A bacterial strain IB-4, antagonistic to plant pathogenic fungi of the genera Fusarium, Bipolaris, and Alternaria, was isolated from arable soils of the Mechetlinskii district, Bashkortostan. Physiological, biochemical, and culture morphological properties of strain IB-4 supported its classification within the genus Pseudomonas. In spite of some discrepancies in the results of phenotypic and chemotaxonomic research, analysis of the 16S rRNA gene sequence, DNA-DNA hybridization, GC-content, and MALDI mass spectral data provide considerable evidence supporting its identification as a Pseudomonas koreensis strain. P. koreensis strain IB-4 was shown to possess the valuable features characteristic of PGPR microorganisms: antifungal and nitrogenase activities and ability to synthesize indole-3-acetic acid (IAA) and cytokinin-like compounds. Field test, in which potato plants were treated with the culture liquid of P. koreensis strain IB-4 revealed a positive effect on potato yield and resistance to plant pathogens.
