2002) GA-induced programmed cell death was delayed in aleurone layers in the presence of NO in barley plants that associated with a loss of activity of catalase and superoxide dismutase (SOD).
Nitric oxide acts as an antioxidant and delays programmed cell death in barley aleurone layers.
Milling or processing strips the aleurone layer, and the grains contain fewer essential micronutrients.
Vein of gold[R] consists oldie most nutritious fraction of the wheat grain: the aleurone layer of the wheat kernel.
As the wheat aleurone is light in colour and only used at low dosages, end products do not take on a wholegrain appearance.
Since the most of phytate in plant are located in protein body at aleurone layer or near cell wall by making protein-phytate complex, initial hydrolysis of phytate by phytase may facilitate the release of protein and their amino acids.
These results imply that xylanase could increase the access of phytase to phytate in the aleurone layer of wheat, where phytate is concentrated.
Friabilins were only found in the endosperm of the grain, and not in the aleurone layer.
The aleurone layer was less ordered in frost damaged than in normal grains, and was not always readily distinguished from the starchy endosperm.
When milling, the extraction rate influences the quality of the flour or the bran (for example, nutrient digestibility is higher in bran fractions rich in aleurone than in fractions rich in outer pericarp).
It is derived from the outer layer of Caryopses during milling and includes pericap, seed coat, aleurone layer, germ and part of the subcutaneous layer of starchy endosperm.
