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…

Evaluation in vitro du potentiel anthelminthique de la graine de lupin, Lupinus spp.

National audience; Le lupin, protéagineux déjà utilisé en nutrition animale, contient des alcaloïdes qui pourraient avoir des vertus anthelminthiques. Notre étude s’attache à valider et quantifier ces propriétés par des tests in vitro exposant Haemonchus contortus, strongle parasite de ruminants, à différents extraits de deux variétés, riche (amère) ou pauvre (douce) en alcaloïdes. L’analyse des alcaloïdes présents a révélé une teneur plus élevée dans la variété amère (3.3% contre 0.04% dans la variété douce), mais une diversité supérieure dans la variété douce (n=5 contre 3 dans la variété amère). Les différents extraits des variétés testées ont paralysé significativement les stades larvai…

Towards bruchid resistance in pulses

Prod 2019-88ff BAP GEAPSI INRA; National audience; Seed weevils (Bruchus spp.) are major pests of pulses, causing yield losses and affecting marketability 1,2 . Available insecticides have low efficiency and important negative impacts on the environment, humans and non-target organisms. Therefore, breeding resistant varieties represent the most promising strategy to overcome seed weevils. The pyramiding of several resistance genes in cultivars is an important objective because this will make the resistance more durable and suitable for sustainable agriculture. The PeaMUST project (ANR-11-BTBR0002) aims at discovering the mechanisms of tolerance and resistance to bruchids in pea (Pisum sativ…

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…
