Recent studies have revealed the complex and flexible transcriptional regulatory network involved in cold-stress responses. Focusing on two major signaling pathways that respond to cold stress, we outline current knowledge of the transcriptional regulatory network and the post-translational regulation of transcription factors in the network. Cold-stress signaling pathways are closely associated with other signaling pathways such as those related to the circadian clock, and large amounts of data on their crosstalk and tradeoffs are available. However, it remains unknown how plants sense and transmit cold-stress signals to regulate gene expression. We discuss recent reports on cold-stress sensing and associated signaling pathways that regulate the network. We also emphasize future directions for developing abiotic stress-tolerant crop plants.

最近的研究揭示了参与植物中低温胁迫响应的、复杂而又灵活的转录调控网络。作者在本文中重点关注了植物响应低温胁迫的两个主要信号通路，回顾了目前对于转录调控网络和网络中相关转录因子的翻译后调控最新研究进展。低温胁迫信号转导通路与其他信号转导通路密切相关，例如其就与生物钟相关的信号转导通路较为相关，目前的研究报道了大量关于这两个信号转导通路之间的串联以及相互平衡的数据。然而，植物是如何感知和传递低温胁迫信号，从而来调节基因表达的，这一问题尚不清楚。作者在本文中还讨论了最近关于低温胁迫感知及其相关信号转导通路的报道。作者在本文中重点突出了关于未来开发非生物胁迫抗性作物的方向。
