27 28 Functions of viral proteins can be regulated through phosphorylation by serine/threonine kinases 29 in plants but little is known about involvement of tyrosine kinases in plant virus infection. In this 30 study, TGBp3, one of the three movement proteins encoded by a triple gene block (TGB) of 31 Potato mop-top virus (PMTV), was detected for the first time in PMTV-infected plants and 32 fo...

Cell-to-cell movement of Potato mop-top virus (PMTV) is mediated by three virus-encoded 'triple gene block' (TGB) proteins termed TGBp1, TGBp2 and TGBp3. TGBp1 binds virus RNAs to form viral ribonucleoprotein complexes (vRNPs), the transport form of viral genome. TGBp2 and TGBp3 are necessary for intracellular delivery of TGBp1-containing vRNPs to plasmodesmata. To analyze subcellular localizat...

The potato mop-top virus (PMTV) triple gene block 2 (TGB2) movement proteins fused to monomeric red fluorescent protein (mRFP-TGB2) was expressed under the control of the PMTV subgenomic promoter from a PMTV vector. The subcellular localizations and interactions of mRFP-TGB2 were investigated using confocal imaging [confocal laser-scanning microscope, (CLSM)] and biochemical analysis. The resul...
