摘要
低温胁迫是植物生长过程中的主要非生物胁迫因子之一,也是影响农作物生产的主要因素之一。研究表明,在植物体内存在着一个复杂的对低温胁迫信号感知及传导的网络系统,该系统中大量的相关基因已有报道,这些基因不仅仅涉及植物激素的应答,还涉及到植物基因的转录调控及转录后的修饰与调控等各个方面。该文就近年来国内外有关植物抗寒基因表达调控的研究进展进行综述。
Cold stress is a major abiotic stress factor during plant growth and it is also one of the main fac-tors affecting the production of crop. In recent years, studies on cold tolerance of plants have shown that there is a complex signal network responding to low temperature stress in plant. Many related genes wet reported in this genetic regulatory network system. Not only plant hormones are involved in the response but also the gene transcription, even the posttranscriptional gene regulation. In this paper, recent advance on cold-resistant gene are regulated of plants are highlighted.
