Development of the root microbiota and plant nitrogen nutrition theme by Benoît Alunni INRAE Senior Scientist appointed to the IJPB

Project : Understanding and exploiting the maize root microbiota for low-input agriculture

Plant root microbiota (bacteria and fungi) plays a major role in plant nutrition, and its engineering could help reducing the input of fertilizers in field crops. The project of Benoît Alunni, who joins the "Symbiotic Nitrogen Acquisition in Plant-Microbe Systems" SYNAPS team, makes use of the maize-Rhizophagus irregularis (vesicular arbuscular mycorrhizal fungus) model developed in the team to understand how mycorrhizal roots recruit soil bacteria that can facilitate their host’s nitrogen nutrition. He is interested in the role of root exudates in the recruitment of microorganisms from endogenous or synthetic/inoculant microbial populations.

In parallel, he participates to the development of the soybean sector in France by studying this legume’s microbiota, with tools and fundamental/applied goals shared with his main project on maize.
