摘要： Bacillus spp. have been widely reported with the ability to control plant diseases. In this work, we analyzed the whole genome of LJBS06, which was isolated from grapevine rhizosphere soil. In view of physiological and biochemical characteristics, genome data, and phylogenetic analysis of 16S rRNA, LJBS06 was affiliated with Bacillus stercoris. LJBS06 showed antagonistic activities against a variety of plant pathogens. The inhibition rate of Magnaporthe oryzae was up to 75.05% and the inhibition rates of Colletotrichum gloeosporioides, Coniothyrium diplodiella, and Botrytis cinerea were all above 50% in the plate assays. The genome of LJBS06 had a 4,154,362-bp circular chromosome, with an average GC content of 43.96%, containing an 82,935-bp plasmid with a GC content of 35.18%. The circular chromosome of LJBS06 contained 4231 protein-coding genes, 30 rRNA genes, and 87 tRNA genes, including genes related to the synthesis of plant defense-related enzymes and the promotion of plant growth. Meanwhile, 11 gene clusters involved in biosynthesis of secondary metabolites were present in the genome of LJBS06. In conclusion, our findings indicated that LJBS06 strain had the necessary genetic machinery to control plant pathogens and provided insights for future studies of the biocontrol mechanisms of B. stercoris LJBS06.
