Biography:
Using the Phaseolus vulgaris / Rhizobium interaction model, the project focuses on the microRNAs and PhasiRNAs regulating the symbiotic nitrogen fixation, from the diffusible factors exchange to the senescence of the symbiotic organs called nodules. Many of these small RNAs are common bean-specific and provide new insights into the co-evolution between the bacteria and their host. The variety of Phaseolus vulgaris genotypes is estimated at several tens of thousands widespread around the world. This pool of common beans represents a powerful tool to investigate the small RNA variability at an intra-specie scale and the influence of these variations on the establishment of symbiotic nitrogen fixation.
Research Areas:
- Small RNAs
- Nitrogen fixation
- Symbiosis
Current N-related Projects:
- The characterization and evolution of the small RNAs involved in the plant-microbe interactions
