The article "Plant Drought Stress: Effects, Mechanisms and Management" by M. Farooq, A. Wahid, N. Kobayashi, D. Fujita, and S.M.A. Basra reviews the impacts of drought stress on plant growth, phenology, water and nutrient relations, photosynthesis, assimilate partitioning, and respiration. Drought stress reduces leaf size, stem extension, and root proliferation, disrupts plant water relations, and decreases water-use efficiency. Plants respond to drought stress through various physiological and biochemical mechanisms, including stomatal closure, membrane damage, and altered enzyme activity. The article also discusses management strategies such as mass screening, breeding, marker-assisted selection, and exogenous hormone application to enhance drought tolerance. Key mechanisms of drought resistance include reduced water loss through increased diffusive resistance, enhanced water uptake with deep and prolific root systems, and smaller, succulent leaves to reduce transpiration. Nutrients like potassium ions and silicon play crucial roles in osmotic adjustment and improving cell water balance. Polyamines, citrulline, and certain enzymes act as antioxidants to mitigate the adverse effects of water deficit. At the molecular level, drought-responsive genes and transcription factors, such as dehydration-responsive element-binding genes and aquaporins, have been identified. The article emphasizes the importance of understanding these mechanisms to develop effective strategies for managing drought stress in crops.The article "Plant Drought Stress: Effects, Mechanisms and Management" by M.
