MAPping Kinase Regulation of ICE1 in Freezing Tolerance

Mitogen-activated protein kinase (MAPK) signaling has important roles in plant stress responses. Two recent reports showed how MAPK signaling regulates the response to cold stress through the Inducer of CBF expression 1 (ICE1)-CBF-cold-responsive (COR) transcriptional pathway in Arabidopsis thaliana, expanding our understanding of cold stress signaling and regulation in plants.
