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…
Silencing of plant defensin type 1 reduces sensitivity to pathogens and zinc toxicity in arabidopsis thaliana
Ectopic expression of defensins in plants correlates with their increased capacity to withstand abiotic and biotic stresses(Carvalho & Gomes, 2011). However, few studies have explored the effects of decreased plant endogenous defensin transcripts on these stress responses.When over-expressed in Arabidopsis thaliana, some of the seven members of thePlant Defensin type 1 family (PDF1) are recognised to improve plant responses tonecrotrophic pathogens(De Conincket al.,2010)and increase seedling tolerance to excess zinc (Zn;Mirouzeet al., 2006). We carried out an extensive physiological and biochemical comparative characterisation of i) novel transgenic amiRNA lines silenced for the five most s…
