Temperature regulation and cold acclimation.
The questions concerned with temperature regulation raise sufficient controversy in themselves so that little but valor or foolishness can be attributed to one who chooses to discuss this subject in the furor of a second controversy acclimatization. However, I should like to introduce the papers of this session with a summary and a synthesis of the data with respect to control of metabolism and...
متن کاملTemperature sensing and cold acclimation.
The fundamental question in cold acclimation is how do plants perceive the low but nonfreezing temperatures that activate cold acclimation responses. New findings in the past year suggest that changes in membrane fluidity, cytoskeleton rearrangement, and calcium influxes are among the earliest events taking place in plants upon exposure to low nonfreezing temperatures. In the cyanobacterium Syn...
متن کاملBiomechanical Acclimation: Flying Cold
Why are animals reared at colder temperatures larger? A new study shows that fruit flies reared at lower temperatures are better able to fly in the cold.
متن کاملEffect of adrenaline and nor adrenaline on isolated rat ureter preparations.
The effect of adrenaline and nor-adrenaline on the spontaneously contracting and quiescent isolated proximal and central pieces of ureters obtained from female (virgin) albino rats of the Sprague Dawley strain were studicd, Adrenaline and nor-adrenaline produced a stimulant effect on the rate and amplitude of the proximal pieces of spontaneously contracting preparations. Both these drugs induce...
متن کاملCold Acclimation of Hedera helix
The light-enhanced production and accumulation of sugars is only one step in the process of cold acclimation in Hedera helix L. var. Thorndale (English ivy). Applications of 2,4-dinitrophenol to plants with different portions exposed to light and dark indicated that the mere presence or accunmulation of the light-generated promoters did not invoke an increase in hardiness. Kinetics of cold accl...
