Abstract
In the face of climate change, new grapevine varieties will have to show an adaptive phenotypic plasticity to maintain production with erratic water resources, and still ensure the quality of the final product. Their selection requires a better knowledge of the genetic basis of those traits and of the elementary processes involved in their variability. ‘PlastiVigne’, an emblematic project of the Vinid’Occ key challenge, funded by the Occitanie Region (France), tackles this issue with innovative genomic and physiological tools implemented on a unique panel of grape genetic resources representing the genetic diversity of Vitis vinifera. A graph-pangenome is developed from a representative set of high-quality genomes to study the extent and impact of structural genome variations and chromosomal rearrangements in the rapid adaptation capacity of grapevine. We will characterize structural variants potentially related to differential expression or alternative spicing of candidate genes for stress tolerance in individual grape berries. Markers derived from structural variants mapped on the pangenome, as well as new sets of SNP markers, will allow the identification of genomic regions associated to leaf water and carbon balance under several water stress regimes, its plasticity, adaptation traits like phenology, genomic vulnerability, and to some traits related to the aromatic potential of grape berries. They represent new tools for grape breeding. More detailed functional analysis of leaf and berry phenotypic plasticity in response to water deficit will be then conducted, on a subset of contrasted varieties. We will present the project strategy and highlight a few preliminary results.
