Quel impact de la génomique végétale sur l’innovation variétale : l’exemple du projet PeaMUST. Le génome du pois: vers de nouvelles strategies de sél…

2020

International audience; L’avancée des technologies « nouvelle génération » de séquençage de l’ADN permettent une connaissance de plus en plus poussée des génomes et de leur expression. Ces connaissances permettent d’approcher plus finement les déterminants moléculaires des traits phénotypiques et ouvrent des perspectives d’augmentation du progrès génétique dans le cadre de la sélection variétale. Le pois est une espèce modèle depuis les travaux de G. Mendel conduisant à la découverte des lois de l’hérédité. La séquence du génome de cette espèce longtemps délaissée des approches de génomique a récemment été obtenue par un consortium international piloté par l’INRAE (1,2). Dans le cadre du pr…

Identification des déterminants génétiques impliqués dans les défenses du pois contre le puceron Acyrthosiphon pisum.

2021

National audience; Le pois (Pisum sativum) constitue une culture d’importance majeure parmi les légumineuses pour ses qualités de plante protéagineuse, notamment en Europe en réduisant la part de protéines végétales importées ainsi que pour son rôle dans la rotation des cultures en fixant l’azote atmosphérique dans le sol. Cependant, ces dernières années, les rendements ont été rendus instables dus aux contraintes biotiques et abiotiques. Pour lutter contre certains ravageurs, les producteurs ont recours à de grandes quantités de pesticides qui sont coûteuses et dangereuses pour l’environnement et la santé humaine. Pour ces raisons, des alternatives sont mises en œuvre tels que le développe…

Pea MUlti-STress adaptation and biological regulations for yield improvement and stability

2019

National audience; Protein crops including pea are of high environmental and nutritional interest within the current context of climate change and reduction of inputs. However, pea yield irregularity due to multiple biotic and abiotic stresses limits its development in European cropping systems. Targetting muti-stress resistance and seed yield stability, PeaMUST (Pea MUlti-STress adaptation and biological regulations for yield improvement and stability) is an 8-year large French national project (2012- 2020) aiming at improving pea varieties to boost their introduction in cropping systems. Benefitting from an exceptional partnership of 28 public and private organisations and a wide range of…

Key Note speaker Plant resistance and architecture for protection of pulses against biotic stresses

2019

Prod 2019-88l BAP GEAPSI INRA DOCT; National audience; Major diseases and pests, such as root rots, ascochyta blights and aphids, are limiting factors to cool season pulse production in many countries worldwide, especially in Europe. In the context of pesticide reduction, plant genetic resistance and architecture are main traits that can be mobilised in breeding for disease and pest management. Knowledge of quantitative resistance to major diseases and pests of pea and faba bean in France has benefited from the development of sequenced genomes and massive SNP markers [1], which have recently been highly valuable to identify candidate genes controlling resistance. Fine mapping and sequencing…

Genetic diversity of nodulated root structure in a very diverse pea collection

2019

National audience; The root system is responsible for nitrogen (N) acquisition, which in legumes, combines mineral acquisition and symbiotic fixation in nodules. Despite these two complementary pathways, N nutrition may be a limiting factor of legumes yield because nodules are very sensitive to their local environment and N fixing legume root system is poorly developed which may limit soil exploration [1]. Pea establishes in root nodules a symbiotic association with Rhizobium leguminosarum sv viciae bacteria (Rlv) [2]. This study assessed the potential of naturally occurring genetic variability of nodulated root structure and functioning traits to improve yield pea performance. Two successi…
