Question: what is aleurone layer in maize grain?
Answer: Aleurone. The aleurone is a single layer of cells and it is considered the outer coating of the endosperm (Figs. 6.1, 6.5, and 6.6). This layer covers the entire starchy endosperm and the germ, and it is interrupted only at the hilar layer at the kernel tip and is thinnest over the germ.
