Influence of cold acclimation on membrane injury in frozen plant tissue.
Cold-acclimated twigs of Amelanchier alnifolia Nutt. released less HCN at -4.5 C than nonacclimated twigs following slow freezing to -25 C or rapid freezing to -78 C. Cold-acclimated twigs frozen slowly to -25 C released more HCN than cold-acclimated twigs frozen only to -4.5 C. Cold-acclimated twigs frozen slowly to -25 C and then rapidly to -78 C released less HCN at -4.5 C than cold-acclimat...
متن کاملInfluence of low- and high-elevation plant genomes on the regulation of autumn cold acclimation in Abies sachalinensis
Boreal coniferous species with wide geographic distributions show substantial variation in autumn cold acclimation among populations. To determine how this variation is inherited across generations, we conducted a progeny test and examined the development of cold hardening in open-pollinated second-generation (F2) progeny of Abies sachalinensis. The F1 parents had different genetic backgrounds ...
متن کاملFuture Perspectives in Plant Biology Molecular Basis of Plant Cold Acclimation: Insights Gained from Studying the CBF Cold Response Pathway
For the 75th Anniversary Issue of Plant Physiology, I contributed an article (Thomashow, 2001) in which I highlighted recent advances in the identification of genes with roles in cold acclimation: the process whereby certain plants increase in freezing tolerance in response to low nonfreezing temperatures. At that time, about 20 Arabidopsis (Arabidopsis thaliana) genes had been identified as co...

متن کاملEffect of cold acclimation on GSH, antioxidant enzymes and lipid peroxidation in brown adipose tissue.
Cold acclimation increased the activities of superoxide dismutase, catalase, total and selenium (Se)-dependent glutathione peroxidases (GPx) and glutathione reductase by 2-4-fold in the brown adipose tissue (BAT) of cold-acclimated rats. Nevertheless, when expressed per unit protein, the antioxidant enzyme activities were unaltered. Sensitivity to lipid peroxidation and GSH levels both increase...
