Phylogenetic tree of 6 bacterial isolates from the rhizosphere of pineapple plants and one control isolate from rice (TPK5B2) based on partial 16 S rRNA gene sequences. The phylogenetic tree was separated between the gram positive (A) and the gram negative (B) bacteria. The tree was built using the maximum-likelihood (ML) method and bootstrap analysis was performed using 1000 replications. Only bootstrap values above 50% were depicted on the tree nodes. Bar, 0.050 substitutions per position.
