expression in rice. Overexpression of the nicotianamine synthase gene enhances nicotianamine level, enhances the Fe and Zn concentrations and confers tolerance to Fe deficiency in calcareous soil
expression in soybean, sweet potato, tobacco or rice. Overexpression of the nicotianamine synthase gene enhances nicotianamine level, enhances the Fe and Zn concentrations and confers tolerance to Fe deficiency in calcareous soil
expression of a barley HvNAS1 nicotinamine synthase gene promoter-gus fusion gene in transgenic tobacco is induced by Fe-deficiency in root
-
sweet potato plants (Ipomoea batatas) expressing the nicotianamine synthase 1 (HvNAS1) gene under the control of CaMV 35S promoter are produced by Agrobacterium-mediated transformation
transgenic Arabidopsis and tobacco plants constitutively overexpress the enzyme from Hordeum vulgare. Nicotianamine synthase overexpression results in increased biosynthesis of nicotianamine in transgenic plants, which conferrs enhanced tolerance of high levels of metals, particularly nickel, to plants. Promoter activities of four nicotianamine synthase genes in Arabidopsis are all increased in response to excess nickel, suggesting that nicotianamine plays an important role in the detoxification of nickel in plants. Transgenic tobacco plants with a high level of nicotianamine grew well in a nickel-enriched serpentine soil without developing any symptoms of nickel toxicity
