Neighbor-joining phylogenetic tree based on concatenated sequences of atpD, glnII, and recA genes showing the relationships of 18 representative strains (in bold) and related taxa. Reference type strains are indicated with superscripted T. Numbers at nodes indicate bootstrap percentages (based on 1000 resampled datasets). Only node supports higher than 50% are shown. The length unit of 0.02 indicates 2% of the genetic distance
