Mechanism and Application of Plant Rhizospheric Bacillus sp. for Growth Promotion and Disease Prevention

Abstract In order to promote the development and application of environmental-friendly, efficient and safe beneficial Bacillus sp. preparations, the paper summarizes and systematically elaborates the colonization of Bacillus sp. in host plants and the mechanism of synergistic effect on disease prevention of host plants, further reviews the application of rhizospheric Bacillus sp. in promoting the growth of agricultural and forestry crops and controlling plant diseases, and prospects the scientific issues and application of plant rhizospheric Bacillus sp. in the future. [...]the chemotaxis of Bacillus sp. to plant secretions is necessary for plant-microbe interaction. 2.1.2 Motility. [...]biological nitrogen fixation, phosphorus solubilization, and production of siderophore promote the absorption of nutrients by host plants. [...]antibacterial compounds are produced to inhibit the growth of plant pathogens, induce the resistance of plants to pathogens, and improve the health level of host plants.
