Outline Activities
Research
The domesticated silkworm, Bombyx mori expresses very diverse morphological and ecological traits. This insect also shows specific biological phenomena including diapause, metamorphosis, behavior and so on. We, laboratory of Silkworm Genetics Resources, have about 500 silkworm strains that have been collected from all part of the world, and function as the most important center for silkworm genetic resources in the world. All mutants offer to researchers for laboratory tools or education materials. To preserve these heritages of mankind is our basic work. For maintenance of them with safety, it is absolutely necessary to perform systematic genetic mapping of mutant traits. At present the phenotype linkage maps of this insect provide more than 230 gene loci distributed among 27 linkage groups (n=28). We also focus on the integration between the molecular linkage maps and the phenotype linkage maps of this insect. Development of the integration among maps promotes analyzing specific biological phenomena observed in this insect and other lepidopteran insect.
Education
Our goal for education is promotion of the highly motivated students who can find their own life and research subjects. In course, we are teaching adequate methods for experiment (genetics, biochemistry, histology) and offering research subjects. Subjects are listed as follows:
1. Linkage analysis of silkworm
2. Analysis of gene expression
3. Mutagenesis in the silkworm
4. Maintenance of the mutant stocks
5. Construction and integration of a genetic linkage map of silkworm genome
6. Cytogenetical studies of silkworm
7. Studies on origin and differentiation of silkworm
Social activities
We are performing the open class for the schoolchild and teachers in every summer. The purpose of a seminar is for raising the child who gets interested in a science. They can experience rearing of silkworm, reeling of the silk thread from cocoon and textile of silk. Kindly cooperator supports this seminar.

Current and Past Project
- National bio-resource project
Convenient laboratory organisms are basically required to make the No.1 science and technology of the world. The Ministry of Education, Culture, Sports, Science and Technology of Japan started the national bio-resource project in 2002. Silkworm was chosen as one animal of about 20 kinds of the object species. Our laboratory was selected as a core organization for a project. The main purposes of this project are collection, preservation, and offer of genetic resource of silkworm with high quality.
