摘　　要：植物遭受盐胁迫时的重要反应就是体内产生大量的渗透调节物质：无机盐离子和可溶性有机化合物．大量研究证明，有机物是植物在盐境下最重要的渗透调节剂，它无毒，且对稳定细胞的结构和功能有重要的作用。对有关渗透调节剂的基因调控机制的最新进展作了综合论述．The plants show marked response to salt stress and produce two kinds of osmoticadjustment substances: inorganic salt ions and soluble organic substances. A lot of researches have peoved that the organic solutes are vital to osmotic adjustment in the plants under salt stress. These orgunic solutes are not ouly untoxic to plant, but also of great importance to stabilizing the cell' s structure and functions. The latest development of the mechanism concerning genic regulation of these osmotic-adjustment substances is also reported in this paper.
