Embodiment

[0052] Hereinafter, the present invention will be specifically explained through examples. But of course, the present invention is not limited by this embodiment.

[0053] In order to obtain an example of the base sequence of a useful DNA tag, for Arabidopsis thaliana whose whole genome base sequence is disclosed, a sequence that does not exist in the genome is searched. As a database for Arabidopsis, the whole genome information provided by The Arabidopsis Information Resource (TAIR) (http: / / www.arabidopsis.org / ) is used. As a result of the search, as a sequence that does not exist in the Arabidopsis genome, the base sequence shown in SEQ ID NO:1 can be found. From this, it is known that an effective base sequence can be sought as a DNA tag.

[0054] This specification includes the content described in the specification and / or drawings of the Japanese Patent Application (Japanese Patent Application No. 2007-011739) on which the priority of this application is based. Moreover, all...

Abstract

A novel method of organism identification that can replace the conventional organism identification method by DNA requiring a large amount of labor. There has been developed a method of organism identification, namely, a method of identifying whether or not being a specified organism or a descendant thereof, characterized in that whether or not an identification object organism is a specified organism or a descendant thereof is judged by introducing in advance a DNA tag in cells of the specified organism or organism living parasitically or symbiotically therewith and finding whether the DNA tag is detected or not from the DNA extracted from the identification object organism or organism living parasitically or symbiotically therewith.

Description

Technical field [0001] The present invention relates to a method for identifying organisms using DNA tags, and more specifically, to a method for identifying individuals, species, habitats, etc. through the detection of specific base sequences. More specifically, it relates to a method of deliberately adding a specific base sequence to an inspection subject in advance, and then detecting the sequence to identify individuals, species, habitats, and the like. Since the base sequence of the DNA of an organism differs depending on the individual, species, habitat, etc., by using the identification method of the present invention, the individual, species, habitat, etc. of the organism can be discriminated. Furthermore, recently, the disguise of foods with attached seals and the mixing of genetic recombinants into foods have become social problems, and the identification method of the present invention can be applied to these disguise and mixing judgments. Background technique [0002]...
