High-Quality Genome Resource of Bacillus subtilis N4, a Biological Control Agent Isolated from Phoebe bournei

Bacillus subtilis strain N4, an endophyte isolated from the healthy leaves of Phoebe bournei, possesses an excellent biocontrol effect against stem canker of P. bournei caused by Lasiodiplodia theobromae. To understand its biocontrol mechanism, we assembled a high-quality genome of N4 using a combination of second- and third-generation sequencing methods. The N4 genome contained one circular DNA chromosome of 4,218,183 bp length with 43.5% GC content and 11 secondary metabolite biosynthesis gene clusters, including genes for subtilomycin synthesis. This high-quality genome assembly and gene annotation resource will provide better insights into the biocontrol potential of B. subtilis strain N4 against stem canker of P. bournei.
