| Research Abstract |
In order to measure the level of antigen-antibody reaction against wheat storage protein related to wheat allergy, three kinds of peptide polyclonal antibody were produced. Using the antibody, about 170 lines of wheat were screened by the western-blot analysis. Furthermore, to understand genome structure and the expression of allergen α/β-gliadin multigenes, genome analysis was conducted. Duplication of genome segments containing of α/β-gliadin genes brought about through unequal crossing-over or saltatory replication, and α/β-gliadin genes for their own were duplicated without any recombination events. They have similar cis-elements and promoter structures, the mechanisms underlying their distinct gene expression and possible applications were suggested.
