Phylogenetic tree highlighting the relative position of B. velezensis ZF2 among other Bacillus species. The phylogenetic tree was constructed based on four housekeeping genes (16S rRNA, rpoD, pgk, and gyrB) according to the aligned gene sequences using the maximum likelihoods method in MEGA 6.0. Bootstrap values (1,000 replicates) are shown at the branch points. The scale bar indicates 0.01 nucleotide substitution per nucleotide position. GenBank accession numbers associated with the housekeeping loci for all strains are presented in Table S2
