摘　　要：植物基因的表达调控是一个复杂且精准的网络系统,一般包括转录水平和翻译水平二个层次。转录水平的调控发生在基因表达的初期,是许多基因表达调控的主要方式。在此调控过程中,被称为转录因子的蛋白质特异结合到靶基因的顺式作用元件上,控制着一系列相关基因的表达,在植物生长发育、物种起源和逆境胁迫应答过程中起着非常重要的作用,是生物遗传多样性的重要遗传基础。由于转录因子的重要作用,人们对其作用机理的理解也日渐深入。根据近期的研究进展,本文就转录因子在植物驯化、生物和非生物逆境胁迫方面的工作进行概括梳理,希望读者对此领域有一个比较深入和系统的认识,同时也能为挖掘具有关键功能的转录因子,提高重要农作物的遗传改良效率提供借鉴。Plant gene expression regulation is a complicated and accurate network generally including both transcriptional and translational regulation. In the process of transcriptional regulation, which mainly occurs in the early stage of regulating gene expression, the proteins called transcription factors specifically combine the cis-acting target elements and regulate a series of downstream relevant genes expression, playing an important role in plant development, evolution and environmental stress. It is therefore the genetic basis of biological diversity. Due to the important function of transcription factors, the understanding of its mechanism attracts more attention in recent years. In this manuscript, the latest development of transcription factors function in plant domestication, biotic and abiotic stress are reviewed, providing readers with deeper understanding of this field. It is also hoped to pave the road for mining more key genes and consequently improving the efficiency of genetic transformation with crops.
