Importin-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...
متن کاملAltMV TGB1 Nucleolar Localization Requires Homologous Interaction and Correlates with Cell Wall Localization Associated with Cell-to-Cell Movement
The Potexvirus Alternanthera mosaic virus (AltMV) has multifunctional triple gene block (TGB) proteins, among which our studies have focused on the properties of the TGB1 protein. The TGB1 of AltMV has functions including RNA binding, RNA silencing suppression, and cell-to-cell movement, and is known to form homologous interactions. The helicase domains of AltMV TGB1 were separately mutated to ...
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 کاملInteractions of the TGB1 protein during cell-to-cell movement of Barley stripe mosaic virus.
We have recently used a green fluorescent protein (GFP) fusion to the gammab protein of Barley stripe mosaic virus (BSMV) to monitor cell-to-cell and systemic virus movement. The gammab protein is involved in expression of the triple gene block (TGB) proteins encoded by RNAbeta but is not essential for cell-to-cell movement. The GFP fusion appears not to compromise replication or movement subst...
متن کاملLocalization of Barley yellow dwarf virus Movement Protein Modulating Programmed Cell Death in Nicotiana benthamiana
Barley yellow dwarf virus (BYDV) belongs to Luteovirus and is limited only at phloem related tissues. An open reading frame (ORF) 4 of BYDV codes for the movement protein (MP) of BYDV gating plasmodesmata (PD) to facilitate virus movement. Like other Luteoviruses, ORF 4 of BYDV is embedded in the ORF3 but expressed from the different reading frame in leaky scanning manner. Although MP is a very...
