Strain TSO22 was isolated from bulk soil associated with wheat crops in the Yaqui Valley, Mexico. The draft genome contained 4,294,671 bp, 43.7% G + C content, 731,759 bp N50, 3 L50, and 29 contigs. Based on 16S rRNA gene sequencing, the overall genome relatedness index, and phylogenomic relationship, strain TSO22 is highly affiliated with Bacillus inaquosorum. Genome annotation revealed 94 RNAs and 4,465 predicted coding DNA sequences distributed in 336 subsystems, in which genes involved in plant growth promotion and biocontrol were detected, such as colonizing plant system, competitive exclusionist, control of biotic and abiotic stresses, and plant immune response stimulation. Genomic predictions were confirmed through in vitro analysis, which revealed that B. inaquosorum TSO22 has great biological control against Bipolaris sorokiniana, as well as excellent metabolic capabilities to improve plant growth and development.
