Plant-microbiome interactions: importance of miRNAs regarding nitrogen acquisition
The goal of this project is to understand how plant miRNAs influence the soil microbiome. Our preliminary results suggest that plant miRNAs may represent a competitive tool against microorganisms for nitrogen resources present in the soil. Therefore, miRNAs produced by two plant models (Arabidopsis thaliana and Brachypodium distachyon) will be analyzed under 3 fertilizing conditions. Putative bacterial targets will be explored. Finally, certain bacterial strains will be selected and confronted to plant miRNAs allowing us to authenticate the targets.
