As a result of climate change, crops often experience high-temperature stress that can drastically hinder plant growth and development. In soybean, an economically important crop is highly sensitive to heat stress, the use growth-promoting rhizobacteria (PGPRs) represents promising strategy for countering negative effects stress. Accordingly, novel strain Bacillus tequilensis (i.e. SSB07) grows actively at high temperatures was isolated, identified, characterized in present study. SSB07...
