A review of heat stress signaling in plants

Abstract

Abstract The threat and crisis of food due to global warming has a related with global climate change. The threat of a decline in food production in various countries by climate change triggers a long drought. The increase in temperature causes heat stress on the plant which has an impact on the decline in land quality and others. Heat stress is often defined as an increase in temperature for a certain period of time, which can cause irreversible damage to plants, which generally occurs at temperatures of 10-15°C above the threshold. Heat stress is a major factor limiting crop productivity and adaptation, especially when extreme temperatures coincide with the critical stage of plant growth. Heat stress is a major factor limiting crop productivity and adaptation, especially when extreme temperatures coincide with the critical stage of plant growth. Excessive heat can disrupt by denaturing enzymes and damaging metabolism so that changes occur in the morphological structure, phenology, physiology and molecular plants. The response to increase in temperature of 5-10° C, makes plants produce a unique protein called heat shock proteins (HSP). An increase in HSP production occurs when plants experience a sudden or gradual increase in temperature. HSP is released when the stress of exposed to plant. Under these conditions HSP is useful for protecting proteins and causes resistant plants. The resistance obtained by heat shock is different from the resistance obtained by rapid growth at moderately high temperatures. This difference is presumed by the presence of HSP responses induced by heat stress. The HSP can play a role as a sign of gene stress and activation and in regulating oxidation reactions in cells. Utilization of heat stress signaling in food crops breeding can be used to development Wheat Tolerance to High Temperature.
