Fig. 3From: Overexpression of the Barley Nicotianamine Synthase Gene HvNAS1 Increases Iron and Zinc Concentrations in Rice GrainsEndogenous NA and DMA concentrations in T1 plants determined via high-performance liquid chromatography (HPLC). a NA concentrations. b DMA concentrations. NA and DMA were extracted from 44-day-old plants grown hydroponically under Fe-sufficient conditions. The data represent the mean ± standard error of three measurements for each sample. White bars, shoot concentration; gray bars, root concentration; NT non-transgenic line; 35S, 35S-HvNAS1 transgenic line; AN1, AN2, and AN3, OsActin1-HvNAS1 transgenic lines. Distinct letters above the bars indicate significant differences (p < 0.05).Back to article page
