| Outline of Final Research Achievements |
The Bombyx mori macula-like virus (BmMLV) is a member of the genus Maculavirus, family Tymoviridae, and contains a positive-sense single-stranded RNA genome. Previously, we reported that almost all B. mori-derived cell lines have already been contaminated with BmMLV via an unknown infection route. To understand the mechanism of BmMLV propagation, we identified a novel subgenomic RNA of BmMLV. Also, we determined several viral inactivation methods by using the physical conditions. Furthermore, we revealed that BmMLV did not replicate in nine mammalian-derived cell lines. RNA-seq analysis was also performed to clarify the mechanism of BmMLV persistent infection.
