Transformation of high-RS mutant rice line ‘Jiangtangdao1’ with rice wild-type SBEIIb gene. A. Construct with the OsSBEIIb gene used for transformation of ‘Jiangtagndao1’. The clone contained the promoter region up to 2.3 kb upstream from the transcription start site and the transcribed region for the OsSBEIIb gene. B. Weight of individual mature T₁ kernels of the three transformed rice lines No-1, 19, and 20, the host mutant line ‘Jiangtangdao1’ and the wild-type cultivar ‘Huaqingdao’. The numbers above the bars indicate the average values (mg) ± SD (mg) (n = 15). C. Endosperm of ‘Jiangtangdao1’, ‘Huaqingdao’ and T₃ seeds of the transformed line No. 1–5, respectively.
