The Pea genome and after

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