Three Pseudomonas strains
Three bacteria were isolated from the rhizosphere soil of wheat in a high yield farmland in Handan, Hebei province, PR China, named S9205, S9268 and S9792 respectively. The three strains showed some plant growth-promoting traits, such as producing IAA, NH3 and siderophore, solubilizing organic and inorganic phosphorus, suggesting their plant benificial roles. The results of multiphasic taxonomic approach, including overall genomic relatedness indices (average nucleotide identity and, digital DNA-DNA hybridization), phylogenetic analysis (based on the 16S rRNA gene and, multilocus sequence analysis), physiological and biochemical taxonomic features proved that the strains represent two novel species of the genus Pseudomonas.
