Fig. 3

a A longitudinal section of the mature W64A kernel. The section was observed under the natural light. Bar = 1 mm. b Scanning electron microscopy of the longitudinal section of the mature W64A kernel. The dotted lines mark the areas of the vitreous endosperm, starchy endosperm, and embryo. The blue circle shows the location of the enlarged image on the right panel. VE vitreous endosperm, SE starchy endosperm, EM embryo, SG starch granule. Bars = 200 μm. The experiment was independently repeated three times. c Spatial expression patterns of starch synthesis-related genes in maize kernel. d Spatial expression patterns of zein genes in maize kernel. e Sudan IV dyeing of the longitudinal section of the mature W64A kernel. The red staining mainly occurred in SCU. The section was observed under natural light. Bar = 1 mm. f Spatial expression patterns of oil synthesis-related genes in maize kernel.
