... to a genetic basis, mounting evidence suggests that there is standing genetic variation in various cold tolerance traits in insect populations. In D. melanogaster , there is evidence of clinal variation in chill coma recovery time ( Hoffmann et al., 2002 ), and this trait has been shown to evolve in response...

...Nicholas M. Teets; J. D. Gantz; Yuta Kawarasaki ABSTRACT Rapid cold hardening (RCH) is a type of phenotypic plasticity that allows ectotherms to quickly enhance cold tolerance in response to brief chilling (lasting minutes to hours). In this Review, we summarize the current state of knowledge...

...), in which mild chilling significantly enhances cold tolerance within minutes. 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...
