Some species of Burkholderia have been studied extensively for their ability to control plant diseases and promote plant growth. Burkholderia gladioli KRS027 is a strain isolated from the rhizosphere soil of a healthy plant in a pathogen-infested cotton field in Xinjiang, China, which had an inhibitory ability against various plant-pathogenic fungi. To understand its biocontrol mechanism, we assembled a high-quality genome of KRS027 using the PacBio-HiFiReads. The KRS027 genome contained two circular DNA chromosomes and one plasmid, of which Chr1 contained 4,187,756 bp with 67.95% GC content, Chr2 had 3,892,275 bp with 68.56% GC content, and the plasmid comprised 177,327 bp with 61.11% GC content. Moreover, the genome contains 20 secondary metabolite biosynthesis gene clusters involving polyketides (PKS), nonribosomal peptides (NRPS), hybrid NRPS/PKS, and terpene. The genes involved in biosynthesis of phytotoxins, such as toxoflavin, rhizotoxin, and bongkrekic acid, were not detected. The high-quality genome resource of strain KRS027 will provide a molecular basis for further research on its biocontrol mechanisms. [Figure: see text] Copyright © 2023 The Author(s).
