Phylogenetic tree based on <i>gyrB</i> (A) and <i>recA</i> (B) sequences of the five rice-associated bacteria (RABs) and other <i>Bacillus</i> species from GenBank nucleotide database.

<p>GenBank accession numbers for the sequences obtained from the database are given in parentheses. The tree was generated using neighbor-joining method, and genetic distances were calculated using the Kimura 2-parameter method using MEGA5 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0146764#pone.0146764.ref076" target="_blank">76</a>]. Numbers at nodes indicate percentage of occurrence in 1000 bootstrapping. The bar at the bottom of the tree indicates the scale for genetic distances. <i>Burkholderia glumae</i> 336gr-1 was used as an out-group control.
