  1. Gene annotations and comparisons were obtained from IMG database [39]. Numbers of conserved and specific genes in each strain determined by comparison to other PGPR genomes. Genes with homology (H) values less than 0.42 and more than 0.81 were arbitrarily defined as specific and conserved, respectively.
