| Outline of Final Research Achievements |
A transient increase in calcium ion concentration was observed, when plants are treated with cold stresses. Mechanosensitive calcium channel MCA is involved in this transient increase in calcium concentration. Moreover, MCA is also involved in low temperature stress responses.
In addition, calmodulin-like proteins, CML10 and CML12, are involved as factors linking calcium signal and low temperature signal. These CMLs interacts with ICE1, a important transcription factor for cold signaling, to regulated cold stress responses.
