| Description: | The rice mitochondrial iron transporter is essential for plant growth In plants, iron (Fe) is essential for mitochondrial electron transport, heme, and Fe Sulphur (Fe S) cluster synthesis; however, plant mitochondrial Fe transporters have not been identified. Here we show, identify and characterize the rice mitochondrial Fe transporter (MIT). Based on a transfer DNA library screen, we identified a rice line showing symptoms of Fe deficiency while accumulating high shoot levels of Fe. Homozygous knockout of MIT in this line resulted in a lethal phenotype. MIT localized to the mitochondria and complemented the growth of yeast defective in mitochondrial Fe transport. The growth of MIT knockdown (mit 2) plants was also significantly impaired despite abundant Fe accumulation. Further, the decrease in the activity of the mitochondrial and cytosolic Fe S enzyme, aconitase, indicated that Fe S cluster synthesis is affected in mit 2 plants. These results indicate that MIT is a mitochondrial |
