Abstract: Zinc and iron play virtual roles in plants development and involve in many biological functions. Zinc and iron deficiency or excess will cause harmful effects to plants. Therefore, metal transporters are essential for maintaining ion homeostasis. These metal transporters were classified into two groups, metal-uptake proteins and metal-efflux proteins. They are involved in the transmembrane-transporting and translocation of the intracellular zinc and iron, and regulating the homeostatic of zinc and iron. At present, many metal transporters have been identified and their expression profiles associated with zinc/iron accumulation and distribution have been described. The gene expression and protein localization of those zinc/iron-transporter families were reviewed in this article.

Key words: Zinc, Iron, Transporter, Protein family
