| Research Abstract |
In the present study, we identified two novel transporters for Zn in rice (Oryza sativa. L). OsMTP7 expresses around stele showed Zn transport ability in Saccharomyces cerevisiae. Knockout of OsMTP8 resulted in decreased and increased accumulation of Zn in the shoots and roots, respectively. Signal of GFP fused with OsMTP8 was detected in plasma membrane. Further, accumulation of OsMTP8 is suppressed by elevated level of Zn. These results suggest that OsMTP8 is involved in Zn translocation. The findings in this study will be beneficial for Zn fortification in rice.
