Isolation and characterization of endophytic bacteria for controlling root rot disease of Chinese jujube.

摘要: Aim Fusarium oxysporum is the primary pathogen causing root rot disease that severely affects cultivation of jujube fruit in Xinjiang province China. The aim this study was to identify endophytic bacteria healthy organs could effectively suppress F. growth. Methods and results Different plant (leaves, twigs roots) were collected from Chinese cultivated southern bacterium Brevibacterium halotolerans JZ7 selected for its strong antagonistic activity growth-promoting characteristics. Gas-chromatography mass-spectrometry analysis showed acetoin, 2,3-butanediol fenretinide three dominant volatile organic compounds produced by strain JZ7. Fenretinide strongly suppressed spore germination vitro. Pot experiments colonized both roots rhizosphere soil significantly reduced level soil. Conclusion We demonstrated B. can be developed into a biological control agent combat Significance impact suggested strategy fully accordance with current principles sustainability.
