| Outline of Final Research Achievements |
Sex chromosomes of the silkworm, Bombyx mori, are designated as ZW (XY) for females and ZZ (XX) for males. The female mode of development is determined by the presence of a single W chromosome. No genes for morphological traits have been mapped to the W chromosome. Many long terminal repeat (LTR) and non-LTR retrotransposons, retroposons, DNA transposons, and their derivatives, had accumulated as strata on the W chromsosome. It is notable that some of these transposable elements contained the Bombyx short interspersed element (Bm1) sequences in the elements.
A mutant strain (op mutant) of the silkworm, Bombyx mori, was proposed as a model for Parkinson's disease. A previously reported study movie documenting occasional unique actions of op/op larvae was considered; it revealed that these actions were simply reactions to the touch of other larvae. Moreover, xanthine oxidase injection did not rescue the phenotype of op mutant larvae.
