At major nodes, bootstrap percentages for 1,000 re-samplings are shown. The scale bar represents 0.1 nucleotide substitution per nucleotide position. Bacillus species include Bacillus aerophilus 28K (GenBank accession no. AJ831844), B. altitudinis 41KF2b (AJ831842), B. amyloliquefaciens BCRC 11601 (NR_116022), B. amyloliquefaciens ATCC 23350 (X60605), B. amyloliquefaciens LN (KP261025), B. anthracis ATCC 14578 (KC119183), B. licheniformis DSM 13 (X68416), B. mojavensis CR-95 (AY603656), B. mycoides ATCC 6462 (NR_115993), B. pseudomycoides JCM 12231 (LC107614), B. pumilus ATCC 7061 (AY876289), B. safensis FO-036b (AF234854), B. sonorensis NRRL B-23154 (NR_025130), B. subtilis subsp. subtilis DSM 10 (AJ276351), and Bacillus thuringiensis ATCC 10792 (NR_114581). Pseudomonas aeruginosa ATCC 10145 (NR_114471) was used as an outgroup to root the tree.
