Regulation of the transcriptome is necessary for plants to acquire cold tolerance, and cold induces several genes via a cold signaling pathway. The transcription factors CBF/DREB1 (C-repeat binding factor/dehydration responsive element binding1) and ICE1 (inducer of CBF expression1) have important roles in the regulation of cold-responsive gene expression. ICE1 is post-translationally regulated by ubiquitylation-mediated proteolysis and sumoylation. This mini-review highlights some recent studies on plant cold signaling. The relationships among cold signaling, salicylic acid accumulation and stomatal development are also discussed.
植物获得耐寒性需要调控转录组，低温通过冷信号通路诱导几个基因。转录因子 CBF/DREB1（C 重复结合因子/脱水响应元件结合 1）和 ICE1（CBF 表达诱导因子 1）在调控冷响应基因表达中起重要作用。ICE1 受泛素化介导的蛋白水解和 SUMO 化的翻译后调控。这篇综述强调了一些关于植物冷信号的最新研究。还讨论了冷信号、水杨酸积累和气孔发育之间的关系。
