Figure 4

(a) Correlation between grain width (GW) and trigonelline content in 489 rice varieties. (b) Comparison of spikelet hull. Left: spikelet (scale bar, 3 mm). Middle: cross-section of spikelet hull (scale bar, 500 μm). Right: comparison of grain width. (c) Magnified view of spikelet hull cross-section from the box in b. Scale bar, 50 μm. Comparison of cell number, mean cell length and width in the outer parenchymal cell layers of spikelet hulls of WT, over-expression (OX) and RNA interference lines, respectively. (d) Transcript levels of genes associated with cell cycle regulation. (e) Transcript levels of genes involved in mitosis. The r value is based on the Pearson correlation coefficient. The P value is calculated using the Student’s t tests. WT: the transgenic background variety ZH11. Data are shown as the means±s.e.m., n=3.
