Distinct cell wall architectures in seed endosperms
in representatives of the Brassicaceae and Solanaceae.
This is shown by a comparison between the changes which take place in embryos germinated on their endosperms
and those which are excised and grown on sand moistened with a culture solution containing no carbohydrate The production of fresh cell wall material indicated by the increase in the insoluble fractions is as great in the excised embryos as in the germinating grains, both show a slight accumulation of maltose and in neither is there any marked accumulation of hexose.
Cell wall auto hydrolysis in isolated endosperms
of lettuce (Lactuca sativa L.
All tissue was freeze-dried and weighed again, except for the endosperms
of field-grown plants used in the L-[[sup.
Flour corns have starchy endosperms
(the central, fleshy part of each kernel), so they are the best type of corn for grinding into fine cornmeal, often called corn flour.
Two fatsoluble vitamins, provitamin A, or carotenoids, and vitamin E are present in the maize kernel with the former mainly present in the endosperms
and the latter in the germ.
Wasserman of Rutgers University, whose work focuses on the synthesis of amylose and amylopectin, and the molecular biology of the enzymes that catalyze chain elongation, insertion of branch points and spatial distribution of enzymes within the corn endosperms
For example, maize endosperms
that lack a paternal copy of one arm of chromosome 10 produce small kernels (Kermicle 1970; Lin 1984) and kernel size cannot be restored by adding extra maternal doses of that arm (Lin 1982).
In this way, the aim of this study was to evaluate the vitreousness of flint and dent endosperms
in grain corn hybrids and to study the effect of this feature on the agronomic behavior, nutritional value and ruminal digestibility of the grain harvested in silage maturity.
In the past decades, great effort has been made to recognize the effect of high temperature on grain quality, and it has been demonstrated that the deterioration of grain quality for rice exposed to high temperature is closely related to starch granule accumulation, starch components and its biosynthesis metabolism in filling endosperms
(Zakaria et al.
In summary, the results from this study can be useful for increasing the utilization of edible endosperms
of rice grains by decreasing embryo size in conventional cultivars.
A similar trend of the changes in Spm was also found in TN 351, except that endosperms
of shaded plants had a lower free Spm content than that of control plants.
