Research area
The JRU Plant Development and Genetic Improvement (DAP) focuses on the study, management and use of the agro-biodiversity of Mediterranean and tropical crops to identify superior combination of alleles of genes of agronomic interest for delivery in plant breeding schemes. Using quantitative and molecular genetics and genomic technologies, DAP investigates the genetic and molecular control of major agronomical traits (resistance to important diseases and product quality). We participate in the deciphering of the genetic and molecular mechanisms of vegetative development of major plants and their adaptation to abiotic stresses (drought, salinity, oxidative stress, cutting, tapping...) aiming at a continuum from gene to organ, thanks to cutting edge functional analysis, cell imaging and modelling approaches. The integration of genetic and molecular data in a range of dicotyledonous (Apple tree, Olive tree, Cocoa, Coffee, Rubber tree, Cotton, Groundnut) and monocotyledonous (Coconut, oil palm, banana, sugarcane, sorghum, bread wheat and rice) crops, that can be polyploids derived from interspecific hybridizations, allows to study the incidence of evolutive, adaptive and domestication processes on genome diversity in a scale ranging from the structural rearrangements to sequence variation in alleles subjected to these pressures.

Research highlights
Our unit has been a pioneer in the construction of the very first molecular maps in tropical crops namely banana, cocoa, sugarcane, oil palm, coconut, rubber tree and has contributed to major advances in those of cotton, coffee and sorghum. A large effort of construction of the first BAC libraries in these crops has also been accomplished. Structural genomics of the polyploids banana and sugarcane, using molecular cytogenetics, have allowed to a better understanding of recombinations and translocations occurring in these complex genomes. Comparative genomics in the andropogonae has allowed an early establishment of synteny relationships between sorghum and sugarcane by our teams. These resources are being used for mapping resistance to major diseases and quality traits while candidate genes are being pinpointed through mapping of large cDNA resources constructed in our unit. We have largely contributed to the understanding of the structuration of the diversity in target crops of the generation challenge program (GCP) conducting to the constitution of core collections that are precious resources for linking nucleotide variation to phenotypic variation. This association genetics allows to capture genes involved in major trait variation. We are also major stakeholder in international genomics consortia that are conducting the sequencing and functional analysis of the genome of the main tropical crops. In the field of functional genomics, our unit has contributed major resources such as rice insertion line libraries, and information systems and comparative genomics tools linking molecular genetics to gene function across species. We have participated in the understanding of the role small proteins involved in wheat grain quality notably using structural biology, and in the deciphering of the genetic and molecular control of stress tolerance in rubber and of adaptive development of roots in rice. The virtual plants group has an internationally recognized expertise in the modelling of meristem function and of the elaboration of plant shape such as the branched apple tree canopy. Last but not least, DAP hosts genotyping, cell imaging, bioinformatics , rice functional genomics and modelling platforms which are well recognized in the international community.
