GWD1 is a positive regulator of seed germination in rice. Germination rates of the three pOsl2::GWD1 transgenic rice lines (a) and the two gwd1 mutants (b) and their WT controls. Representative photos of the starch board test of s pOsl2::GWD1 transgenic line (c) and a gwd1 mutant (d) and the respective control lines 9983 and ZH11. Diameters of the colourless halos produced by the grain samples from the pOsl2::GWD1 transgenic line (e) and the gwd1‐1 mutant (f). α‐amylase activity in the grains of the pOsl2::GWD1 transgenic line (g) and the gwd1‐1 mutant (h). Each experiment was repeated at least three times. Error bars represent the SDs. **P < 0.01 (Student’s t‐test)
