tRNA-like structure regulates translation of Brome mosaic virus RNA.
For various groups of plant viruses, the genomic RNAs end with a tRNA-like structure (TLS) instead of the 3' poly(A) tail of common mRNAs. The actual function of these TLSs has long been enigmatic. Recently, however, it became clear that for turnip yellow mosaic virus, a tymovirus, the valylated TLS(TYMV) of the single genomic RNA functions as a bait for host ribosomes and directs them to the i...
متن کاملEfficient Amplification of Brome Mosaic Virus
The genome of brome mosaic virus (BMV) is divided among messenger polarity RNA1, RNA2, and RNA3 (3.2, 2.9, and 2.1 kilobases, respectively). cis-Acting sequences required for BMV RNA amplification were investigated with RNA3. By using expressible cDNA clones, deletions were constructed throughout RNA3 and tested in barley protoplasts coinoculated with RNA1 and RNA2. In contrast to requirements ...
متن کاملTubule-forming capacity of the movement proteins of alfalfa mosaic virus and brome mosaic virus.
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 protopla...
متن کاملTelomeric function of the tRNA-like structure of brome mosaic virus RNA.
Four mutant brome mosaic virus (BMV) RNA3 transcripts, bearing single or double base changes in the 3'-CCAOH terminus of the tRNA-like structure, previously characterized as being deficient in vitro with respect to aminoacylation and replication activities, have now been assayed in vivo for their ability to replicate (in the presence of transcripts of wild-type RNA1 and -2) in barley protoplast...
متن کاملEnhancer-like activity of a brome mosaic virus RNA promoter.
As with transcription from DNA templates, RNA synthesis from viral RNA templates must initiate accurately. RNA sequences named specificity and initiation determinants allow recognition of and coordinated interaction with the viral replication enzyme. Using enriched replicase from brome mosaic virus (BMV)-infected plants and variants of the promoter template for minus-strand and subgenomic RNA i...
