ABSTRACT=<p><italic>Paenibacillus peoriae</italic> is a plant growth-promoting rhizobacteria (PGPR) widely distributed in various environments. <italic>P. peoriae</italic> ZBFS16 was isolated from the wheat rhizosphere and significantly suppressed grape white rot disease caused by <italic>Coniella vitis</italic>. Here, we present the complete genome sequence of <italic>P. peoriae</italic> ZBFS16, which consists of a 5.83 Mb circular chromosome with an average G + C content of 45.62%. Phylogenetic analyses showed that ZBFS16 belongs to the genus <italic>P. peoriae</italic> and was similar to <italic>P. peoriae</italic> ZF390, <italic>P. peoriae</italic> HS311 and <italic>P. peoriae</italic> HJ-2. Comparative analysis with three closely related sequenced strains of <italic>P. peoriae</italic> identified the conservation of genes involved in indole-3-acetic acid production, phosphate solubilization, nitrogen fixation, biofilm formation, flagella and chemotaxis, quorum-sensing systems, two-component systems, antimicrobial substances and resistance inducers. Meanwhile, <italic>in vitro</italic> experiments were also performed to confirm these functions. In addition, the strong colonization ability of <italic>P. peoriae</italic> ZBFS16 was observed in soil, which provides it with great potential for use in agriculture as a PGPR. This study will be helpful for further studies of <italic>P. peoriae</italic> on the mechanisms of plant growth promotion and biocontrol.</p>
