Suppressed expression of miR159 reduces the size of spikelet hulls. a Phenotype of mature spikelet in wild type and STTM159 transgenic plants. Dashed line indicates the position of the cross sections. b Cross-sections of the spikelet hulls of wild type and STTM159 plants. c Magnified views of the cross-section of the spikelet hulls of wild type and STTM159 plants. Scale bars, 1 mm. d Statistical data of the cell numbers in the outer parenchyma layer of the spikelet hulls of WT and STTM159 transgenic plants (n = 15). Values are the means ± S.D., **P < 0.01
