Complete Genome Resource of a Fungal Antagonistic Strain: Pseudomonas tohonis

Abstract

The KRS022 was isolated from the rhizosphere soil of a healthy plant in a pathogen-infested cotton field in Xinjiang, China. Previous studies have demonstrated that KRS022 possesses the ability to trigger plant immune responses, inhibit the growth of various pathogenic fungi, including Verticillium dahliae, and promote plant growth. The antagonistic properties of KRS022 primarily stem from its bioactive metabolites. In this study, the high-quality genome of KRS022 was obtained. The KRS022 genome consists of a chromosome of 6,369,026 bp with 67.09% GC content, possesses 5,830 ORFs, of which 5,186 genes were annotated, and 119 ncRNA genes. Additionally, eleven gene clusters of secondary metabolites biosynthesis were predicted, involving in PKS, arylpolyene, NAGGN, betalactone, ranthipeptide, RIPP-like, redox-cofactor, and NRPS clusters. It could be useful to explore the biocontrol potential of P. tohonis, implying promising application of KRS022 in biological control.
