For chill-susceptible insects, such as Drosophila , cold tolerance is tightly linked to ion and water homeostasis obtained through a regulated balance of active and passive transport. Active transport at low temperature requires a constant delivery of ATP and we therefore hypothesize that cold...

...Nicholas M. Teets; J. D.

In this Review, we summarize the current state of knowledge...

While the ecological significance of RCH is well established, the mechanisms underlying RCH are still poorly understood. Previous work has demonstrated that RCH is regulated at the cellular level by post-translational signaling...

The accumulation of the Frost ( Fst ) gene transcript increases after cold exposure, making it a good candidate for a gene that has a role in cold tolerance.
