The Role of Microtubule Association in Plasmodesmal Targeting of Potato mop-top virus Movement Protein TGBp1
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...
متن کاملReplication-independent long-distance trafficking by viral RNAs in Nicotiana benthamiana.
Viruses with separately encapsidated genomes could have their genomes introduced into different leaves of a plant, thus necessitating long-distance trafficking of the viral RNAs for successful infection. To examine this possibility, individual or combinations of genome segments from the tripartite Brome mosaic virus (BMV) were transiently expressed in leaves of Nicotiana benthamiana plants usin...
متن کاملCell-to-Cell Movement and Protein Interactions of Potato mop top virus
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...
متن کاملEvolutionary features of 8K (KDa) silencing suppressor protein of Potato mop-top virus
The cysteine-rich 8K protein of Potato mop-top virus (PMTV) suppresses host RNA silencing. In this study, evolutionary analysisof 8K sequences of PMTV isolates was studied on the basis of nucleotide and amino acid sequences. Twenty-one positively selected sites were identified in 8K codingregions. Recombination events were found in the 8K of PMTV isolates with a rate of 1.8. Totally 30 haplotyp...
متن کاملImportin-a-Mediated Nucleolar Localization of Potato Mop-Top Virus TRIPLE GENE BLOCK1 (TGB1) Protein Facilitates Virus Systemic Movement, Whereas TGB1 Self-Interaction Is Required for Cell-to-Cell Movement in Nicotiana benthamiana
Recently, it has become evident that nucleolar passage of movement proteins occurs commonly in a number of plant RNA viruses that replicate in the cytoplasm. Systemic movement of Potato mop-top virus (PMTV) involves two viral transport forms represented by a complex of viral RNA and TRIPLE GENE BLOCK1 (TGB1) movement protein and by polar virions that contain the minor coat protein and TGB1 atta...
