From: First report of diazotrophic Brevundimonas spp. as growth enhancer and root colonizer of potato
Phylogenetic tree based on nifH gene sequences (300 bp) of Brevundimonas spp. strains isolated from potato rhizosphere (filled circle) and obtained from published sequences. Numbers present at the branching points are bootstrap values > 90%. Methanosarcina lacustera (AF296355) was kept as root. Bar represents sequence divergence of 0.2 nucleotides.
