摘要
内皮层凯氏带是植物根中水分和离子径向运输的屏障。由于内皮层凯氏带的精细结构及化学性质等方面的研究难度较大,因此多年来进展缓慢。随着显微技术和鉴定方法的不断改进,对凯氏带的结构和功能的研究得以深入,但对其发育、化学成分及与抗盐胁迫的关系方面的报道还不多见。本文就凯氏带的结构发育、化学组成以及其在抗盐胁迫中的作用进行了综述,以期为内皮层凯氏带功能的进一步研究提供新的思路。
Endodermal Casparian strip is an apoplastic barrier for radial water and solution flow in plant roots.The investigations on fine structures and chemical properties of endodermal Casparian strip are difficult,so the understandings on these aspects are insufficient at present.Due to the continuous improvements in microscopic techniques and identification methods,investigations on structures and functions of Casparian strip have been significantly intensified.However,only a few investigations have been carried out on the resistive roles in case of salt stress.This paper reviewed current advancements in the investigations on Casparian strips in order to provide new ideas for further study.
