| Research Abstract |
In the researches of plant viruses, the molecular machinery of the cell-to-cell movement process is poorly understood. In this study, we focused plant non-cell autonomous proteins (NCAPs) and analyzed the cross-talks between the cell-to cell movement of NCAPs and tobacco mosaic virus (TMV). We showed that a tobacco NTH2O1, a KN1 family protein, and a tobacco NtMPIP1, a heat-shock protein, cooperatively promote the cell-to-cell movement of TMV via the interaction with TMV MP. These results elucidated a part of the cell-to-cell movement mechanism and established the basis of anti-viral strategy to inhibit the cell-to-cell movement.
