Abstract: Cold stress signal is sensed while changes of cell membrane fluidity in plant cells cause the changes of Ca2+ influx. The rising of Ca2+ in cytoplasm leads to the changes of activities of various calcium-regulating proteins in plant cells, then cold-responsive genes are activated by cascade reactions, and thus plant resistance to low temperature is enhanced. At present, it is almost certain that the main path of activating cold-responsive genes is ICE1-CBF regulatory pathway. In this paper. We review the recent studies of the cold signal sensing and transduction, expression activation and regulation of cold-responsive genes in plant cells, which lays the theoretical foundation for the further study of cold acclimation of plants.

Key words: plants, cold-responsive genes, signal transduction, regulation of gene expression
