Neighbor-joined phylogenetic tree of Pseudomonas fluorescence PGPR-7. The tree was constructed based on 16S rRNA partial gene sequence and closely related phylogenetic species (type cultures) derived using the NCBI BLAST search tool. Sequences were aligned using Clustal W sequence alignment tool in MEGA 7.0 software. The GenBank accession numbers of isolates and closely related species are presented in brackets.
