摘要:

盐碱胁迫会引起植物出现水分亏缺、细胞膜透性发生变化、代谢紊乱以及蛋白合成受阻等现象,导致作物减产或死亡,是植物生长发育过程中面临的非生物胁迫之一,寻找降低盐碱胁迫危害的有效方法和提高植物耐盐碱能力的策略,对盐碱地综合利用具有重要意义。本文归纳了近年来盐碱胁迫下植物遭受的危害和植物适应性机制最新研究,总结了植物响应盐碱的生理及分子机制,分析了盐碱胁迫下植物以积累渗透调节物质、增加抗氧化酶活性、离子区隔等为主要调控方式的生理机制和以信号传导、转录因子调控、耐盐碱相关基因表达等为主的分子机制,指出了植物适应盐碱环境方面的发展趋势和亟待解决的问题,以期为耐盐碱植物种质的筛选与培育提供一定的理论依据。

Abstract:

Saline-alkali stress is one of the abiotic stresses in the process of plant growth and development, which can cause water deficit, changes in cell membrane permeability, metabolic disorders and blockage of protein synthesis in plants, resulting in crop yield reduction or death. Finding effective methods to reduce the harm of saline-alkali stress and strategies to improve the saline tolerance of plants are of great significance to the comprehensive utilization of saline land. In this paper, the latest researches on the damage and adaptive mechanism of plants under saline-alkali stress in recent years were summarized, and the physiological and molecular mechanisms of plants responding to saline-alkali stress were summed up. Furthermore, the physiological mechanisms of plants under saline-alkali stress were analyzed, which were mainly regulated by accumulating osmotic substances, increasing the activity of antioxidant enzymes and ionic compartmentalization, etc., and the molecular mechanisms were mainly regulated by signal transduction, transcription factor regulation and the expression of plant salt-tolerance-related gene, etc. This study pointed out the trends and urgent problems in the development of plant adaptation to saline-alkali environments, with a view to providing a certain theoretical basis for the selection and cultivation of saline and alkali tolerant plants.
