Supplementary Figure 11: The effect of GW7 transcript abundance on scanning electron microscopy images of the transverse sections of starch granules.

(a) NIL-gw7HJX74 plants. (b) NIL-GW7TFA endosperm comprised largely sharp-edged, compactly arranged polygonal starch granules when compared to NIL-gw7HJX74 ones. (c) Transgenic NIL-gw7HJX74 plants overexpressing the TFA GW7 cDNA driven by its native promoter.
