  abstract = {{T}he genetic diversity of 221 {M}imosa pudica bacterial symbionts trapped from eight soils from diverse environments in {F}rench {G}uiana was assessed by 16{S} r{RNA} {PCR}-{RFLP}, {REP}-{PCR} fingerprints, as well as by phylogenies of their 16{S} r{RNA} and rec{A} housekeeping genes, and by their nif{H}, nod{A} and nod{C} symbiotic genes. {I}nterestingly, we found a large diversity of beta-rhizobia, with {B}urkholderia phymatum and {B}urkholderia tuberum being the most frequent and diverse symbiotic species. {O}ther species were also found, such as {B}urkholderia mimosarum, an unnamed {B}urkholderia species and, for the first time in {S}outh {A}merica, {C}upriavidus taiwanensis. {T}he sampling site had a strong influence on the diversity of the symbionts sampled, and the specific distributions of symbiotic populations between the soils were related to soil composition in some cases. {S}ome alpha-rhizobial strains taxonomically close to {R}hizobium endophyticum were also trapped in one soil, and these carried two copies of the nod{A} gene, a feature not previously reported. {P}hylogenies of nod{A}, nod{C} and nif{H} genes showed a monophyly of symbiotic genes for beta-rhizobia isolated from {M}imosa spp., indicative of a long history of interaction between beta-rhizobia and {M}imosa species. {B}ased on their symbiotic gene phylogenies and legume hosts, {B}. tuberum was shown to contain two large biovars: one specific to the mimosoid genus {M}imosa and one to {S}outh {A}frican papilionoid legumes.},
