The Pea genome and after …

Abstract

International audienceHaving a genome sequence available is a critical step towards unravelling functional diversity andestablishing genome-enabled breeding. The recently generated pea genome sequence represents a great toolfor genomicists, geneticists and breeders not only for the pea community but also for legume research. In thegenome project, re-sequencing data revealed the considerable diversity present in the Pisum genus. In thePeaMUST project, an unprecedented effort was made to genotype large pea collections using the exomecapture technology. This high-density SNP data was exploited in genome-wide association studies (GWAS) ona large number of traits related to yield, as well as response to biotic and abiotic stresses. Comparative GWASand meta-QTL analysis identified important putative loci involved in the control of yield and its components inpea. Furthermore, genomic selection strategies have been developed in order to tackle complex traits such asyield regularity and improve selection efficiency. We will present snapshots of these results and discusspotential transfer of knowledge from pea to related crops
