摘　要：

非生物胁迫严重影响植物生长发育, 降低作物产量。植物通过各种途径忍受或抵抗非生物胁迫, 主要表现是各种抗 非生物胁迫基因的表达。基因表达受其上游启动子及转录因子的调控, 目前对抗非生物胁迫诱导启动子顺式作用元件及转 录因子的研究成为热点。本文综述了植物非生物胁迫诱导启动子顺式作用元件及转录因子的研究方法, 并展望了顺式作用 元件及转录因子研究的方向及前景。

Abstract:

Abiotic stress seriously affects plant growth and development, reduces crop yields. Plants endure or resist abiotic stress via many ways, mainly by expressing abiotic stress-induced genes. Gene expression is regulated by upstream promoter and transcription factors. Abiotic stress-induced promoter cis-acting element and transcription factors become one focus of study now. This paper reviews the research methods of plant abiotic stress inducible promoter cis-acting elements and transcription factors and looks into their prospect.

Key words: abiotic sterss; promoter; cis-acting elements; transcription factors
