3. II. Graduate School Experience & Thesis
- Affiliation: Lab of Insect Molecular Biology and Toxicology
- Thesis: Development of Film-assisted Honeybee Egg Collection System (FECS) and
Its Application to Honeybee Genome Editing.
- Thesis Summary: Improve honeybee genome editing protocol and prove
concept of pesticide resistant honeybee
PART1: Film-assisted Honeybee Egg Collection System (FECS)
Developed massive honeybee egg(embryo) collection system exploiting 3D
printing technique and silicone coating. Expected to be utilized in various
honeybee research such as toxicity evaluation and developmental biology
aside from genome editing
* Published in Apidologie (SCI journal) as the first author.

4. II. Graduate School Experience
PART II: Knock Out of Honeybee nAChR alpha6 gene
Edited honeybee genome to prove the concept of pesticide resistant honeybee
which can be free from the fear of residual pesticides (in agricultural
environment) and parasitic mites resistant to conventional miticides. nAChR
alpha 6 gene (which express the target protein of the pesticide Spinosad) was
successfully knocked-out (confirmed knock-out from F1)
* nAChR is Cation Channel acting on neurons and consist of five subunits. Knock-Out or G275E point mutation
on alpha6 subunit gene is a well-known inducer of Spinosad resistance in Insects.
