Introducing specific plant growth-promoting bacteria can significantly mitigate the negative impacts of heat stress on soybean crops by enhancing physiological and biochemical defense mechanisms.

BMC Microbiology · 2020

Key Findings

01Bacillus cereus SA1 inoculation improved soybean biomass and chlorophyll content under both normal and heat stress conditions.
02SA1 inoculation led to a reduction in abscisic acid (ABA) and an increase in salicylic acid (SA) under heat stress.
03SA1 enhanced antioxidant enzyme activity (ascorbic acid peroxidase, superoxide dismutase) and increased amino acid and heat shock protein (HSP) content in soybean plants under heat stress.
04SA1 inoculation influenced the expression of stress-responsive genes (GmLAX3, GmAKT2).

Paragraph starter

Research by Khan et al. (2020) demonstrated that inoculating soybean plants with the thermotolerant bacterium Bacillus cereus SA1 significantly improved their resilience to heat stress. This was achieved by enhancing physiological factors such as chlorophyll content and biomass, and modulating biochemical pathways, including antioxidant defense and hormone regulation, leading to increased crop performance under adverse thermal conditions.
