Thermodynamics of Abiotic Stress and Stress Tolerance of Cultivated Plants
Plants, as living systems, depend simultaneously on their internal status and their surroundings. Changes in plants’ surroundings, generated by different environmen‐ tal factors (abiotic stress), could perturb existing homeostasis, thus imposing stress. Abiotic stress includes heat, cold, freezing, flooding, drought (refers to water deficit), weak or strong light, oxygen deficiency or sufficien...
متن کاملIon Transporters and Abiotic Stress Tolerance in Plants
Adaptation of plants to salt stress requires cellular ion homeostasis involving net intracellular Na(+) and Cl(-) uptake and subsequent vacuolar compartmentalization without toxic ion accumulation in the cytosol. Sodium ions can enter the cell through several low- and high-affinity K(+) carriers. Some members of the HKT family function as sodium transporter and contribute to Na(+) removal from ...
متن کاملAbscisic Acid and Abiotic Stress Tolerance in Crop Plants
Abiotic stress is a primary threat to fulfill the demand of agricultural production to feed the world in coming decades. Plants reduce growth and development process during stress conditions, which ultimately affect the yield. In stress conditions, plants develop various stress mechanism to face the magnitude of stress challenges, although that is not enough to protect them. Therefore, many str...
متن کاملAbiotic Stress Tolerance in Plants: Myriad Roles of Ascorbate Peroxidase
One of the most significant manifestations of environmental stress in plants is the increased production of Reactive Oxygen Species (ROS). These ROS, if allowed to accumulate unchecked, can lead to cellular toxicity. A battery of antioxidant molecules is present in plants for keeping ROS levels under check and to maintain the cellular homeostasis under stress. Ascorbate peroxidase (APX) is a ke...
متن کاملCircadian regulation of abiotic stress tolerance in plants
Extremes of temperatures, drought and salinity cause widespread crop losses throughout the world and impose severe limitations on the amount of land that can be used for agricultural purposes. Hence, there is an urgent need to develop crops that perform better under such abiotic stress conditions. Here, we discuss intriguing, recent evidence that circadian clock contributes to plants' ability t...
