ABSTRACT Climate change, specifically high temperatures, can reduce soil moisture and cause hypersaline conditions, which creates an unsustainable agro‐production system. Microbial symbionts associated with plants relinquish stressful conditions by producing stress‐protecting substances. Melatonin is a signaling molecule for plants, but least known microbial their function in stress protection. Here, our study shows that the melatonin‐synthesizing Bacillus velezensis EH151 (27.9 ng/mL at 96...
