| Popis: | Plant growth-promoting rhizobacteria (PGPR) can potentially be used as an alternative strategy to control plant diseases. In this study, strain ST&ndash TJ4 isolated from the rhizosphere soil of a healthy poplar was found to have a strong antifungal activity against 11 phytopathogenic fungi in agriculture and forestry. Strain ST&ndash TJ4 was identified as Pseudomonas sp. based on 16S rRNA-encoding gene sequences. The bacterium can produce siderophores, cellulase, and protease, and has genes involved in the synthesis of phenazine, 1&ndash phenazinecarboxylic acid, pyrrolnitrin, and hydrogen cyanide. Additionally, the volatile compounds released by strain ST&ndash TJ4 can inhibit the mycelial growth of plant pathogenic fungi more than diffusible substances can. Based on volatile compound profiles of strain ST&ndash TJ4 obtained from headspace collection and GC&ndash MS/MS analysis, 1-undecene was identified. In summary, the results suggested that Pseudomonas sp. ST&ndash TJ4 can be used as a biocontrol agent for various plant diseases caused by phytopathogenic fungi. |
