Biological Resource Centrers: gateway to biodiversity and services for innovations in biotechnology: proceedings. [Orsay]: WFCCc2010  aRhizobia are bacteria that live in symbiosis with legumes. In Brazil, the species Rhizobium tropici represents the majority of the population isolated from common bean (Phaseolus vulgaris L.) nodules of field grown plants. Since the description of the R. tropici species in 1991, several strains have shown variability in genetic and physiological properties, splitting the strains into two subgroups, R. tropici type A and type B. Currently, the phylogeny of rhizobia, as well as of other prokaryotes is based mainly on the analysis of the ribosomal gene 16S.  aNitrogen fixation  aPhylogeny  aFilogenia  aFixação de nitrogênio  aMLSA1 aHUNGRIA, M.
