Intraspecies differences in cold hardiness, carbohydrate content and β-amylase gene expression of Vaccinium corymbosum during cold acclimation and deacclimation.
Changes in cold hardiness, carbohydrate content and β-amylase gene expression were monitored in the shoots of the highbush blueberry (Vaccinium corymbosum L.) cultivars 'Sharpblue' and 'Jersey' during cold acclimation (CA) and deacclimation (DA). The seasonal patterns were similar in both cultivars, but the levels of cold hardiness determined by electrolyte leakage analysis were significantly d...
متن کاملTime-dependent deacclimation after cold acclimation in Arabidopsis thaliana accessions
During low temperature exposure, Arabidopsis thaliana and many other plants from temperate climates increase in freezing tolerance in a process termed cold acclimation. However, the correct timing and rate of deacclimation, resulting in loss of freezing tolerance and initiation of growth is equally important for plant fitness and survival. While the molecular basis of cold acclimation has been ...
متن کاملCell Wall and Extensin mRNA Changes during Cold Acclimation of Pea Seedlings.
During exposure to 2 degrees C, pea (Pisum sativum) seedlings cold acclimated to a killing temperature of -6 degrees C. Associated with this increase in freezing resistance was an increase in the weight of cell walls and changes in wall composition. Arabinosyl content increased by 100%, while other cell wall glycosyl residues and cellulose increased by about 20%. The cell wall hydroxyproline co...
متن کاملVariability in the Rate of Cold Acclimation and Deacclimation among Tuber-bearing Solanum (Potato) Species
Two major components of frost resistance are freezing tolerance in the nonacclimated state (growing in normal condition) and capacity to cold acclimate (increase in freezing tolerance upon exposure to chilling temperatures). In addition to these two major components, numerous factors contribute to frost survival. Although the rate of cold acclimation and deacclimation have been recognized as im...
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...
