Total nitrogen content in different plant tissues of transgenic and wild type plants. When grown in a full nutrient containing medium, transgenic OsGRX6 plants had significantly higher total nitrogen content in the leaves, shoots, and seeds than that of wild type plants. First two groups represent the total nitrogen in the shoots of wild type and transgenic plants collected either at 4 weeks after planting or at harvest. The last group presents the nitrogen content in de-husked seeds. Data are means ±SD of four replicates. Asterisks indicate significant differences at P ≤ 0.05 level for each group.
