摘要:
In barley, the formation of D-hordein constituting gel protein is to be reduced. This reduction in the formation of D-hordein causes a reduction of gel protein because D-hordein fraction decreases in the gel protein; and in addition, it brings about the transformation (reduction) of proteins other than D-hordein which constitute the gel protein from the gel protein. Therefore, by introducing into barley D-hordein expression suppressing vector 1 capable of suppressing the D-hordein formation and transforming the barley therewith, it is possible to attain the reduction of gel protein based on the reduction in the D-hordein formation.

The present invention provides new gene expression regulatory DNA. This gene expression regulatory DNA comprises a promotor region derived from the barley D-hordein gene enabling the expression of a desired gene, and a regulatory region for regulating the expression of said gene based on said promoter region. This regulatory region consists at least of an activating region to activate the expression of said gene and a suppressing region to suppress the same.Use of this gene expression regulatory DNA enables controlling as desired the expression of gene within a plant cell such as barley.
摘要:
cDNA derived from the ARF gene that is actively expressed in barley seeds, roots and callus, but is highly suppressed or almost not expressed at all in leaves, was cloned. Next, the upstream region of the ARF gene was cloned, its promoter activity was verified, and a gene expression vector using the expression region of this gene was produced.

A method of selecting a barley variety comprising: a heat treatment step of heat-treating a crude enzyme solution extracted from a seed of a barley (e.g., at 57.5° C. for 30 minutes); an activity-determining step of determining the enzyme activity of β-amylase in the crude enzyme solution heat-treated; and a selection step of selecting the barley variety containing a β-amylase having a residual activity of from 85 to 90% as a result of the activity determination.
摘要:
A method for identifying barley with good brewing properties using the thermostability of the barley &bgr;-amylase as an indicator. The thermostability of the barley &bgr;-amylase significantly affects the degree of the apparent attenuation limit. A method for determining the enzyme activity of a extract solution from one barley seed, an indirect method by an isoelectric point, and an indirect identifying method by DNA polymorphisms of the region containing the &bgr;-amylase structural gene have been developed as a method for determining the type of thermostability for a barley &bgr;-amylase. The selection method is not affected by environmental or climatic conditions.
摘要:
The object of the present invention is to provide processed barley products which are rich in GABA even after milling of barley seeds, and a processing method therefore. The present invention provides a method for processing barley comprising a step in which barley seeds, whose GABA residue when processed to a pearling degree of 60% is 50% or greater compared to that of the unprocessed seeds, are milled without germination.

It is an object of the invention to provide a novel therapeutic agent that can reduce visceral fat accumulation to prevent or treat metabolic syndrome. In order to achieve this object, the invention provides a therapeutic agent for metabolic syndrome that comprises, as an active ingredient, dietary fiber aggregation in which water-soluble β-glucan has the highest content. Particularly effective as the water-soluble β-glucan is water-soluble β-glucan having a β-1,3 glycoside bond and β-1,4 glycoside bond in the same molecule.
