The periphery of the endosperm of many plant species forms an epidermis-like layer called the aleurone. During germination, the aleurone performs an important digestive function, secreting hydrolases to break down the starch and proteins stored in the starchy endosperm cells.
What is the function of aleurone layer in maize?
The primary function of the viable aleurone layer during malting is to produce a wide range of hydrolytic enzymes that contribute to the degradation (modification) of the starchy endosperm. During malting, the germinated embryo produces and secretes gibberellic acid into the adjoining aleurone layer.
What is the aleurone layer in maize grain?
The aleurone layer is the outermost layer of the endosperm, followed by the inner starchy endosperm. This layer of cells is sometimes referred to as the peripheral endosperm. It lies between the pericarp and the hyaline layer of the endosperm.
