Biological Resource Centrers: gateway to biodiversity and services for innovations in biotechnology: proceedings. [Orsay]: WFCCc2010 aThe genus Bradyrhizobium encompasses a variety of bacteria that can live in symbiotic and endophytic associations with legumes and non-legumes, and are characterized by physiological and symbiotic versatility and broad geographical distribution. In studies with Bradyrhizobium strains the comparison of phylogenies of nodulation and housekeeping genes has indicated a monophyletic origin of nodulation genes and diffusion by vertical and horizontal gene transfer, the last one probably influenced by the host plants. aNitrogen fixation aFixação de nitrogênio aAnálise filogenética1 aRIBEIRO, R.
