Genetic diversity and symbiotic efficiency of rhizobial strains isolated from nodules of peanut (Arachis hypogaea L.) in Senegal

- This is the first report on the genetic and phenotypic diversity of rhizobia associated with Peanut in Senegal.
- We characterize a new collection of Bradyrhizobia strain obtained from peanut nodules in Senegal.
- We compared strains from the peanut center of origin (South America) to strains obtained in Senegal.
- We identify effective strains with potential for use as peanut inoculants.
- Peanut was probably introduced in Senegal without its original strains, or those strains were lost or transformed.
