Outline Activities

1. Research on the Exploration and Functional Analysis of Beneficial Genes in Insects
Focusing on the world's largest collection of silkworm mutants preserved at Kyushu University, my research involves breeding experiments, next-generation sequencing analysis, genome editing, and physiological/biochemical experiments. Through the analysis of the causative genes of mutants, I aim to explore and analyze the functions of beneficial genes in insects.
2. Genetic Basis of Silkworm Domestication
The domestication of silkworms (Bombyx mandarina) is believed to have resulted from the long-term breeding of wild silkmoths (B. mandarina) by humans. The current silkworms, which cannot survive in the wild, represent the ultimate domestication by humans. I aim to elucidate how the genome and genes change during the differentiation from B. mandarina to B. mori by employing consomic strains.
3. Research on Silkworm Cryopreservation Techniques
Silkworms are insects that undergo dormancy in the embryo stage. Since dormant silkworm eggs can only be stably preserved for one year, it is necessary to rear and obtain eggs every year from each strain. To streamline the efforts required for breeding and prevent the loss of valuable genetic resources due to diseases or accidents, research is being conducted on the cryopreservation technique of reproductive organs.

Message

I conduct a wide range of studies, including crossing experiments, molecular genetics experiments, genome editing, transgenic experiments, cryopreservation of reproductive organs, and data analysis using computers. If you are interested in unraveling the genetic mechanisms underlying the diverse traits in insects, using silkworms as a model, please feel free to contact me.
