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 کاملEngineering Cold Stress Tolerance in Crop Plants
Plants respond with changes in their pattern of gene expression and protein products when exposed to low temperatures. Thus ability to adapt has an impact on the distribution and survival of the plant, and on crop yields. Many species of tropical or subtropical origin are injured or killed by non-freezing low temperatures, and exhibit various symptoms of chilling injury such as chlorosis, necro...
متن کاملCold stress: Manipulating freezing tolerance in plants
A single transcription factor can trigger induction of the freezing-tolerant state in Arabidopsis. Is such a factor all that is lacking in non-hardy plants?
متن کاملPhysiology and molecular biology of salinity stress tolerance in plants
The productivity of plants is greatly affected by various environmental stresses. Soil salinity affects plant growth and development by way of osmotic stress, injurious effects of toxic Na and Cl – ions and to some extent Cl – and SO4 2 – of Mg and nutrient imbalance caused by excess of Na and Cl – ions. Salinity stress response is multigenic, as a number of processes involved in the tolerance ...
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...
