Fusarium crown rot caused by Fusarium pseudograminearum is one of the most devastating diseases of wheat worldwide causing major yield and economic losses. In this study, strain YB-15 was isolated from soil of wheat rhizosphere and classified as Bacillus subtilis by average nucleotide identity analysis. It significantly reduced Fusarium crown rot with a control efficacy of 81.50% and significantly improved the growth of wheat seedlings by increasing root and shoot fresh weight by 11.4% and 4.2%, respectively. Reduced Fusarium crown rot may have been due to direct antagonism by the production of β-1, 3-glucanase, amylase, protease and cellulase, or by the ability of B. subtilis YB-15 to induce defense-related enzyme activities of wheat seedlings, both alone and in seedlings infected with F. pseudograminearum. Improved plant growth may be related to the ability of B. subtilis YB-15 to secrete indole acetic acid and siderophores, as well as to solubilize phosphorus. In addition, the genome of strain YB-15 was determined, resulting in a complete assembled circular genome of 4,233,040 bp with GC content of 43.52% consisting of 4207 protein-encoding genes. Sequencing the B. subtilis YB-15 genome further revealed genes for encoding carbohydrate-active enzymes, biosynthesis of various secondary metabolites, nutrient acquisition, phytohormone production, chemotaxis and motility, which could explain the potential of strain YB-15 to be plant growth-promoting bacteria and biological control agent. B. subtilis YB-15 appears to be a promising biocontrol agent against Fusarium crown rot as well as for wheat growth promotion. |
