Abstract:
Wheat is a common grain crop that provides basic calories and protein to more than 80% of the world's population. Concerns about the impact of rising temperatures on wheat production have grown as a result of global climate change in recent decades. The main abiotic stresses limiting wheat yield are heat and drought. Heat stress disrupts the plant's vital physiological and biochemical processes. In the endosperm, high temperatures lower grain number, photosynthetic activity, chlorophyll content, and starch production. Heat stress accumulates reactive oxygen species, which cause significant oxidative damage to the crop. Heat shock proteins are produced quickly by plants to reduce the effects of heat stress. Heat tolerance is influenced by several features such as stay green, chlorophyll fluorescence, and canopy temperature. Knowledge of heat stress effect and tolerance at the physiological, biochemical, and morphological levels is critical for developing novel crop types that can cope with future climates.
