摘要/Abstract

摘要： 锌和铁是植物生长发育所必需的微量营养元素,在植物的光合作用、呼吸作用以及许多生化反应中起着非常重要的作用。植物体内锌铁处于平衡状态才能保证其正常的生长发育,而锌铁调控转运体ZIP对于锌铁吸收、转运及体内平衡的调节有重要作用。目前,对于植物中ZIP家族基因的研究有一定进展。对植物ZIP基因的表达、蛋白定位、酵母互补实验、过表达及基因敲除等研究结果进行综述,揭示了ZIP蛋白在植物发育过程中的作用。了解ZIP对于锌铁吸收、转运及体内平衡中的作用有助于通过转基因改良及常规育种将ZIP蛋白应用于农业生产上。

Abstract: Zinc and iron are essential micronutrients for plant growth and development,and they play important roles in photosynthesis,respiration and other biochemical reactions. The normal growth and development of plant are ensured while zinc and iron in plant are in balance. ZIP plays important role in the uptake and transport,as well as the homeostatic regulation of Zn/Fe. At present there are research progress achieved in the ZIP gene family in plants. ZIP genes expression pattern,subcellular localization,yeast complementation assay,ZIP gene overexpression and knock down are summarized,and the function of ZIPin plant growth and development are explored. In sum,insight into the function of ZIP in uptake,transport and homeostasis of zinc/iron may contribute to the application of ZIP in agricultural production through genetic modification and conventional breeding.
