Gene Details:

• MSU gene ID: LOC_Os07g12890
• RAPdb gene ID: Os07g0232800
• Gene Symbol: OsZIP8
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The OsZIP8-GFP fusion proteins were localized to the plasma membrane, suggesting that OsZIP8 is a plasma membrane zinc transporter in rice.
• Altogether, these results demonstrate that OsZIP8 is a zinc transporter that functions in Zn uptake and distribution.
• Zinc deficiency-inducible OsZIP8 encodes a plasma membrane-localized zinc transporter in rice.
• It suggested that the OsZIP7a and OsZIP8 might encode an iron and a zinc transporter protein in rice respectively.
• By semi-quantitative RT-PCR approach, it was found that the expression of OsZIP7a was significantly induced in rice roots by iron-deficiency, while that of OsZIP8 induced in both rice roots and shoots by zinc-deficiency.
• To investigate its transport in rice, we characterized OsZIP8, a rice ZIP (Zrt, Irt-like Protein) gene that is strongly up-regulated in shoots and roots under Zn deficiency.
• OsZIP8 could complement the growth defect of Zn-uptake yeast mutant.
• When expressed in yeast cells, OsZIP7a and OsZIP8 could complement an iron-uptake-deficient yeast mutant and a zinc-uptake-deficient yeast mutant respectively.
