Identification of novel microRNAs for cold deacclimation in barley
Plant Growth Regulation, 2020Cold acclimation is crucial for the overwintering process of plants. Cold deacclimation is also important for plant survival in winter, which results in loss of freezing tolerance and initiation of growth. MicroRNAs (miRNAs) play crucial roles in regulating various physiological activities including cold response in plants.

Effect of Cold Deacclimation on Delayed Fluorescence of Spruce Needles
Zeitschrift Für Pflanzenphysiologie, 1983Summary Delayed fluorescence of chlorophyll in the time range of 3–18 ms was studied in intact spruce needles. The temperature dependence of delayed fluorescence was measured during cold deacclimation and after artificial dehardening of the frostresistant P. abies and the frost-susceptible P. schrenkiana.

Variations in Cold Resistance among Apple Cultivars during Deacclimation
Journal of Experimental Botany, 1985Coleman, W. K. 1985. Variations in cold resistance among apple cultivars during deacclimation.— J. exp. Bot. 36: 1159-1171. One-year-old vegetative twig samples from mature, bearing trees of nine apple cultivars were monitored over two years for their dormancy intensity and relative cold hardiness levels during the winter/spring deacclimation period ...

Enzyme changes during deacclimation of willow stem
Cryobiology, 1970Abstract Qualitative changes were found to occur for certain, but not all, enzymes studied during deacclimation in Salix cortex. Because of the possible involvement of esterases in lipid transformations during hardening and dehardening, changes in the isoesterase pattern were important.

Shivering and nonshivering thermogenesis in exercised cold-deacclimated rats
European Journal of Applied Physiology and Occupational Physiology, 1988Norepinephrine (NE)-induced increase in oxygen consumption (VO2) and colonic temperature (Tc) was greater in cold-acclimated rats housed at 4 degrees C for 4 weeks (CA) than warm-acclimated controls housed at 24 degrees C for 4 weeks (WA). On the other hand, shivering activity measured at 4 degrees C was less in CA than in WA, while propranolol ...

Blueberry cultivars with varying percentages of species ancestry (V. corymbosum L., V. angustifolium Ait., V. ashei Reade, V. darrowi Camp) were assayed in mid-February to determine initial bud hardiness, and rates of deacclimation under constant temperature conditions.

Effects of exercise detraining and deacclimation to the heat on plasma volume dynamics
European Journal of Applied Physiology and Occupational Physiology, 1986The effects of the discontinuation (DET) of an endurance training/heat acclimation (T/A) program on vascular volumes were studied in 16 adult males. Resting and exercise blood volume dynamics were examined prior to and during an exercise task performed after completion of T/A (CT1) and again at the end of DET (CT2).

AbstractGrape compound buds adapt to subfreezing temperatures in winter by supercooling, but the supercooling ability is thought to be lost upon formation of xylem connections between canes and buds. It was reported that compound buds of the Vitis vinifera variety ‘Chardonnay’ lack xylem cells in mid‐winter, and that vessels differentiate during ...
