| Research Abstract |
The gene responsible for ov (mottled translucent of Var) and ovp (ov of pinhead) was identified by positional cloning based on the genome information, and was revealed to be Bmdysb, encoding the Dysbindin, a subunit of BLOC-1, a protein complex required for formation of lysosome-related organelles (LROs). The transcription of Bmdysb was drastically reduced in ov and ovp. Other larval translucent mutants, obt and otm were also investigated. These mutants were caused by the genes encoding different subunits of BLOC-1, respectively. Therefore, it is concluded that the subunits of BLOC-1 play crucial roles in formation of urate granules in the cells of larval epidermis of the silkworm.
