Cold stress restricts plant growth, development, and distribution. Understanding how plants transduce and respond to cold signals has long been a topic of interest. Traditional genetic and molecular analyses have identified C-repeat/DREB binding factors (CBFs) as key transcription factors that function in cold acclimation. Recent studies revealed the involvement of pivotal protein kinases and transcription factors in CBF-dependent signaling, expanding our knowledge of cold signal transduction from perception to downstream gene expression events. In this review, we summarize recent advances in our understanding of the molecular regulation of these core components of the CBF cold signaling pathway. Knowledge of the mechanism underlying the ability of plants to survive freezing temperatures will facilitate the development of crop plants with increased freezing tolerance.
冷胁迫限制了植物的生长、发育及分布。理解植物如何转换和响应冷信号一直以来都是科研工作者们十分感兴趣的问题。传统的遗传学和分子生物学分析已经鉴定了C重复结合因子CBFs作为关键的转录因子作用于低温适应。近来的一些研究揭示了一些重要的蛋白激酶及转录因子参与依赖于CBF的信号转导途径,拓宽了我们对于植物感知冷信号到下游基因表达的认知。本综述总结了近来关于CBF冷信号通路上关键组分的分子调控的理解。对于植物适应低温的潜在机制的理解有助于促进提升作物对于寒冷胁迫抗性的遗传改良。
