A conserved hairpin structure in Alfamovirus and Bromovirus subgenomic promoters is required for efficient RNA synthesis in vitro. (1/3)

The coat protein gene in RNA 3 of alfalfa mosaic virus (AMV; genus Alfamovirus, family Bromoviridae) is translated from the subgenomic RNA 4. Analysis of the subgenomic promoter (sgp) in minus-strand RNA 3 showed that a sequence of 37 nt upstream of the RNA 4 start site (nt +1) was sufficient for full sgp activity in an in vitro assay with the purified viral RNA-dependent RNA-polymerase (RdRp). The sequence of nt -6 to -29 could be folded into a potential hairpin structure with a loop represented by nt -16, -17, and -18, and a bulge involving nt -23. By introducing mutations that disrupted base pairing and compensatory mutations that restored base pairing, it was shown that base pairing in the top half of the putative stem (between the loop and bulge) was essential for sgp activity, whereas base pairing in the bottom half of the stem was less stringently required. Deletion of the bulged residue A-23 or mutation of this residue into a C strongly reduced sgp activity, but mutation of A-23 into U or G had little effect on sgp activity. Mutation of loop residues A-16 and A-17 affected sgp activity, whereas mutation of U-18 did not. Using RNA templates corresponding to the sgp of brome mosaic virus (BMV; genus Bromovirus, family Bromoviridae) and purified BMV RdRp, evidence was obtained indicating that also in BMV RNA a triloop hairpin structure is required for sgp activity.  (+info)

Antigens produced in plants by infection with chimeric plant viruses immunize against rabies virus and HIV-1. (2/3)

The coat protein (CP) of alfalfa mosaic virus was used as a carrier molecule to express antigenic peptides from rabies virus and HIV. The antigens were separately cloned into the reading frame of alfalfa mosaic virus CP and placed under the control of the subgenomic promoter of tobacco mosaic virus CP in the 30BRz vector. The in vitro transcripts of recombinant virus with sequences encoding the antigenic peptides were synthesized from DNA constructs and used to inoculate tobacco plants. The plant-produced protein (virus particles) was purified and used for immunization of mice. Both antigens elicited specific virus-neutralizing antibodies in immunized mice.  (+info)

Tubule-forming capacity of the movement proteins of alfalfa mosaic virus and brome mosaic virus. (3/3)

The structural phenotype of the movement proteins (MPs) of two representatives of the Bromoviridae, alfalfa mosaic virus (AMV) and brome mosaic virus (BMV), was studied in protoplasts. Immunofluorescence microscopy showed that the MPs of these viruses, for which there has been no evidence of a tubule-guided mechanism, assemble into long tubular structures at the surface of the infected protoplast. Electron microscopy and immunogold analysis confirmed the presence of both MP and virus particles in the tubules induced by AMV and BMV. The significance of the tubule-forming properties of these viral MPs is discussed.  (+info)

387440791 - EP 0832191 A4 2000-11-15 - RECOMBINANT VIRAL NUCLEIC ACIDS - [origin: WO9640867A1] The present invention relates to a recombinant viral nucleic acid selected from a (+) sense, single stranded RNA virus possessing a native subgenomic promoter encoding for a first viral subgenomic promoter, a nucleic acid sequence that codes for a viral coat protein whose transcription is regulated by the first viral subgenomic promoter, a second viral subgenomic promoter and a second nucleic acid sequence whose transcription is regulated by the second viral subgenomic promoter. The first and second viral subgenomic promoters of the recombinant viral nucleic acid do not have homologous sequences relative to each other. The recombinant viral nucleic acid provides the particular advantage that it systematically transcribes the second nucleic acid in the host. Host organisms encompassed by the present invention include procaryotes and eucaryotes, particularly animals and plants. The present invention also relates
