植物抗寒相关转录因子研究进展

Research progress in transcription factors of cold resistant plants

低温是影响植物生长和分布范围的一个重要的气象因子。随着全球气候变化影响,低温冻害已经成为植物生产中最重要的限制性环境因子之一。了解植物抗寒的分子机制,成为当前植物分子生物学与生理学的研究热点之一。作为重要的基因调控因子,转录因子在植物的抗寒过程中表现出至关重要的作用。目前研究的与抗寒有关的转录因子主要有AP2/EREBP、MYB、NAC、bZIP、WRKY、Zinc-finger等。该文综述了植物中与抗寒相关的六大类转录因子的结构、分类及抗寒功能的研究现状,并对它们之间的互作研究现状进行简单阐述,同时对抗寒相关领域的进一步研究进行了展望。

Abiotic stress such as drought, high salinity and extreme temperatures have adverse effects on growth and production of land plants. Low temperature is one of the most important environment stresses that limits plant growth, sur-vival and geographical distribution. As the unstable global climate changes, low temperature has become a major restrictive factor to land plants. As important gene regulation factors, transcription factors play crucial roles in cold resistance in plants. The AP2/EREBP, MYB, NAC, bZIP, WRKY and Zinc-finger transcription factors have been highlighted in cold resistance in plants. This paper reviewed the structures, classifications and functions of these six kinds of transcription fac-tors, and briefly presented their interactions. Some deep researches prospected in this area were also put forward.
