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 and GRASP 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, symbiose, as well as response to biotic and abiotic stresses. Furthermore, transcriptomics experiences were able to unravel or confirm mechanisms linked to nutrient remobiization in leaves or seeds. We will present snapshots of these results using the genome, discuss limits of this assembly and how we can improve it.
