| Outline of Final Research Achievements |
Virus-like particle (VLP) is a self-assembled capsid protein of virus and the best candidate of edible vaccine, because some VLP is resistant to digestion and can be targeted to the immune system of intestine. We tried to make transplastomic plants of carrot (Daucus carota L. cv. Kurodagosun) and tobacco (Nicotiana tabacum cv. SR-1) expressing capsid protein of Human Hepatitis E Virus (HEV) fused with the M2 universal epitope of Infuenza type A virus that will be an ideal edible vaccine. We could obtain candidate of transplastomic carrot embryogenic callus and homoplasmic tobacco plants. Some tobacco plant contains the vaccine protein that is enough concentration for immunogenicity feeding test of mice.
