Plant adaptability to climate change and drought stress for crop growth and production

Abstract Abiotic factors pose a significant constraint for food security and agricultural production worldwide, and the issue has been exacerbated by extreme and rapid climate change. Heat and drought are the most important limiting factors that have a significant influence on crop growth and production. For better management, it is critical to understand the biochemical, ecological and physiological responses to these stresses. Plant responses to these challenges may be divided into three categories: phonological, physiological and biochemical. This review gives a thorough description of plant adaptations towards drought and heat stress, with a particular emphasis on identifying similarities and variations. As a result of physical damage, biological disruption and biochemical abnormalities, suboptimal water supplies and unusual temperatures negatively impact crop development and yields. However, both of these stressors have a wide range of impacts and are thus complex to explain in terms of mechanics. More profound knowledge of how plants respond to various challenges can lead to more practical solutions and management. A distinctive aspect of the phenomenon is comparing fundamental behaviour with abiotic stresses.
