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 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 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 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 کاملGene regulation during cold acclimation in plants
doi: 10.1111/j.1399-3054.2005.00596.x Cold acclimation involves precise signaling and regulation of the transcriptome. The plasma membrane may be the primary cold-stress sensor, and FRY1/HOS2 inositol polyphosphate 1-phosphatase regulates cytosolic inositol-1,4,5-triphosphate levels, which in turn control cytosolic Ca2þ signatures and cold acclimation. Cold-induced reactive oxygen species may a...
