TL;DR: The results revealed a high level of diversity of diazotrophic Burkholderia species, including B. unamae and B. kururiensis, and two other unknown species, which exhibited activities involved in bioremediation, plant growth promotion, or biological control in vitro.

TL;DR: It was shown recently that the genus Burkholderia is rich in N2-fixing bacteria that are associated with plants, and a polyphasic taxonomic study was performed, which indicated that new isolates that were recovered from rhizospheres, rhizoplanes or internal tissues of maize, sugarcane and coffee plants belong to a novel diazotrophic Burk holderia species.

TL;DR: Only 111 out of more than 900 isolates recovered had N2-fixing ability as demonstrated by the acetylene reduction assay, and these 111 isolates were confirmed as belonging to the genus Burkholderia by using a new 16S rRNA-specific primer pair for diazotrophic species (except B. vietnamiensis).

TL;DR: A multilocus sequence analysis of 77 type and reference strains of Burkholderia using atpD, gltB, lepA, and recA genes in combination with the 16S rRNA gene sequence revealed two large groups, named A and B, which suggest that each group might represent a different genus.

TL;DR: Novel isolates were recovered from the roots of different sugar-cane varieties cultivated in diverse geographical regions of Brazil and confirmed that these isolates belong to a novel species within the genus Burkholderia, for which the name Burk holderia silvatlantica sp.
