HDR3 regulates grain size presumably through its positive role in the regulation of cell number in spikelet hulls. A, C, Mature grain and scanning electron microscopic analyses of the outer surfaces of the spikelet hulls of overexpressing rice lines HDR3-OE-1 and the gene knockout lines hdr3-1, and the corresponding control (Nipponbare). White bar = 200 μm; yellow bar = 5 mm. B, D, Comparisons of cell length, and the total of cell number, of the spikelet hulls along the grain length orientation of the transgenic lines HDR3-OE-1 and hdr3-1, respectively, with the corresponding control (Nipponbare). Student’s t test was used to generate the P-values.
