Beyond the sequencing of the pea genome: opportunities for genomics-based breeding and translational approaches

International audience; The tribe Fabeae comprises more than 300 legume species, including some of the most ancient and important crops like Pisum sativum (pea), Lens culinaris (lentil), and Vicia faba (faba bean) used for food and feed. The genome sequence of pea, released in 2019, is an important milestone for the community working on legumes and especially on Fabeae. It brings into light evidences related to the genome expansion that occurred after the divergence of Fabeae from their sister tribes and highlights different chromosomal rearrangement events specific or not to the Pisum lineage. The pea genome sequence also represents a valuable resource to accelerate our understanding of th…

Taking cool-season grain legume breeding to the next level: the key role of the pea genome sequence

International audience; The transition from a standalone phenotypic selection to a marker-assisted selection has been seen as a great step forward to improve the breeding process and reach the expected goals. More recently, the genomic revolution has also had its great impact on breeding. -omics are now part of the required toolkit for a successful, cost and time-efficient breeding. The genome sequence of pea (Pisum sativum) has been made available in 2019 through a collaborative international effort. This is a great tool for the pea community in general and the Fabeae community in particular. Current challenges facing pea and other Fabeae production are numerous. A large number of traits h…

The pea genome and beyond

International audience; The recently generated pea genome sequence is a significant step for the pea research community towards unravelling functional diversity and establishing genome-enabled breeding. Re-sequencing data reveal the considerable diversity present in the Pisum genus. High-throughput genotyping is now available to explore large collections using the exome capture technology in genome-wide association studies (GWAS) or tackle map-based QTL cloning. 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 …
