Phylogenetic dendrogram inferred from the 16S rRNA sequences, showing the relationships between P. polymyxa isolate APEC136 and related Paenibacillus species (a) and B. subtilis isolate APEC170 and related Bacillus species (b)

Bootstrap values (expressed as percentages of 1000 replications) greater than 50% are shown at branch points, and species names are preceded by NCBI-GenBank accession numbers. The trees were generated using maximum parsimony in MEGA 4.0. The scale bar indicates 0.02 substitutions per nucleotide position
