Post-translational activation of CBF for inducing freezing tolerance

Plants can acquire increased freezing tolerance through cold-acclimation involving the ICE1-CBF-COR pathway. Recently, Lee et al. investigated a potential link between the functional activation of CBF and cellular redox state. We propose that redox-mediated CBF activation could be a hub of low temperature as well as light signaling in the cold-acclimation process.
