| Outline of Final Research Achievements |
Segmented genome of influenza A virus is thought to form a higher order complex by selective assembly of 8 different viral ribonucleoprotein complex (vRNP) before packaging. In this study, focusing on the mechanisms of vRNP trafficking and assembly in the infected cells, an experimental system for measuring the proximity of vRNP segments was established. By using this system, it was revealed that the selective segment assembly occurs most likely in the cytoplasm after the nuclear export of progeny vRNP. For this assembly process, the microtubule-dependent apical transport is not required.
