Biomechanical 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 کاملTemperature 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 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...
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...
