From: Barley callus: a model system for bioengineering of starch in cereals
Scanning electron microscopy (SEM) of starch granules. Scanning electron microscopy (SEM) pictures of (a,c) Ubi:GFP control callus and (b,d) barley endosperm starch granules. A magnification of starch granules with the characteristic doughnut-shape is indicated in the lower right corner of (c). Scale bars represent 50 μm in (c,d) and 5 μm in (a,b).
