The 5' untranslated region of alfalfa mosaic virus RNA 1 is involved in negative-strand RNA synthesis.

چکیده
The three genomic RNAs of alfalfa mosaic virus each contain a unique 5' untranslated region (5' UTR). Replacement of the 5' UTR of RNA 1 by that of RNA 2 or 3 yielded infectious replicons. The sequence of a putative 5' stem-loop structure in RNA 1 was found to be required for negative-strand RNA synthesis. A similar putative 5' stem-loop structure is present in RNA 2 but not in RNA 3.

The minus-strand promoter of Alfalfa mosaic virus (AMV), a tripartite plant virus belonging to the family Bromoviridae, is located within the 3'-terminal 145 nucleotides (nt), which can adopt a tRNA-like structure (TLS). This contrasts with the subgenomic promoter for RNA4 synthesis, which requires approximately 40 nt and forms a single triloop hairpin. Detailed analysis of the minus-strand pro...

Bamboo mosaic virus (BaMV), which belongs to the genus Potexvirus in the family Alphaflexiviridae, has a single-stranded positive-sense RNA genome that is approximately 6400 nucleotides (nts) in length. Positive-sense RNA viruses can use genomic RNA as a template for translation and replication after entering a suitable host cell. Furthermore, such viral RNA is recognized by capsid protein for ...
متن کاملCoat protein activation of alfalfa mosaic virus replication is concentration dependent.
Alfalfa mosaic virus (AMV) and ilarvirus RNAs are infectious only in the presence of the viral coat protein; therefore, an understanding of coat protein's function is important for defining viral replication mechanisms. Based on in vitro replication experiments, the conformational switch model states that AMV coat protein blocks minus-strand RNA synthesis (R. C. Olsthoorn, S. Mertens, F. T. Bre...
متن کاملRole of the alfalfa mosaic virus methyltransferase-like domain in negative-strand RNA synthesis.
RNAs 1 and 2 of the tripartite genome of alfalfa mosaic virus (AMV) encode the replicase proteins P1 and P2, respectively. P1 contains a methyltransferase-like domain in its N-terminal half, which has a putative role in capping the viral RNAs. Six residues in this domain that are highly conserved in the methyltransferase domains of alphavirus-like viruses were mutated individually in AMV P1. No...

Genomic RNA of positive-strand RNA viruses replicate via complementary (i.e., negative-strand) RNA in membrane-bound replication complexes. Before replication complex formation, virus-encoded replication proteins specifically recognize genomic RNA molecules and recruit them to sites of replication. Moreover, in many of these viruses, selection of replication templates by the replication protein...
