摘　要：

盐腺是泌盐盐生植物的重要表皮结构, 可将植物体内积累的过多离子直接排出体外而避免盐害。上个世纪90年代以前主要从盐腺超微结构和生理学方面研究泌盐机理, 近期的研究发现了大量与盐腺泌盐相关的结构和控制泌盐的关键基因, 揭示了盐腺泌盐的可能机制。本文重点论述近年来有关盐腺的结构、盐腺分泌的生理及分子机制方面的进展, 并对将来盐腺泌盐研究的几个问题提出了看法。

Abstract:

Salt gland is an important epidermal structure of recreto-halophyte, which can directly exclude excessive ions out of plants in order to avoid salt stress. Salt-tolerance mechanism was studied mainly from the two aspects before 1990s: salt gland ultrastructure and physiology. Recent studies revealed the structures of salt glands involved in salt secretion and the key genes participating in salt secretion. The mechanism of salt secretion may be explained. In this review, we discussed the progress in the study of salt gland structure, and the physiology and molecular mechanisms of salt secretion. Future prospects related to salt secretion are proposed.

Key words: salt gland; salt secretion of salt gland; salt gland structure; genes; salt secretion mechanism
