摘要: 植物细胞可能是通过细胞膜流动性的改变引起胞质Ca2+浓度变化来感受低温信号的。胞质Ca2+浓度升高引起胞内多种钙调节蛋白的活性变化,再经过级联反应激活冷反应基因,增强植物的抗低温能力。目前,已基本清楚,冷反应基因激活的一条主要途径是ICE1-CBF调节通路。概括介绍了近年来植物低温信号感受、转导、冷反应基因的表达激活和调节方面的研究概况,旨在为植物冷驯化的进一步研究奠定理论基础。

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
