Unveiling the complete genome sequence of Paenibacillus taichungensis: genomic features and biocontrol potential

The genus Paenibacillus encompasses a diverse group of Gram-positive bacteria with significant biotechnological potential. However, the research data and application cases of Paenibacillus taichungensis were still poorly understood. In this study, we isolated a P. taichungensis strain BB507, which demonstrated antibacterial effect on Ralstonia solanacearum species complex, and provided data and analysis of its complete genome.

Strain BB507 was isolated from a pine rhizosphere in Meizhou city, Guangdong province of China, and showed antibacterial activity against Ralstonia solanacearum species complex. Complete genome was sequenced using Illumina NovaSeq (second-generation) and Oxford Nanopore (third-generation) platforms. The genome of BB507 comprised of a 6,974,531 bp circular chromosome and a 352,197 bp circular plasmid, encoding a total of 6,649 gene with an average gene length of 950 bp, 103 transfer RNAs, 2 sRNAs, and 36 rRNAs. Three candidate CRISPRs, 6 genomic islands and 14 prophages were predicted. The bacterial orthologous average nucleotide identity (OAT) and the type genome server (TYGS) analysis highlighted the strain BB507 was clustered into a subgroup with P. taichungensis. antiSMASH v7.0 predicted the presence of 10 secondary metabolite gene clusters in the genome. These findings will serve as a useful resource for further research in industrial and agricultural biotechnology.
