Published: Nov. 4, 2019

Abiotic stresses arising from climate change negates crop growth and yield, leading to food insecurity. Drought causes oxidative stress on plants, excessive production of reactive oxygen species (ROS) due inadequate CO2, which disrupts the photosynthetic machinery plants. The use conventional methods for development drought-tolerant crops is time-consuming, full adoption modern biotechnology enhancement still regarded with prudence. Plant growth-promoting rhizobacteria (PGPR) could be used as an inexpensive environmentally friendly approach enhancing under environmental stress. various direct indirect mechanisms plant by PGPR were discussed. Synthesis 1-aminocyclopropane−1-carboxylate (ACC) deaminase enhances nutrient uptake breaking down ACC, thereby preventing ethylene accumulation, enable plants tolerate water exopolysaccharides produced also improves ability soil withhold water. osmolyte production, effective in reducing detrimental effects ROS. Multifaceted PGPRs are potential candidates biofertilizer lessen drought cultivated arid regions.
