Microscopic analysis of starch granules in WT (L<i>er</i>), <i>pgi1–2</i> and <i>pgi1–3</i> source leaves.

<p>(A-C) Light microscopy of toluidine stained leaf sections (Bar = 50 μm). (D-F) Magnification of mesophyll sections indicated in A-C (Bar = 10 μm). (G-I) TEM of WT, <i>pgi1–2</i> and <i>pgi1–3</i> leaves. Bar = 2 μm. (J-L) CFM of leaves of GBSS-GFP expressing WT, <i>pgi1–2</i> and <i>pgi1–3</i> leaves. Bar = 5 μm. Plants were cultured on soil under LD conditions and source leaves harvested from 30 DAG plants after 12 h of illumination. In D-F, arrows indicate the position of starch granules. St: starch.
