Abstract
Drought stress, driven by climate change and exacerbated by global
warming and rainfall anomalies, poses significant threats to agricultural
productivity and food security. It leads to profound morphological,
physiological, and biochemical changes in plants, impacting growth and yield.
Traditional strategies for drought mitigation, such as water-efficient
irrigation and genetic engineering, face limitations due to technical
challenges and resource de mands. Endophytic bacteria, a subset of plant
growth-promoting rhizobacteria (PGPR), offer a promising, sustainable
alternative to improve plant drought tolerance. These microorganisms establish
symbiotic relationships within plant tissues, enhancing nutrient acquisition,
modulating phytohormones, scavenging reactive oxygen species (ROS), and
influencing gene expression to promote plant growth and stress resistance. This
paper explores the mechanisms by which endophytic bacteria improve drought
tolerance, including nutrient acquisition, stomatal closure regulation, osmotic
adjustments, and biochemical changes. Examples from various crop studies
demonstrate the potential of these bacteria to enhance drought resilience. The
findings highlight endophytic bacteria as a vital tool in sustainable
agriculture, offering solutions to mitigate the adverse effects of drought
stress while supporting global food security.
