摘　　要：盐胁迫是影响植物生长发育重要的环境因子之一,为了适应及抵御盐胁迫危害的逆境,作物自身会通过一系列变化来适应环境而作出相关性应激性改变,如宏观形态学、生理学改变、微观分子生物学变化等。转录调控是细胞内部调控网络中最重要的一个环节,WRKY转录因子响应并参与多种植物的生物和非生物胁迫。本综述从盐胁迫下作物形态结构的变化、盐胁迫对作物生理代谢的影响以及WRKY转录因子参与作物抗盐调控网络等方面文献,来汇总分析近年来拟南芥、水稻及其他种类植物应对胁迫的响应机制以及WRKY转录因子的功能,为提高园艺作物抗盐性生理作用及分子机制提供帮助,同时为作物抗盐栽培提供新思路。Salt stress is one of the most important environmental factors that affect plant growth and development.A series of complex morphological, physiological and molecular changes have taken place in response to salt stress. Transcriptional regulation is one of the most important links in the intracellular regulatory network. WRKY transcription factors respond to and participate in the biotic and abiotic stresses of many plants. In this paper, the changes of crop morphology and structure under salt stress, the effects of salt stress on crop physiological metabolism, and the effects of salt stress on crop yield were reviewed. In recent years, the function of WRKY transcription factors known in the stress response of Arabidopsis and rice as well as other plants has been summarized. It will be helpful for analyzing the physiological mechanism and molecular mechanism of salt-resistant crops, and provided theoretical guidance for crop salt-resistant cultivation.
