水稻中金属元素转运机理与相关转运蛋白研究进展
Progress on the Mechanism of Metal Element Transport and Related Transport Proteins in Rice
摘要
Abstract
Zinc,iron,manganese,and copper are indispensable metal elements in plants and play a wide and crucial role throughout the plant's life cycle.While absorbing these essential metal elements,plants may also absorb some heavy metal elements that are harmful to them,such as cadmium.Cadmium often invades plant bodies by utilizing the transport pathways of essential elements such as iron,zinc,and manganese.It is easy to be transferred within plants and exhibits its toxicity by occupying the functional sites of essential elements in proteins,therefore it is considered a representative element for studying the absorption and transport patterns of non-essential elements in plants.Studying the molecular mechanisms of rice absorbing and transporting essential metal elements(such as zinc and iron)under conditions of excessive cadmium content is of great significance for cultivating rice varieties that are both rich in high-nutrient elements such as zinc and iron and have low cadmium accumulation.In this paper,we reviewed the effects of essential and non essential metal elements on the rice growth and development,and the mechanisms of absorption and transpotation of metal elements by rice(concluding transport proteins),and comprehensively summarized the relevant genes that plays a crucial role in the absorption and transport of Zn,Fe,Mn,Cu and Cd in rice,aiming to provide some references for cloning and utilizing these genes.关键词
