<i>Bacillus amyloliquefaciens</i> G02 enhances selenium uptake in lettuce (<i>Lactuca sativa</i>) by improving soil selenium availability and rhizosphere microbiome regulation.

ABSTRACT: Selenium (Se) is an essential trace element for human, but its low availability in soils results in its inadequacy in edible crops, thereby limiting its human intake. However, the role of the plant growth-promoting bacteria in soil Se availability and the pathways involved in biofortification in edible plants remain poorly understood. In this study, a Se-tolerant, plant growth-promoting bacterium, Bacillus amyloliquefaciens strain G02, which activates Se was isolated from the soils in Se-rich fields in Guangxi, China. We employed soil microcosm and potted experiments, along with metabolomics and 16S rRNA sequencing, to investigate how strain G02 incubation promotes elemental Se (0) solubilization, soil Se activation, and Se enrichment in lettuce. The strain G02 exhibited high phosph
