Molecular identification of OsGRAS23-overexpressing transgenic lines. A Schematic diagram of overexpression construct. LB, left border; HPT, hygromycin phosphotransferase; PCaMV35S, cauliflower mosaic virus 35S promoter; TNOS, nopaline synthase gene terminator; and RB, right border. B Relative expression levels of OsGRAS23 in transgenic rice lines. WT: wild type, OE1-OE58: transgenic lines. The gene expression level was analyzed by quantitative real-time PCR. The data represent the mean ± SE (n = 3). C Phenotypes of transgenic rice plants and WT plants grown in PVC pipes
