Fig. 2From: Identification and characterization of the rhizosphere phosphate-solubilizing bacterium Pseudomonas frederiksbergensis JW-SD2, and its plant growth-promoting effects on poplar seedlingsPhylogenic tree showing the phylogenic relationship between JW-SD2 and other representative bacterial strains based on 16S rRNA sequence using the neighbor-joining (NJ) algorithm. Bootstrap values (50 %) were calculated based on 1000 replications shown at nodes of the tree (values < 50 not included). Bar is 0.005 substitutions per nucleotide positionBack to article page
