摘要:

锌(Zn)是动物植物所必需的微量营养素,缺锌或锌过量会严重影响水稻的生长发育。水稻锌含量维持在一定范围有助于提高其产量和品质,并且可以提高籽粒的锌含量,一定程度上可以解决目前人体缺锌的问题。因此研究水稻锌的吸收、转运和分配,和其他调控锌稳态分子机制至关重要。基于近年来国内外研究报道,简要概述了锌在植物体内的重要性,重点介绍了水稻中的离子转运体和目前已经报道的分子机制。总结了这些离子转运体参与了锌从土壤的吸收,从根部向地上部的转运,以及分配到水稻各部位,还总结了一些和离子转运体相关的分子机制。以期为水稻锌稳态调控基因的挖掘、分子机制的研究和富锌水稻种质的创制提供参考。

Abstract:

Zinc (Zn) is an essential micronutrient for animals and plants. Zinc deficiency or excess can seriously affect the growth and development of rice. Maintaining zinc content in rice at a certain level is helpful to improve the yield and quality of rice, increase the zinc content in grain, and solve the current problem of zinc deficiency in human body to a certain extent. Therefore, it is important to understand Zn uptake, transport, distribution, and other molecular mechanisms regulating Zn homeostasis in rice. In this review, we briefly summarized the importance of zinc in plants, especially the ion transporters in rice and the molecular mechanisms. The roles of these ion transporters in the uptake of Zn from soil, the transport from root to shoot, and the distribution of Zn to various parts of rice were summarized. Some molecular mechanisms related to ion transporters were also summarized. This study provides reference for the mining of zinc homeostasis regulatory genes in rice, the study of molecular mechanism, and the creation of high zinc rice germplasm.
