The two segments of double-stranded RNA (dsRNA) from
infectious pancreatic necrosis virus (IPNV) were cloned
into plasmid vector pUC8. Two distinct sets of overlapping
clones were identified by restriction enzyme and Southern
blot analysis. Each of these sets was shown, by Northern
blot analysis, to be exclusively related to either...
Turnip yellow mosaic virus is a monopartite, plus sense RNA virus
infecting the Cruciferae, and is a model system for the study of RNA virus
replication. A cDNA clone (pTYMC) representing an infectious RNA
genome of the European isolate of TYMV was constructed and used to assess
the importance of...
Beet yellows virus (BYV) is a filamentous, positive-strand RNA virus that belongs to the family Closteroviridae. BYV particles encapsidate a 15.5 kb RNA and posses complex polar architecture. A long virion body is formed by the major capsid protein(CP), whereas the minor capsid protein (CPm) assembles a short tail that...
Bovine viral diarrhea virus (BVDV) is an enveloped, single-stranded positive-sense RNA virus. The BVDV genome is about 12.5 kb long and consists of a single open reading frame (ORF) flanked by untranslated regions at the 5' and 3' ends (5'-UTR and 3'- UTR, respectively). To investigate the role of cis-sequences...
