摘要: Aim The aim of this study was to identify efficient plant-beneficial rhizobacterium that has the potential be developed as biocontrol agent for control wheat soil-borne diseases. Methods and results Rhizosphere soil samples were collected from a field located in Taian City. Numerous bacteria isolated screened antagonistic activity against plant pathogenic fungi by performing dual-culture assays. Among them, XH-9 selected its highly others growth-promoting characteristics. Subsequently, strain identified Bacillus amyloliquefaciens subsp. plantarum based on phylogenetic analysis 16S rDNA sequence. Pot experiment indicated good capacities wheat, corn, chili root colonization considerably increased biometric parameters seedlings. Quantitative real-time polymerase chain reaction experiments showed amount Fusarium oxysporum associated with after treatment significantly decreased compared group. Conclusions when applied local arable land prevent damage caused F. other phytopathogens. Significance impact development strategies reducing pathogens is fully accord current principles sustainability.
