Morphology of WT (S482) and SM482gs mutant grains. a The grain phenotype of WT and SM482gs mutant in four developmental stages. Bar = 1 mm. b Average grain length of WT and SM482gs mutant in four developmental stages (n = 30 each). c Average grain width of WT and SM482gs mutant in four developmental stages (n = 30 each). d Mature grains of WT and SM482gs mutant. Bar = 1 mm. e Average grain length and width of the mature grains (n = 30 each). f 1000-grain weight of the mature grains (n = 100). Data (b, c, e, f) are expressed as means ± SDs. *p ≤ 0.05 (Student’s t-test)
