Abstract
Bacillus subtilis TY-1 was isolated from 2000m-deep sea sediments of the Western Pacific Ocean, which was found to exhibit strong antagonistic activity against tobacco bacterial wilt caused by Ralstonia solanacearum. Here, we present the annotated complete genomic sequence of the strain Bacillus subtilis TY-1. The genome consists of a 4,030,869-bp circular chromosome with a G+C content of 43.88%, 86 tRNAs, and 30 rRNAs. Genomic analysis identified a large number of gene clusters involved in the biosynthesis of antibacterial metabolites, including lipopeptides(surfactin, bacillibactin, and fengycin) and polyketides(bacillaene). Meanwhile, numerous genes encoding carbohydrate-active enzymes and secreted proteins were found in TY-1. These findings suggest that Bacillus subtilis TY-1 appears to be a potential biocontrol agent against tobacco bacterial wilt in agricultural fields.
