A plant universal stress-inducible regulatory element comprises 5′-flanking DNA sequences of a plant gene which exhibits induced synthesis in response to a variety of environmental stresses, e.g., heat shock, osmotic pressure, salt stress, heavy metal ion concentration, partial anaerobiosis, etc. The isolation, characterization and utility of such a regulatory element is disclosed. The plant universal stress-inducible regulatory element contains promoter functionality, associated with sites of initiation of transcription, as well as regulatory function associated with the induction response to a variety of stresses. Methods are provided for inducing an increased level of expression of plant-expressible genes in plant tissue in response to environmental stress.
一种植物通用胁迫诱导调控元件由植物基因的 5′-侧翼 DNA 序列组成,该基因在各种环境胁迫(如热休克、渗透压、盐胁迫、重金属离子浓度、部分无氧状态等)下表现出诱导合成。本文公开了这种调控元件的分离、表征和用途。植物通用胁迫诱导调控元件包含与转录起始位点相关的启动子功能,以及与各种胁迫诱导反应相关的调控功能。提供了诱导植物组织中植物可表达基因的表达水平提高以应对环境胁迫的方法。
