Drought tolerance in soybeans is critical for maintaining productivity under water-limited conditions. This study aims to elucidate the physiological, biochemical, and molecular mechanisms underlying drought tolerance in soybeans, integrating advanced breeding strategies to enhance crop resilience. Physiological aspects such as root morphology, aquaporins, osmotic adjustment, and stomatal regulation are examined to understand water uptake and retention. Biochemical defenses, including antioxidant systems, metabolic pathways, and membrane stability, are analyzed for their roles in stress mitigation. Molecular studies focus on gene expression, signal transduction, and omics approaches to identify key drought-responsive elements. Integrative systems biology, gene editing, and biotechnology are discussed for developing drought-tolerant varieties. Practical applications in breeding and field trials are highlighted, addressing environmental variability and stress management. The study concludes with future research directions, emphasizing novel genes, epigenetic regulation, and the challenges in translating research into practice. This comprehensive approach aims to improve soybean drought tolerance, contributing to food security and sustainable agriculture.
