Transcription in vitro of infectious haematopoietic necrosis virus, a fish rhabdovirus.
نویسندگان
چکیده
Transcription in vitro by the RNA polymerase of infectious haematopoietic necrosis virus (IHNV), a salmonid rhabdovirus, was investigated using different reaction conditions to maximize RNA synthesis. The use of HEPES buffer rather than Tris buffer, and the addition of S-adenosyl-L-methionine to the reactions resulted in a sixfold increase in RNA synthetic activity to 6400 pmol UMP incorporated/mg viral protein/hour. The RNA transcripts produced in this system contained polyadenylated species which co-migrated with IHNV mRNA species 2, 3, 4 and 5 from IHNV-infected cells. The transcripts were shown to be functional mRNA species by their ability to direct the synthesis of viral proteins in vitro.

Complete genomic sequence of the fish rhabdovirus infectious haematopoietic necrosis virus.
The complete nucleotide sequence of the genome of the fish rhabdovirus infectious haematopoietic necrosis virus (IHNV) has been determined after cDNA cloning of the viral genomic RNA. Sequence analysis showed the presence of six open reading frames encoding the nucleoprotein N, the matrix proteins M1 and M2, the glycoprotein G, a so-called non-structural protein NV, and the RNA polymerase L. Th...

The fish rhabdovirus infectious haematopoietic necrosis virus (IHNV) contains a non-virion (NV) gene between the glycoprotein (G) and polymerase (L) genes on its RNA genome. The present study investigated three other fish rhabdovirus genomes and found that the NV gene of hirame rhabdovirus is closely related to the NV of IHNV, whereas the viral haemorrhagic septicemia NV gene showed evidence of...

Twelve neutralizing monoclonal antibodies (MAbs) against the fish rhabdovirus, infectious haematopoietic necrosis virus (IHNV), were used to select 20 MAb escape mutants. The nucleotide sequence of the entire glycoprotein (G) gene was determined for six mutants representing differing cross-neutralization patterns and each had a single nucleotide change leading to a single amino acid substitutio...

Identification of the non-virion (NV) protein of fish rhabdoviruses viral haemorrhagic septicaemia virus and infectious haematopoietic necrosis virus.
Sequence analysis of a 795 nucleotide region of the fish rhabdovirus viral haemorrhagic septicaemia virus (VHSV) genome revealed one complete and one partial ORF of 369 and 153 nucleotides, respectively. The latter ORF probably encodes the amino-terminal part of the L (polymerase) protein. The former ORF potentially encodes a 122 amino acid protein. The location of this ORF as well as the size ...
