为了在盐碱环境中生存，盐生植物进化出了许多抵抗盐胁迫的策略。盐生植物的盐腺具有直接分泌盐分的特殊功能。了解盐分泌途径与盐腺功能的关系，可以帮助我们改变作物的耐盐性，并培养可利用的大面积盐碱地。近年来，盐腺的超微结构研究和盐分泌机制的研究，特别是与盐分泌有关的候选基因的研究，已经得到了详细的阐述。本文综述了盐腺结构、泌盐机制及相关候选基因的研究进展，并对盐腺泌盐途径和盐腺离子不对称转运进行了综述。并提出了一种新的模式盐生植物。
To survive in a saline environment, halophytes have evolved many strategies to resist salt stress. The salt glands of recretohalophytes are exceptional features for directly secreting salt out of a plant. Knowledge of the pathway(s) of salt secretion in relation to the function of salt glands may help us to change the salt-tolerance of crops and to cultivate the extensive saline lands that are available. Recently, ultrastructural studies of salt glands and the mechanism of salt secretion, particularly the candidate genes involved in salt secretion, have been illustrated in detail. In this review, we summarize current researches on salt gland structure, salt secretion mechanism and candidate genes involved, and provide an overview of the salt secretion pathway and the asymmetric ion transport of the salt gland. A new model recretohalophyte is also proposed.
