Phenotypic comparison between WT and the gwt1 mutant. a Segregating ear of heterozygote (+/-) in B73 background. The red arrowheads indicate gwt1 kernels. Scale bar, 1 cm. b-e Comparison of wild-type (WT) and gwt1 kernels from the same ear. b-c is for kernels of 10 DAP and d-e is for mature kernels. Scale bar, 1 cm for d and 0.5 cm for b, c and e. f Germination appearance between WT and gwt1. Scale bar, 1 cm. g Comparison of plant height and ear height between WT (n = 17) and gwt1 (n = 11)
