In the early stages of exposure to cold temperatures, mobilization of fatty acids from WAT is also known to be a primary source for the activation of BAT rather than the breakdown of fat depot stored in BAT [24].
After 24 hours of exposure to cold, the number of expressed TFs was 993.
A transcript with similarity to CONSTANS-like 1 in Lolium perenne, a gene which has been reported to increase after extended periods of exposure to cold [ 36], had a profile of transcript abundance that echoed that of TaTOC1 and TaGI.
As my colleague Alexia Tsotsis wrote in her initial review of The Social Network, the movie was built around heavily dramatized controversy and the exposure of the cold, calculating (and fictional) Mark Zuckerberg.
Exposure to weeks of cold temperature accelerates the transition to flowering in a process called vernalization.
Since both genes are also upregulated upon cold exposure, we next investigated what the effect of cold exposure on these two genes was in mice of both sexes combined with GDX.
Furthermore, the exposure of apples to cold can be important for ensuring the ethylene climacteric and ripening proceeds fully [ 58].
However, no increase in GUS activity was observed after exposure of seedlings to cold or heat stress, NaCl or hydrogen peroxide.
Intriguingly, whereas 1 day of cold exposure did not affect Angptl4 expression, 10 days of cold exposure led to a marked reduction in Angptl4 mRNA.
The duration of cold exposure to establish these respective responses is different, such that a few days of cold exposure is sufficient to initiate cold acclimation [15], whereas several weeks are required for vernalization [16].
