"But if we can get the aleurone
to stay with the endosperm, then that would increase our quantities of flour - and it is also highly nutritious."
The rice grain has three parts -- the aleurone
layer, the endosperm and the embryo.
Shen, "A rice WRKY gene encodes a transcriptional repressor of the gibberellin signaling pathway in aleurone
cells," Plant Physiology, vol.
Common mechanisms regulating expression of rice aleurone
genes that contribute to the primary response for gibberellin.
The diminished capacity in production of amylase in the aleurone
from seeds apparently is due to a decrease in expression of the [alpha]-amylase genes.
In a landmark article (cited by over 175 other research papers), Ernst Graf and John Eaton state that it mainly occurs as a mixed Ca-Mg-K salt in discrete areas such as the aleurone
layer of wheat and rice.
For example, the R gene in maize controls the color of pigment gains in the aleurone
(outer layer of endosperm) of the kernel.
It is a powdery fine, fluffy material that consists seeds or kernels, in addition to particles of pericarp, seed coat, aleurone
, germ and fine starchy endosperm and rich in B-vitamins and its nutrient density and profiles of amino acids, including 74% of unsaturated fatty acids, are superior to cereal grains .
For seeds, we soaked seeds in 5% sodium hydroxide solution for 24 h, then dissected out the aleurone
layer from the seed and stained this layer with the same aniline blue plus lactic acid stain used for staining tillers (Clark et al., 1983).
Within sections on soluble fibers, resistant starch, conventional fibers, and new development, the studies examine such ingredients as inulin, pectin, oat fiber from oat hulls, sugar beet fiber, psyllium, and the novel wheat ingredient aleurone
Ferulic acid is mainly present within the cell walls of the aleurone
layer bound to arabinoxylans and other polysaccharides or proteins.
Effect of wheat pericarp ball-milling on fragmentation and marker extractability of the aleurone
