The Pea genome and after …
Résumé
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.
