Abstract

The present invention relates to a new mutant Rhizobium etli CNPAF 512 strain, having an inactivated raiI gene. Inactivation of the raiI gene leads to increased nodule number in beans upon inoculation thereof with the mutant strain. Based on this specific strain other strains can be mutated in the similar gene(s) in order to enable nodule increase and nitrogen fixation in other Leguminosae species.
