| Abstract: |
| Zinc and iron are mineral elements necessary for plant growth, but excessive absorption is toxic for plant.
Plants use members of Zinc and Iron Transporter (ZIP) family to absorb and transport zinc and iron. So this family proteins
play important role in the control of zinc and iron balance in plant. In this study, the characteristics, structures and
molecular phylogeny of plant zinc and iron transporters were predicted by bioinformatical methods. The results showed that
this family proteins were composed of 226-459 amino acids. They were transmembrane proteins, most of which were
located in plasma membrane, chloroplast and vacuole. Their phylogeny was complicated which was not in accordance with
the phylogeny of species, which suggested the this family proteins diverged earlier. Th results can provide the theory
foundation for further research on cloning of the family genes and studying about their structures and functions. |
