Plants use the cytosolic transient Ca2+ concentration change as a kind of signal to regulate gene expression in cold acclimation process. We developed the experimental system for observation of Ca2+ signal during cooling, and observed Ca2+ signal to understand “how plants sense cold and seasonal changes.” We found several characteristics of Ca2+ signal and cold sensing. For example, plants adjust the Ca2+ signal to the ambient temperature to response small temperature decrease, and then small temperature fluctuation induces the cold-inducive transcription factor DREB1/CBFs expression via Ca2+ signals.}, pages = {98--101}, title = {植物の低温感知と馴化の制御:植物の冬季感知の理解に向けて}, volume = {60}, year = {2020} }
