Model of dominant and matching control modes in Cymbidium mosaic potexvirus movement between cells. The M1 CP plays a dominant role in controlling the trafficking of the infection between cells. However, besides the CP-mediated dominant control, another control mode that requires correct matching of TGBp1, TGBp3, CP and 5' RNA also allowed the movement of CymMV between cells. The red and blue lines indicate the functional combination of movement accessory components in dominant and matching control modes, respectively. The gray lines indicated the incorrect matching of movement accessory components. The M1 and M2 RNAs, TGBp1s, TGBp2s, TGBp3s and RNA-dependent RNA polymerase (RdRp) are indicated.
