Rhizobacterium streptomyces sp. NEAU-383 as a potential biocontrol agent to control tomato bacterial wilt.

ABSTRACT: The global tomato plants are seriously threatened by soilborne bacterial wilt, which is caused by Ralstonia solanacearum. Biological control agents (BCAs) are considered as a promising strategy. In this study, strain NEAU-383, which exhibited significant inhibitory activity against R. solanacearum, was isolated from the rhizosphere soil of a healthy tomato plant in a serious soilborne diseased field. Based on phylogenetic analysis, ANI values, and digital DNA-DNA relatedness, strain NEAU-383 was included in the genus Streptomyces and may be a potential new species. In pot experiments, both pre-inoculation with the spore suspension and fermentation extracts of strain NEAU-383 could effectively prevent tomato bacterial wilt, and the biological control efficiency was 85.2% and 95.1%, respecti
