| Outline of Final Research Achievements |
In recent years, it has become clear that various plants in the natural world have a base sequence homologous to the viral genome on the genome and that the virus is persistently infected. In this study, we elucidated the role and specific molecular basis of viruses that infect plants without showing clear symptoms in their vital activities. As a result, it was shown that the cytosine methylation/demethylation level of the promoter region of the host gene contributes to resistance to environmental stress through fluctuations due to persistent infection of the virus. Furthermore, it was clarified that the expression of the viral genome existing in the host genome changes the flower pattern. These findings provide new insights into the role of viruses in plant life activities.
