摘要

Abiotic stresses, including drought, salinity, extreme temperatures, and heavy metal toxicity, threaten global agricultural productivity and food security. These environmental challenges negatively impact plant growth, development, and production because they interfere with physiological and biochemical processes. Maintaining agricultural productivity amidst climate change requires enhancing plant resilience to these challenges. We highlight the myriad mechanisms that underlie plant responses to abiotic stress, including antioxidant defense systems, hormone control, transcriptional reprogramming, and signal transduction pathways. Advances in molecular biology, and omics technologies have provided deeper insights into stress-responsive genes and regulatory networks that govern adaptive traits. Recent developments have also shown potential in enhancing stress tolerance, including transgenic techniques, CRISPR/Cas-mediated genome editing, and the use of bio-stimulants, including melatonin, salicylic acid, and plant growth-promoting rhizobacteria (PGPR). Stress-resilient cultivars are being developed more quickly because of integrated breeding programs that combine high-throughput phenotyping and marker-assisted selection. New opportunities for sustainable crop enhancement are presented by the cooperative use of cutting-edge technologies and traditional knowledge. In harsh conditions, agricultural resilience and output can be improved by understanding and modifying the dynamic responses of plants to abiotic stresses. This review offers a thorough summary of the main physiological and molecular reactions, existing tactics, and potential future developments in improving plant resistance to abiotic stresses.
