発明の名称 (英語) QSD1 GENE GOVERNING SEED DORMANCY OF PLANTS, AND USE THEREOF
発明の概要(英語) Qsd1 gene which governs the seed dormancy of barley can be identified successively by a positional cloning technique. A single nucleotide polymorphism (SNP) that correlates with the above-mentioned seed dormancy and is located in the gene can also be specified successively, and it can be found out successively that an individual in which a weakly seed-dormant gene is dominant and the gene is heterogeneous has a weakly seed-dormant genotype. Further, based on the sequence information on Qsd1 gene of barley, the corresponding Qsd1 gene of wheat can also be identified successively. Then, it is found that the determination of the degree of seed dormancy of a plant and the production of a plant having altered seed dormancy can be achieved with high efficiency using the identified gene.
従来技術、競合技術の概要(英語) BACKGROUND ART
Seed dormancy-one adaptive traits of wild plants and environment, in particular the object of this middle and near east wild plants such as in a dry area, not to germinate in the summer the fault condition is important to elapses. On the other hand, in the cultivated plant, to shorten the period up to harvesting agricultural seeded on the selected from strong, usually is of shallow sleep, sleep is excessively small ear harvested crop in the early phase of rainfall by fatal results in a reduction of quality. Further, brewer's barley germination such deflection is made too deep sleep is not, resulting in the manufacture malt. In this way, from the viewpoint of industrial crop seeds and the evolution of the diapauze of essential importance. In addition, the genome homology barley seed dormancy gene and the common genes is also present in the wheat has been identified (non-patent document 1), to identify if the sleep of the barley gene, serious damage after germination of the wheat ears than the controllability of the diapauze expected to also be applied.
Cultivated barley 'beneath a double' and wild barley 'H602' separated by the heterozygous and wild barley hybrid progeny seed dormancy QTL-derived from 4 have been identified which have heretofore been locus (non-patent document 2), 1 of which one Qsd1in. These QTL is, the high density marker map EST chain (non-patent document 3) and the tandem seat. In addition, known markers may be linked to the Qsd1 (patent document 1).
However, because of its hard, still Qsd1critical to the success of the identification of genes not yet.
