<i>Bacillus altitudinis</i> GG-22: A novel plant growth-promoting bacterium with beneficial agronomic properties.

ABSTRACT: Bacillus altitudinis GG-22, isolated from the phyllosphere of agricultural crops, has been identified as a promising biocontrol agent and plant growth-promoting bacterium with substantial potential in sustainable agriculture. In this study, whole-genome sequencing using Illumina technology, combined with ANI analysis, confirmed the strain's classification as B. altitudinis. The genome revealed a rich set of genes involved in biocontrol mechanisms, including the capacity of synthesis of siderophores (schizokinen and bacillibactin-like compounds), the lipopeptide pumilacidin, the bacteriocin pumilarin, alkylpyrones and Bacillus volatiles. In vitro antagonism assays demonstrated significant inhibitory effects against phytopathogenic fungi and oomycetes, such as
