Rice seed samples and schematic diagram of the experimental approaches used in this study. A, Appearance of dehulled mature seeds in various transgenic rice lines and their wild type (WT). GR-14 and 35S-15 transgenic lines were generated by transformation of the GR and 35S constructs into the wild type, respectively. The HFL1 pyramiding transgenic line was produced by crossing GR-14 and 35S-15 lines (35S-15/GR-14) and contained the above two transgenic constructs. HFL1-N and HFL1-D were mature seeds with normal or dark-brown appearance, respectively, from the same set of HFL1 transgenic lines. Bar = 10 mm.
