Figure 1.

Morphological phenotypes of the s2-89 mutant (right) and its wild-type Nipponbare (left). (a) Whole plant phenotype at grain-filling stage. (b) Panicle morphology. (c) Grain morphology. The upper row: unhulled seeds; the lower row: hulled seeds. (d–h) Quantification of grain length, width, length-width ratio, thickness, and 1000-grain weight, Data are given as mean ± SE (n = 10). Double asterisks indicate significant differences between WT and s2-89 at P < 0.01 by Student’s t test. Each scale bar is indicated.
