently, multiple groups have reported advances in root phenotyping methods. Our group has implemented a cost-effective and sensitive gel imaging system for non-destructive characterization of RSA under controlled conditions. The three dimensional structure of the root system is captured over a series of 2D images collected in a full 360 rotation. This system has been adapted for analyzing RSA along a developmental series in a variety of plant species, including rice, maize, switchgrass, sorghum and model grasses. In the monocot model Brachypodium, this multi-parameter analysis can accurately classify inbred lines and indicates strong genetic effects on nutrientdependent responses. Characterization of RSA under differential nutrient availability in Brachypodium recombinant inbred lines for QTL analysis is ongoing. Applications of this phenotyping technology for agricultural and biofuel crop improvement will be discussed. 29 Towards 4D space and time models of plant root development Type of presentation: oral Authors: Thorsten Schmidt1, Taras Pasternak2, Dorothée Aubry2, Alexander Dovzhenko2,3, William Teale2, Hans Burkhardt1,3, Olaf Ronneberger1,3, Klaus Palme2,3,4,5 1 Institute of Computer Science, Chair for Pattern Recognition and Image Processing, AlbertLudwigs-Universität Freiburg, Georges-Köhler-Allee 52, 79110 Freiburg, Germany 2 Institute of Biology II, Faculty for Biology, Albert-Ludwigs-Universität Freiburg, Schänzlestraße 1, 79104 Freiburg, Germany 3 bioss – Center for Biological Signaling Studies, Albert-Ludwigs-Universität Freiburg, Albertstraße 19, 79104 Freiburg, Germany 4 Frias – Freiburg Institute for Advanced Studies, Albert-Ludwigs-Universität Freiburg, Albertstraße 19, 79104 Freiburg, Germany 5 FRISYS, Faculty for Biology, Albert-Ludwigs-Universität Freiburg, Albertstraße 19, 79104 Freiburg, Germany Presenter Professor Klaus Palme University of Freiburg Institute of Biology II / Molecular Plant Physiology Schaenzlestr. 1 79104 Freiburg DE 0049 761 203 2658 [email protected] Abstract: Improvements to crops have been mainly based on biomass and seed yield and, accordingly, have focused on the aerial portion of the plant. However, the root system is also indispensable for plant function. Due to its structural and morphological complexity, the developing root system has been largely neglected by plant breeders. Shaping the root system to maximize food production is further complicated by technical limitations in quantitatively measuring roots. This is due to (1) the difficulty in non-destructively quantifying position and performance of root structures below the ground, (2) the lack of tools to assess automatically and quantitatively the complex root systems of plant species in a standardized way, (3) the need to integrate large statistically relevant data sets into a general root growth model to accurately model root development in cases where not the whole root system is visible, and (4) to predict growth behavior under a wide range of conditions. To achieve a detailed functional and quantitative understanding of root systems, specific cellular features must be quantified in the three-dimensional (3D) context of cells and the root organ. We have developed the intrinsic Root Coordinate System (iRoCS) as a reference model for the Arabidopsis thaliana root. An associated automated image processing pipeline 30 annotates cells according to their location, type, and division status. iRoCS enables the direct quantitative comparison between roots at single cell resolution, and is able to incorporate any recognizable feature. To demonstrate the power of the technique, we measured the capacity of changing patterns of auxin flux within the RAM to effect subtle changes in cell division patterns. Perspective and applications of this novel approach will be shown. 31 KeyTrack Root Phenotyping - At the Root of Development Type of presentation: oral Authors: Anker Sørensen, Marco van Schriek, KeyGene, Wageningen, NL Presenter: Dr. Anker Sørensen Keygene N.V. Agro Business Park 90 6708 PW Wageningen NL +31317466866 [email protected] Abstract: Plant roots are economically very relevant since the distribution pattern of the root system in the soil determines the zone of water and nutrient availability to plants and differences in root and root development is related to crop yields and abilities to escape drought and soilborne diseases. The KeyTrack system allows for efficient execution of root research in a high throughput manner and is a robust phenotyping platform in a greenhouse setup. The phenotyping is based on imaging technology and uses the potential of a track that moves all plants fully automated through the greenhouse compartment and scanning areas. The plants grow in individual containers and are photographed at pre-set points in time and from different angles. The research presented encompasses the creation of an automated root phenotyping protocol and image analysis pipeline. The material used for this research is the tomato LA716 S. pennellii introgression line library created by prof. Dani Zamir. The research described merges the phenotypic data generated with genotypic knowledge, to feed lead discovery and root development in tomato. 32 Studying drought tolerance in Populus tremula (L.) Type of presentation: oral Authors: Doris Krabel, Matthias Meyer, Gerhard Helle, Björn Günther Presenter: Professor Doris Krabel Technische Universität Dresden Pienner Str. 7 D-01737 Tharandt DE 035203-3831202 [email protected] Abstract: Within the last decade Populus spec. (L.) has been developed to one of the main research objects of molecular genetics on woody plants. Among others two reasons for this attractiveness is that most Poplar species are easy to propagate compared to other tree or shrub species which makes a high-throughput cultivation of the plants possible and secondly the genome is comparably small (˃ 41,000 protein coding genes). Both are favourable characteristics for a plant/plant species to become a model organism. Additionally due to the favourable volume to density relation of wood, the production of fast growing trees for bioenergy purposes became more and more attractive for economy. Because of this development foresters and tree breeders focused in search of genotypes of poplar and other fast growing tree species like willow suitable for cultivation in short rotation coppices. But despite the above mentioned positive aspects the major problem concerning short rotation coppices of poplar is their low profit due to a high water demand for satisfactory biomass production. For the description of drought tolerance in aspen we started to identify changes in the tree ring architecture. There our investigations are focused on tree ring width, fibre cell length, vessel cell length, mean annual δ 13C as well as mean X-ray density as part of a functional genomics approach. 33 Chlorophyll a fluorescence to phenotype wheat genotypes for heat tolerance Type of presentation: oral Authors: Eva Rosenqvist1, Carl-Otto Ottosen2, Dew Kumari Sharma1 and Sven Bode Andersen1 1Department of Agriculture and Ecology, Faculty of Life Sciences, Copenhagen University, Frederiksberg C, Denmark 2Department of Food Science, Aarhus University, Aarslev, Den Presenter Dr. Carl-Otto Ottosen Dept. of Horticulture Kirstinebjergvej 10 5792 Årslev DK +4522903105 [email protected] Abstract: Wheat (Triticum aestivum L.) is a heat-susceptible crop throughout its phenological stages, flowering phase being the most sensitive stage. Early stress detection method with advanced physiological measurements may provide new dimensions to establish a high throughput phenotyping method. Chlorophyll a fluorescence has been a versatile tool in photosynthesis research to measure plant responses to various abiotic stresses that affect PSII. We aim to establish a reproducible protocol to measure response of wheat genotypes to high temperature, based on the physiological marker, maximum quantum efficiency of PSII photochemistry (Fv/Fm). We subsequently used this standardized protocol for mass screening of wheat genotypes. Our results showed that the temperature of 40°C in 300 µmols m-2s-1 light for 72 h was appropriate to induce heat stress to reveal genetic variation among cultivars. Initial phenotyping of 1300 wheat genotypes at a milder stress at 38oC for 2 h showed a heritability of 7% for Fv/Fm. However, a harsher stress at 40oC for 72 h in repeated experiments on 138 extreme performing lines resulted a genotype dependent drop in Fv/Fm and an increased genetic component of 15%. Our protocol seems to be stable over environments since interaction between genotypes and the three repeated experiments separated in time was not statistically significant. The chlorophyll a fluorescence protocol may enable identification of wheat lines reliably more or less tolerant to heat treatment at 40oC. Such differential lines can subsequently be used to study the genetic and physiological nature of stress tolerance, facilitating genetic dissection of quantitative trait into simpler and more heritable traits. More detailed studies on the interaction between different temperatures and elevated CO2 during the growth phase reveal that the sensitivity of the cultivars might be reduced due to higher temperatures and CO2, but the patterns remain the same. 34 High Throughput Phenotyping for the Improvement of Crop Stress Tolerance Type of presentation: oral Authors: Adel Zayed, Monsanto Company, RTP, NC, USA Presenter Dr. Adel Zayed Monsanto Company 110 T.W.

Walp.] Type of presentation: oral Authors: Nouhoun BELKO1, 4, Mainassara ZAMAN-ALLAH2, Ndeye Ndack. DIOP1, 3, Ndiaga CISSE1, Gerard ZOMBRE4, Jeffrey. D. EHLERS3, Vincent VADEZ2,* Presenter: Dr. NOUHOUN BELKO CERAAS BP 3320 Thies-Escale, Thies (Senegal) BP 3320 Thies Thies SN 00221 70 455 75 63 [email protected] Abstract: Drought stress is one of the major abiotic constraints that limit agricultural productivity in the semi-arid tropics where climate change is likely to make droughts even more severe for the future. For enhancing performance of crops facing terminal drought stress like cowpea, the traits related to how plants manage limited water resources are essential. In this work, the growth, transpiration rate [TR], canopy temperature [CT] and index of canopy conductance [Ig] of cowpea lines contrasting for their response to drought in the field were tested under non-limited water conditions across different atmospheric vapor pressure deficit [VPD] to investigate whether tolerant and sensitive genotypes differ for the control of leaf water-loss. Overall, plants developed larger leaf area under low than under high VPD conditions and there was a consistent trend of lower growth in tolerant than in sensitive lines. Substantial differences were recorded among genotypes for their TR response to VPD with tolerant showing significantly lower TR than sensitive ones especially at the time of the day with the highest VPD. Significant variations were also found among genotypes for their response of TR to increasing VPD with some tolerant genotypes exhibiting a clear VPD breakpoint at about 2.25 kPa above which there was very little increase in leaf water-losses. In contrast, the sensitive lines presented a linear increase in TR as VPD increased. CT estimated by thermal imagery correlated well with TR and Ig and could therefore be used as proxy for TR. These results indicated that the control of TR discriminated tolerant from sensitive genotypes and may, therefore, be used as reliable indicator of terminal drought stress tolerance in cowpea. The water saving characteristics exhibited by some lines are hypothesized to make more soil water being available for pod filling stage, which is crucial for terminal drought situations.

In order to capitalise on the vast knowledge gained through genomics (and other -omics) research, scientists must alleviate the “phenotyping bottleneck” in plant sciences. Improvements can only be made by interdisciplinary research and knowledge links that integrate the advances that have been made in sensor, imaging and computing technology to accelerate breeding methods, reduce experimental resource requirements and enable multiple, simultaneous and objective data to be collected and analysed. CROP.SENSe.net brings together researchers from plant science, soil science, geodesy, IT, maths and physics with partners from breeding and industry to develop and apply phenotyping science for plant and soil analysis in the lab and field, so as to non-destructively and quantitatively analyse and screen plant phenotype throughout the plants' life cycle. The ultimate aim of this interdisciplinary project is early, non-biased and faster assessment of traits to enable greater efficiency in crop breeding and to optimise decision making in crop management. CROP.SENSe.net research uses a wide array of sensor technologies over almost the complete range of electromagnetic radiation: stereo imaging, visible and multispectral analysis, infrared, wideband radar, TeraHertz and magnetic resonance spectroscopy. A range of external (morphology and growth dynamics) and internal (physiological) architectural and stress-related characteristics of individual plants and populations are measured over the growing season, for the proxy plants barley and sugar beet. An important element is making “hidden” structures and functions visible. Intelligent data evaluation is enabling analysis of information on plant phenotype over space and time on the same plants. Data fusion – merging data (signals) from different sensors is ongoing so as to enable early identification of plant traits and to link this with reference analysis of biochemical and physiological stress indicators, and ultimately back to genotype. 38 CROP.SENSe.net is jointly led by Prof H Goldbach and Prof J Leon, Agriculture Faculty, University of Bonn and Prof U Schurr Institute of Bio- and Geosciences, Forschungszentrum Jülich. It is funded by the German Federal Ministry of Education and Research (BMBF) for 5 years within the scope of the competitive grants program Networks of excellence in agricultural and nutrition research (Funding code: 0315529). 1 University of Bonn, Faculty of Agriculture 2 Forschungszentrum Jülich, IBG-2: Institute of Bio- and Geoscience PARTNERS (in alphabetical order): Bayer CropScience; University of Bonn, Faculties of Agriculture, Mathematics and Natural Sciences, and Institute of Molecular Physiology and Biotechnology of Plants; Cologne University, Institute of Geography; Emisens GmbH; Forschungszentrum Jülich, Institut für Bio- und Geowissenschaften, Pflanzenwissenschaften IBG 2 and Agrosphere IBG 3; Fraunhofer Institute for High Frequency Physics and Radar Techniques (FHR); Fritzmeier Environment GmbH & Co.

An interdisciplinary approach based on high-throughput phenotyping under controlled and field conditions will generate data that will be used for ecophysiological modeling to predict the performance of maize and wheat under fluctuating water regimes. The identification of Quantitative Trait Loci (QTLs) for morpho-physiologcal traits that influence yield under drought conditions will produce additional data for modeling crop performance based on QTL effects. The project will target root architecture, transpiration efficiency, vegetative growth maintenance and seed abortion. In particular, DROPS will: - Develop new screens that will consider indicators which are (i) highly heritable and measurable in a high-throughput fashion in phenotyping platforms; (ii) based on metabolite concentration, sensitivity parameters of models or hormonal balance; (iii) genetically related to target traits and able to predict genotype performance in the field via simulation and/or statistical models; - Explore the natural variation of the target traits by (i) linking the target traits to physiological pathways, genes or genomic regions (ii) assessing the effects of a large allelic diversity for the four target traits via association genetics; - Support crop improvement strategies by developing methods for estimating the comparative advantages of relevant alleles and traits in fields with contrasting drought scenarios. This will be achieved via field experiments and by developing new crop models able to estimate the effects of alleles on crop growth, yield and water-use efficiency. 40 European initiatives on phenotyping platforms Type of presentation: oral Authors: S.

The presentation will remind the strategic interests for Europe to develop a strong Phenotyping community and the different projects that have been funded under the FP7 programme of DG Research&Innovation. 41 How Sclerotinia sclerotiorum meddles with programmed cell death signaling to savour its vegetable host? Type of presentation: poster Authors: Claudine Balagué, Derry Voisin, Laure Perchepied, Bruno Grezes-Besset and Dominique Roby.

The model plant Arabidopsis thaliana, close relative of rapeseed (Brassica napus) and natural host from this ascomycete phytopathogen (Wang et al., 2008), displays a high level of natural variation of resistance/susceptibility to S. sclerotiorum reflecting variable degrees of success in host colonization and induction of programmed cell death (PCD) (Perchepied et al., 2010). By challenging A. thaliana mutants affected in different signaling pathways leading to resistance, we previously determined that resistance to S. sclerotiorum mostly depends on jasmonic acid, absiscic acid and ethylene signaling. In resistant ecotypes such as Columbia-0 and Rubezhnoe-1, the Reactive Oxygen Species (ROS) H2O2 and Nitric Oxyde (NO) were found to accumulate quicker; as a consequence of this earlier oxidative burst, local cellular response may offer stronger protection against the fungus. Interestingly, S. sclerotiorum was recently found to produce oxalic acid to buffer the effect of reactive oxygen species (ROS) from its host upon challenge. Once successful infection has taken place, the effect of the phytotoxin stops and PCD is launched in invaded tissues (Williams et al., 2011). So the possible manipulation of key regulators of PCD by this pathogen constitutes an attractive hypothesis. We propose to test it by using lesion mimic mutants (lmm) that are impaired in the initiation or the repression of controlled cellular suicide (Lorrain et al., 2003). Screening through a relevant collection of lesion mimic mutants and determination of the role of key regulators of PCD will be presented. 42 References: Ai-rong Wang, Wen-wei Lin, Xiao-ting Chen, Guo-dong Lu, Jie Zhou and Zong-hua Wang, 2008.

Box 619, 6700 AP Wageningen, The Netherlands * These authors contributed equally Presenter: Karen Kloth Wageningen University Postbus 8031 6700 EH Wageningen NL 0618671349 [email protected] Abstract: In nature, plants display an enormous degree of natural variation in defensive mechanisms against insect herbivory. So far, agriculture has exploited only little of this diversity of defenses and as a consequence environment-malignant and costly pesticides remain a dominant method to control pests and diseases. Host-plant resistance is one of the cornerstones of environmentally benign pest management systems such as Integrated Pest Management (Panda and Khush 1995; Schoonhoven et al. 2005). However, a major impediment in selecting resistant crop lines is that large numbers of crop lines need to be screened for the effects they have on pest insects. Moreover, the mechanisms of resistance to one pest are not necessarily also effective to another pest so that different pest species require their own approach. To breed for crops that are resistant against insect pests, usually targeted approaches are taken to identify genes involved in resistance. In this study we will use a genetical genomics approach to identify mechanisms underlying natural resistance to sucking insect pests. We will develop a novel automated video-monitoring method to screen insect behavior and performance on 350 wild type accessions (HapMap collection) of Arabidopsis thaliana that have been collected globally and genotyped for 250.000 SNPs . Via this high-throughput system, the resistance against two major agricultural insect pests will be screened, the green peach aphid, Myzus persicae, and the Western flower thrips, Frankliniella occidentalis. The phenotypic data and high resolution haplotype map of Arabidopsis thaliana will be used for association mapping of the genetic loci involved in the 44 resistance. We will subsequently identify genes and molecular markers for different resistance mechanisms in the model plant Arabidopsis. 45 Decoding salt tolerance at the root Type of presentation: poster Authors: M.M.Julkowska, M.A. Haring, C. Testerink Presenter: Magdalena Julkowska SILS/University of Amsterdam Science Park 904 1098XH Amsterdam NL +31205258436 [email protected] Abstract: Salt tolerance is an extremely complex trait involving many signalling pathways and different adaptation strategies. The root is important for observations regarding salt stress. It is the first organ to be exposed to salt and without necessary adaptations it won’t be able to extract enough water required for plant survival. Because of the trait complexity, single gene knockout mutants often fail to provide answers. In my project I am looking for natural variation in salt tolerance within the Arabidopsis HapMap collection. By characterizing the 350 different accessions for salt-induced changes in Root System Architecture and subsequent Genome Wide Association mapping, I aim to identify novel loci / alleles that are responsible for increased salt tolerance. 46 New Genotype To Phenotype Models At The Intersection Of Genetics, Physiology And Statistics; Smart Tools For Prediction And Improvement Of Crop Yield Type of presentation: poster Authors: Fred van Eeuwijk, Anja Dieleman, Alain Palloix , Marnik Vuylsteke, Chris Glasbey, Attila Barocsi, Juan Jose Magan Cañadas, Ep Heuvelink, Gerie van der Heijden, Roeland Voorrips, Marco Bink Presenter: Dr. Marco Bink Biometris - Wageningen UR Droevendaalsesteeg 1 6708PB Wageningen NL +31 317 481072 [email protected] Abstract: The prediction of phenotypic responses from genetic and environmental information is an area of active research in genetics, physiology and statistics. Rapidly increasing amounts of information become available on the phenotype as a consequence of high throughput phenotyping techniques, while more and cheaper genotypic data follow from the development of new genotyping platforms. In between genotype and phenotype, a wide array of -omics data can be generated. Continuous monitoring of environmental conditions has become an accessible option. This wealth of data requires a drastic rethinking of the traditional quantitative genetic approach to modeling phenotypic variation in terms of genetic and environmental differences. Where in the past a single phenotypic trait was partitioned in a genetic and environmental component by analysis of variance techniques, we nowadays desire to model multiple, and often time dependent, phenotypic traits as a function of genes (QTLs) and environmental inputs, where we would like to include intermediate genomic information as well. The U project ‘Smart tools for Prediction and Improvement of CropYield’ (KBB -2008-211347), or SPICY, aims at the development of genotype-to-phenotype models that fully integrate genetic, genomic, physiological and environmental information to achieve accurate phenotypic predictions across a wide variety of genetic and environmental configurations. In the presentation the objectives and structure of SPICY as well as its philosophy will be discussed 47 Impact of Potato virus Y infection on plant growth and symptom expression in different potato cultivars Type of presentation: poster Authors: M.

The tuber necrotic strain of Potato virus Y (PVYNTN) causes potato tuber necrotic ringspot disease (PTNRD) in sensitive potato (Solanum tuberosum L.) cultivars that is responsible for great losses in crop industry. Sensitive cultivars of potato infected with PVYNTN show growth inhibition, faster senescence and leaf drop, chlorotic ringspots and/or spot necrosis on inoculated leaves, crinkles and mosaics on systemic infected leaves and necrotic ring spots on tubers. Viruses from PVYN-Wi group can also cause severe symptoms on potato. Symptom development and their severity depend on the isolate of PVY, potato cultivar, environmental conditions and other factors. In our studies, differences in growth inhibition, senescence, leaf drop and symptom appearance on leaves of four susceptible potato (Solanum tuberosum L.) cultivars after the infection with two isolates of Potato virus Y, PVYNTN and PVYN-Wi, were monitored at different times after infection. The results were complemented with microarray and quantitative real-time PCR analyses of differentially expressed genes. Kogovšek et al. (2011) Phytopathology in press. Kogovšek et al.

This paper presents the experience of developing an automatic vision based system for plants in greenhouses. The proposed system addresses the problem of acquiring images in multiple specified locations inside a greenhouse. It allows the use of different capturing devices (single camera, stereo head, and time of flight camera) as well as lasers and light sources that can be positioned in specific locations at repeatable positions. The system proposes an alternative to the approach with multiple cameras placed in fixed position inside a greenhouse, offering a lower cost solution by means of dedicated electromechanical devices able to carry the video sensors to the locations of interest along a rail system. Moreover, camera position (pan and tilt) and zoom are also programmable for each location allowing for extra flexibility. The proposed setup is a fully wireless one. It can accommodate IP cameras offering power from contained batteries that are charged with a non-contact energy transmission system that offers the robustness to the environmental conditions found inside greenhouses 49 Ultra-low density in field experiments accentuates phenotypic expression and differentiation Type of presentation: poster Authors: I.

The scope of this work is to emphasize how plant-to-plant distance affects phenotypic expression and differentiation. It is now widely adopted that phenotypic expression increases as density declines, achieving a plateau at a very low density. In essence this critical very low density ensures elimination of any plant-to-plant interference for resources, in other words approaches absence of interplant competition. Our data from studies in maize, wheat, cotton and common bean conducted under both the typical for each crop density and the absence of competition clearly illustrate that in the latter condition the third determinant parameter of the above mentioned equation, i.e. phenotypic differentiation, also maximizes for several agronomic traits. In other words, absence of competition by accentuating phenotypic differences among genotypes facilitates breeder’s decision on single-plant selection. Consequently, absence of competition is the optimal density condition to apply crop breeding and reach the highest possible success in selection effectiveness, given that it allows application of high selection intensity and optimizes heritability and phenotypic differentiation.

On these soils, plant growth may be aimed either for phytoremediation or for biomass production. For the first, an extended development of the root system is desired, whereas for the latter, this should be avoided. Therefore, careful quantification of root growthinhibiting and -activating responses by the contaminant(s) is crucial for optimal use of plants on contaminated soils. We routinely expose Arabidopsis thaliana wild-type and mutant plants to contaminants on vertical agar plates and image root systems at 600 dpi using a conventional flatbed scanner (Canon Canoscan 4400F) before manual measurement of only three primary root architectural parameters (length of primary root, length and placement on primary axis of lateral roots) using Optimas Image Analysis software (Media Cybernetics). Also, a large number of secondary root growth parameters that are informative of the responses are then calculated from these primary measurements using a self-developed automated Microsoft Excel sheet. Using this system, we revealed that three different metals caused distinct effects on lateral roots (LRs). Both cadmium (Cd) and copper (Cu) exposure caused an increase in LR density, but elongation of these LRs was more severely inhibited by Cd and less by Cu. In zinc (Zn)exposed plants, a decrease in both LR density and LR elongation was observed. Stressinduced morphogenic responses (SIMRs), consisting of a combination of both growth promoting and inhibiting responses that result in a redistribution of growth leading to stress avoidance, had been described [1], and it was assumed that whichever abiotic stress would always lead to similar responses due to common underlying molecular mechanisms [1,2]. Our observations challenge this idea as we observed three different responses for the three different metals. Furthermore, the response to Cu resembles the response to P-deprivation, but the use of a split-root system revealed that the response to Cu is strictly local, unlike the systemic trigger of the low-P response by perception in the primary root tip. 51 These metal-specific morphological responses indicate the existence of underlying metalspecific sensing and signalling pathways that lead to distinct responses. Application of forward genetics would identify molecular components, but high throughput phenotyping systems are necessary. Therefore, in a reverse genetics approach, mutants in genes related to root growth and hormonal signalling are being studied to identify the underlying molecular components. Furthermore, the effect of plant-associated bacteria on root morphogenesis under Cd- and 2,4-DNT-induced stress conditions was investigated. Whereas 1 mg L-1 2,4-DNT was severely toxic to Arabidopsis seedlings, leading to 80 % reduction of root length, inoculation of the plant growth agar with DNT-degrading bacteria partially relieved the growth inhibitory effect, resulting in a doubling of the root length in comparison with exposed non-inoculated plants. This was due to the combined effect of plant-growth promoting characteristics of the bacteria under pollution conditions and the detoxification of 2,4-DNT to less harmful products. From an ecological point of view, we are interested in quantifying the effectiveness of the specific responses, not only to avoid the stress condition, but also to colonize less or noncontaminated areas. Here, plant-associated bacteria may assist the plant in tolerating the contamination and colonize contaminated soils. Similar experiments may be conducted for other (plant species x associated bacteria) interactions to evaluate the effectiveness of colonizing contaminated patches for phytoremediation purposes. High throughput phenotyping will clearly accelerate discoveries in this area. [1] Potters et al. (2007) Trends in Plant Science 12:98-105. [2] Potters et al.
