To analyze the complete genome sequence of the Brevibacterium frigoritolerans ZB201705, a Brevibacterium strain was isolated from the maize rhizosphere in drought- and salt-stressed soil, and the activity of the strain under simulated drought and high salt conditions was assessed. We used a combination of the PacBio RS and Illumina sequencing platforms to obtain the complete genome sequence of B. frigoritolerans ZB201705. The genome consists of 5,475,560 bp in a linear chromosome with no gaps, 4,391 protein-coding sequences, 39 ribosomal RNAs, and 81 transfer RNAs. The genome analysis revealed many putative gene clusters involved in defense mechanisms. In addition, an activity analysis of the strain under high-salt and simulated drought conditions helped clarify its potential tolerance to these abiotic stresses. Our data revealed the complete genome sequence of the new isolated strain, and showed that it produces many proteins involved in drought and salt stress responses, suggesting that B. frigoritolerans ZB201705 may be a potential factor to increase crop yield under abiotic stresses. The information provided here on the genome of B. frigoritolerans ZB201705 provides valuable insight into rhizobacteria-mediated plant salt and drought tolerance and rhizobacteria-based solutions for agriculture under abiotic stress.
