Climatic changes lead to various abiotic stresses around the world, causing global food insecurity. Among all the abiotic stresses, water stress is one of the chief constraints for plant health. Water stress causes oxidative stress by producing excessive reactive oxygen species (ROS), thereby affecting the physiological process which leads to the death of plant cells. So there is a need to improve the water stress ability of the plant in stressed conditions. Modern conventional method such as drought-tolerant crops could be adopted in drought prone areas but their implementation is time-consuming and prudent. Therefore, microbiological communities such as plant growth-promoting rhizobacteria (PGPR) have numerous eco-friendly bacteria associated with roots are gaining awareness by enhancing the stress tolerance ability of plants in abiotic stresses. PGPR act as biofertilizer and mitigate water deficiency by influencing the antioxidative enzyme activity and removing the ROS. Their role as bio-inoculants improves the water holding capacity and decreases the effect of water stress in arid areas with low water accessibility. This chapter deals with the usage of PGPR to boost plant water stress tolerance and agricultural sustainability. |
