| 摘 要： | 植物可以利用不同的机制来维持Na+稳态, 从而增强植物的抗盐性。这些机制包括: 限制Na+的内流; 增大Na+的外排; 减少Na+向地上部分的运输; 把进入地上部分的Na+分散到特殊部分(如老叶)或通过泌盐结构排出体外或通过韧皮部的再循环回到根部。本文简要介绍整株水平上Na+转运体与植物抗盐性的研究进展。

| Abstract: | Plants can maintain Na+ homeostasis to increase salt resistance by several mechanisms, which include limiting Na+ influx, strengthening Na+ efflux, lessening Na+ transport to the shoot, distributing Na+ of shoots to particular parts (e.g., old leaves), secreting Na+ outside the leaves by a salt-secreting structure or transporting Na+ to the root by phloem recirculation. This paper introduces advances in research into the roles of Na+ transportation in salt resistance of plants at the whole plant level. |
