Cold Signaling and Cold Response in Plants
Plants are constantly exposed to a variety of environmental stresses. Freezing or extremely low temperature constitutes a key factor influencing plant growth, development and crop productivity. Plants have evolved a mechanism to enhance tolerance to freezing during exposure to periods of low, but non-freezing temperatures. This phenomenon is called cold acclimation. During cold acclimation, pla...
متن کاملCold Hardiness of Woody Plants
stresses caused by their freezing and thawing. A key difference between a hardy plant and a non-hardy plant is believed to be where the ice forms in freezing: inside the living cells or outside of them. If ice forms inside of cells, it is almost always fatal to them, and this is probably the principal cause of frost kill in non-hardy plants. Normally hardy tissue may be killed by moderate tempe...
متن کاملEvaluation of six cold-season turfgrasses responses to lead phytotoxicity for screening tolerant species
Lead (Pb) is one of the most hazardous heavy metal that caused serious problems for ecosystem at recent years. In this study, the effect of Pb on seed germination, incipient growth and antioxidant enzymes of six common used turfgrasses was investigated. The results showed that after implementation of different concentrations (0, 1000, 2000 and 3000 µM) of Pb, Agropyron elongatum exhibited the h...
متن کاملPlants in a cold climate.
Plants are able to survive prolonged exposure to sub-zero temperatures; this ability is enhanced by pre-exposure to low, but above-zero temperatures. This process, known as cold acclimation, is briefly reviewed from the perception of cold, through transduction of the low-temperature signal to functional analysis of cold-induced gene products. The stresses that freezing of apoplastic water impos...
متن کاملGenetic engineering of salinity-tolerant plants
olecular techniques such as recombinant DNA technology may ultimately have their most significant effect on agriculture. Recent advances raise the possibility of the development of new plant germplasm through the introduction of any gene from any organism into plants. Several leading laboratories have achieved the transfer and expression of bacterial and foreign plant genes in plant cells. Incr...
