| 为了解植物对低温胁迫响应机制的研究现状，以“低温胁迫”、“CBF”、“抗寒性”为关键词，在Web of Science核心合集、SpringerLink与中国知网等数据库就2000—2022年已发表的文献进行检索，对研究植物低温胁迫响应机制的相关文献进行总结和分析，结果表明:1)研究植物对低温胁迫的响应机制有助于为提升植物低温抗性提供依据，对应对全球复杂气候变化有重要意义；2)植物发生低温胁迫时，生物膜系统会遭到损伤，细胞渗透调节物质含量会发生变化以维持正常渗透压，而抗氧化酶的活性一般会呈现先上升后下降的趋势；3)植物有一套复杂信号通路响应机制来抵御低温胁迫，CBF途径可以通过对一些关键蛋白的翻译后修饰来调控植物对低温胁迫的抵抗，在植物抵御低温胁迫时发挥重要作用；4)关于CBF不依赖途径、低温信号感受器和低温信号分子的研究仍有待深入。 |

| Abstract: |
| In order to understand the research status of the response mechanism of plants to low temperature stress, the literature published from 2000 to 2022 were searched in Web of Science Core Collection, SpringerLink and China National Knowledge Infrastructure(CNKI)with “low temperature stress”, “CBF” and “cold resistance” as keywords. The literature related to the research on the response mechanism of plant to low temperature stress were reviewed and analyzed. The results showed that: 1)The study on the response mechanism of plants to low temperature stress is helpful to provide a basis for improving plant low temperature resistance, which is of great significance for coping with complex global climate changes; 2)When plants suffer from low temperature stress, their biofilm system will be damaged, the content of cell osmotic adjustment substances will also change to maintain normal osmotic pressure, and the activity of antioxidant enzymes will generally increase first and then decrease; 3)Plants have a complex and precise signaling pathway to resist low temperature stress. CBF-dependent pathway can regulate the low temperature resistance of plants through post-translational modification of some key proteins, and play an important role in plants resisting low temperature stress; 4)The research on CBF-independent pathways, low temperature signal receptors and low temperature signal molecules still needs to be further studied. |
