Identification of Leaf Proteins Differentially Accumulated between Wheat Cultivars Distinct in Their Levels of Drought Tolerance
The drought-tolerant 'Ningchun 47' (NC47) and drought-sensitive 'Chinese Spring' (CS) wheat (Triticum aestivum L.) cultivars were treated with different PEG6000 concentrations at the three-leaf stage. An analysis on the physiological and proteomic changes of wheat seedling in response to drought stress was performed. In total, 146 differentially accumulated protein (DAP) spots were separated an...
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...
متن کاملProteomic Analysis of Differentially Accumulated Proteins in Cucumber (Cucumis sativus) Fruit Peel in Response to Pre-storage Cold Acclimation
Harvested fruits are still living organs and respond to environmental stimuli. Low temperature storage is effective in extending life of harvested fruit, but it may also cause chilling injury. Cold acclimation has been shown to induce chilling tolerance in plants, but what proteomic changes caused by cold acclimation are related to defense against chilling stress remains largely unclear. Here, ...
متن کاملAdenine Nucleotide Changes during Cold Acclimation of Winter Rape Plants.
During the first stage of hardening of winter rape plants (Brassica napus L. var. oleifera L., cv. Górczański), marked increase of ATP content in leaves was observed. Lowering the temperature from 5 to 0 C (the second stage of hardening) had no further effect on ATP content. In roots, not capable of hardening, pronounced decrease of ATP content was noted after prolonged exposure to cold. It was...
متن کاملVernalization Requirement and the Chromosomal VRN1-Region can Affect Freezing Tolerance and Expression of Cold-Regulated Genes in Festuca pratensis
Plants adapted to cold winters go through annual cycles of gain followed by loss of freezing tolerance (cold acclimation and deacclimation). Warm spells during winter and early spring can cause deacclimation, and if temperatures drop, freezing damage may occur. Many plants are vernalized during winter, a process making them competent to flower in the following summer. In winter cereals, a coinc...
