摘要:
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:
A transformed plant of Gramineae is prepared by culturing an anther of Gramineae in a callus induction medium and, at a stage immediately before the microspore begins to cause division or during the initial division, transducing a genetic substance into the microspore cell through a pore formed by a laser pulse thereby to express genetic information of the genetic substance.According to the present invention, it is unnecessary to prepare protoplast and therefore, time and operations for transformation can be greatly reduced. Since haploid cells are transformed, the character transduced is conveyed without separating at a later generation. In addition, difficulties in experiments between species and strains are minimized so that it is easy to apply the present invention to practical species. According to the present invention, large pores can be formed as compared to the electroporation method so that DNA or substances having a large molecular weight can be introduced.
摘要:
A character object CH1 is first projected onto a screen plane, and a masked area is rendered as a circular area that is centered about the position of the character object CH1 projected onto the screen plane. The obtained image data is stored in a main memory as mask data, and is used when rendering each object in a virtual game space. A transparency flag is set in advance for each of field objects OB1 to OB3. The field object OB1 whose transparency flag is “1” is rendered by using the mask data, whereas the character object CH1 and the field objects OB2 and OB3 whose transparency flag is “0” are rendered normally. Thus, it is possible to provide a video game device capable of displaying a particular object such as the player character so that it can always be seen, with minimum detraction from the atmosphere of the game field.
摘要:
A selection method for barley lipoxygenase-1 deficient barley, comprising a step of distinguishing the barley lipoxygenase-1 deficient barley by whether or not the guanine at the splicing donor site of the 5th intron of the barley lipoxygenase-1 gene is mutated to a different base; and a method for production of malt alcoholic beverages using a material for malt alcoholic beverages derived from barley obtained by the selection method.
