Pseudomonas mosselii JP2-207 was isolated from the soil of the rhizosphere of rice plants, this strain showed obvious inhibitory activity against Ustilaginoidea virens, an important rice pathogen. The complete genome of P. mosselii JP2-207 consists of 5 702 443 bp with a circle chromosome, 5 154 protein-coding genes, 22 rRNA genes, and 78 tRNA. The genomic analysis revealed that 9 candidate gene clusters were involved in the biosynthesis of secondary metabolites. Together, this study provides preliminary results for exploring the antagonistic mechanism of rice false smut by P. mosselii JP2-207 and its secondary metabolites.
Key words： Pseudomonas mosselii; rice; rice false smut disease; metabolite; gene clusters; biocontrol
