Project 1:Crying for help: unravel the defending strategies of plant under biotic stress.I NRAE supervisors: Sylvain Jeandroz, Marion Prudent, Christophe SalonCAU supervisor: Chunxu SongPlants have evolved effective defense mechanisms that fend off most of pathogen attacks. These defenses including anti-microbial compounds and cell wall reinforcement are triggered when plant receptors recognized compounds of the pathogen or compounds delivered during pathogen attacks, called PAMPs/DAMPs/MAMPs or more generally elicitors of plant defense. However, the underlying molecular mechanisms of how plant immunity affect plant-associated microbial communities, particularly beneficial microbes, are largely unknown. This knowledge is important to reciprocally better understand the effect of microbes on plant immunity by symbionts and to improve methods of biological control. Therefore, in this project, we are aiming to: 1) investigate the plant response and performance under biotic stress (in this case exposure to elicitors), in presence and absence of soil microbes.2) investigate the underlying mechanism of how plant recruit their associated microbiome under biotic stress.Taken together, this will provide insight on how plants select their microbial communities under biotic condition and how microbiota could influence plant immunity (IR). Meanwhile, it will also reveal how beneficial microbes can promote plant performance.For more information related to this project, please contact us via chunxu.song@cau.edu.cn or sylvain.jeandroz@agrosupdijon.fr or marion.prudent@inrae.fr
