英文摘要	A marine-sediment sample-derived strain Bacillus velezensis SH-B74 has the capacity to produce cyclic lipopeptides (CLPs), and these CLPs secreted by the strain show biological activities against various pests under both in vitro and in planta conditions, such evidence has supported that the strain SH-B74 is a biopesticide. To get a better insight into the mechanisms on the control of the pesticides by the strain, a genome sequencing project has been applied to the genomic DNA of the strain SH-B74. The results show that the strain SH-B74 has a chromosome size of 4,042,190bp, with a GC content of 46.5%, in addition, the strain contains a 61,634bp plasmid pSH-B74, with a GC content of 40.8%. Data from bioinformatic analysis reveal that the strain SH-B74 has genes with the capacity to increase environmental adaptation, promote the rhizosphere fitnesses and secrete a spectrum of antibiotics, including nonribosomal peptide synthetases (NRPSs)-derived CLPs bacillopeptin, plipastatin, and surfactin. The presence of CLPs in the bacterial cultures of the strain SH-B74 was confirmed further by LC-MS analysis. Thus, genome sequencing and analyses together with chemical analysis reveal the promising perspectives of the strain SH-B74 that are of spectacular importance to its trait as a plant beneficial microbe to be used in agriculture practices.
