Fig. 6From: Unique Glutelin Expression Patterns and Seed Endosperm Structure Facilitate Glutelin Accumulation in Polyploid Rice SeedVariations in endosperm structural characterization in rice seeds with various ploidy levels. Semi-thin sections of the dehusked immature seeds of 9311 and A3 (harvested in 2018) at 17 DAF stained with methylene blue, (A–D) PAS, and CBB (E–H). Scale bar: 100 μm (A–D) and 200 μm (E–H). Seed coat, aleurone layer, and starchy endosperm are represented by black horizontal lines. Blue granules are indicated by black arrowheads, which represent plant proteins. Red granules are indicated by black triangles, which represent plant polysaccharidesBack to article page
