摘要: 植物生长过程中不可避免的要面对不利的环境因素,它们已经进化出了灵活的基因表达重编程机制应对干旱、高盐、冷、热或洪涝等非生物环境胁迫。近年来,随着表观遗传学研究的不断深入,发现组蛋白翻译后修饰特性会受环境胁迫的影响而改变,启动相关胁迫应答基因表达,或者充当胁迫应答转录因子的下游参与调控转录活动,组蛋白修饰已经被证实在植物逆境的响应过程中起着至关重要的作用。主要综述了非生物胁迫下植物组蛋白修饰参与基因转录应答的最新进展,以期为植物非生物胁迫耐受性的相关研究提供参考。

Abstract: It is unavoidable to suffer from adverse environment in the process of plant growth. Hence they have evolved a flexible mechanism for reprogramming gene expression to cope with abiotic stresses such as drought,high salinity,cold,heat or submergence. Recently,along with the intensive studies of epigenetics,histone modification has demonstrated to play a crucial role under abiotic stress in plant. The properties of histone modification after translation can be altered by environmental stress,which initiates the expressions of abiotic stress-responsive genes,or act as a downstream factor to participant in the transcriptional regulation. In this review,we summarize the existing information about histone modification involved in the transcriptional regulation of abiotic stress-responsive genes,which is expected to provide a reference for the research on abiotic stress tolerance of plants.

Key words: histone modification, abiotic stress, stress response, transcriptional regulation of genes
