Phenotyping, ecophysiology and molecular physiology to characterize plant root system architecture and plant-plant and plant-microorganisms interactions
International audience; Agriculture is facing the challenges to improve performance and crop adaptation to climate change towards reducing negative impacts of associated abiotic stresses on crop yield and contributing to its mitigation. Climate change comprises more frequent and ample abiotic stresses that plants have to cope with, such as drought, the most important limitation to yield stability and plant harvest product quality which often lead to hydromineral nutritional stress. The capacity of plants to extract nutrients and water from a given volume of soil depends on root system architecture and on intrinsic factors such as the production of root exudates and the efficiency for resour…
Challenges and opportunities for innovative research on legume nutrition and stress adaptation: an ecophysiologist’s and phenotyping point of view
International audience; Agroecology needs to reconcile agronomy and ecology, preserving and valorizing plant and microbe biodiversity. Legumes have merits for agroecology considering their ecological services. They constitute a protein source and their production relocation give merits for feed and food. However, they are still under represented due to both biotic and abiotic constraints. Research need to increase their profitability through higher and more stable yield and protein content, and new uses in a fluctuating environment [2]. Mechanisms which control nutrient use efficiency have to be highlighted i) considering nutrient acquisition, storage, remobilization [3] ii) under various c…

Rhizodeposition as a functional trait in legumes. Study of trade-off for plant productivity and resilience
Rhizodeposition is the release of organic carbon (C) to the soil that connects the biotic and abiotic components of the C cycle. It can promote C storage to soil but also mediates plant-microbe interactions (Jones et al., 2009). These interactions are complexes as rhizodeposition will influence the composition and functioning of microbial populations which in return are able to increase the availability of nutrients in soil and provide protection against pathogens (Sasse et al., 2018). Despite their importance for current agriculture challenges, plant-soil microbes interactions remain poorly understood due to the methodological challenge they represent and the complexity of actors and proce…
