Blue value (BV) and maximum absorption wavelength (λmax) of ZmGRAS20. a Absorbance spectra of isolated amylose-iodine complexes of ZmGRAS20-overexpression plants. BV at 600 nm and λmax represent the ability to combine with iodine. b Absorbance spectra of isolated amylopectin-iodine complexes of ZmGRAS20-overexpression plants. BV at 680 nm and λmax represent the ability to combine with iodine. WT, rice japonica cv. Zhonghua 11 as a wide type; CK, rice contains pCAMBIA1301a as a control check; L1–L4, four independent transgenic lines of ZmGRAS20. Data are presented as mean ± SD of three replicates. **Significant differences between WT and transgenic plants at P < 0.01, respectively
