Streptomyces catenulae XG40 is a biocontrol strain with antagonism to pathogens of pomelo black spot. In this study, the whole-genome sequence of S. catenulae XG40 was completed by the third generation sequencing platform PacBio Sequel. Three contigs were obtained, including one chromosomal DNA and two plasmid DNA. The total length of the genome sequencing was 9 772 324 bp with 70.58% GC content, and 8074 protein-coding genes were predicted which were accounted for 96.41% of all genes. Forty-six putative secondary metabolite biosynthetic gene clusters were found in the genome using the online antiSMASH software, among twenty-four PKS and NRPS, which were accounted for 52.17% of all gene clusters. Seven putative gene clusters showed 100% similarities to known gene clusters: desferrioxamin B, pristinol, neoantimyci, 2-methylisoborneol, nigericin, ectoine, geosmin gene clusters. Four putative gene clusters showed more than 80% similarities to known gene clusters: miharamycin A/B, SW-163C/E/F/G/UK-63598, gilvocarcin V, coelibactin. Clusters analysis showed that S.catenulae XG40 had certain ability of the biosynthesis of nigericin and gilvocarcin V with antibacterial activity. The analysis of synteny indicated that genome insertion, deletion, rearrangement and translocation happened among the genomes of S. catenulae XG40, S. rhizosphaericus DSM 41760, S. malaysiensis DSM 14702, melanosporofaciens DSM 40318 and S. himastatinicus ATCC 53653. This research would provide a theoretical basis for further discovering biocontrol potential of XG40 and the secondary metabolites for agricultural biological control.
