Herpes simplex virus 1 (HSV-1) unspliced 8.3 latency associated transcript (LAT), which located in the long repeat sequences, has been shown to contain at least 16 open reading frames (ORF: A-P). One of these ORF, ORF P, maps almost entirely antisense to HSV-1 neurovirulence gene, ICP34.5. Both ORF P and ICP34.5 are located in the long repeat and are antisense overlapping genes. Therefore, in O...
A 6.4 kb region from the Lymantria dispar multicapsid nuclear polyhedrosis virus (LdMNPV) genome was sequenced and found to contain open reading frames (ORFs) homologous to the polyhedron envelope (PE) protein coding sequence, and the C-terminal half of ORF 1, which is a gene located upstream of the PE protein gene in other baculoviruses. The proteins predicted from the LdMNPV genes encoding th...
Transformed Arabidopsis plants were used to study the effect of the cauliflower mosaic virus (CaMV) inclusion body protein on translation of dicistronic RNA. Reporter plants contain a dicistronic transcription unit with CaMV open reading frame VII (ORF VII) as the first and the [beta]-glucuronidase (GUS) reporter ORF as the second cistron. "Transactivator plants" contain CaMV ORF VI under the c...
The family Potyviridae includes >30% of known plant virus species, many of which are of great agricultural significance. These viruses have a positive sense RNA genome that is approximately 10 kb long and contains a single long ORF. The ORF is translated into a large polyprotein, which is cleaved into approximately 10 mature proteins. We report the discovery of a short ORF embedded within the P...
Cryphonectria hypovirus 1 (CHV1), associated with the picorna-like superfamily, infects the chestnut blight fungus and attenuates the virulence of the host fungus. The genomic RNA of the virus has two continuous open reading frames, A and B, separated by the pentanucleotide UAAUG. We present here evidence suggesting that ORF B is translated from genome-sized virus mRNA by a coupled termination/...
The genomic region encompassing the L protein gene and a small open reading frame (ORF 6) of Rice yellow stunt virus (RYSV) has been sequenced, thus completing the nucleotide sequence of the RYSV genome. The genome organization of RYSV is unique in the rhabdoviruses because it contains two additional genes when compared to the basic gene order of the family Rhabdoviridae: Phylogenetic analysis ...
In this study, a TaqMan real-time polymerase chain reaction (PCR) assay was developed to detect and quantify orf virus (ORFV) DNA in infected cell culture and clinical samples. Primers and probes were designed to amplify an 87 bp fragment DNA based on the sequence of ORFV024 gene encoding an NF-κB inhibitor of orf virus. The assay was highly specific and sensitive for ORFV DNA and no cross-reac...
Jena virus (JV) is a noncultivatable bovine enteric calicivirus associated with diarrhea in calves and was first described in Jena, Germany. The virus was serially passaged 11 times in colostrum-deprived newborn calves and caused diarrheal disease symptoms at each passage. The complete JV genome sequence was determined by using cDNA made from partially purified virus obtained from a single stoo...
The influenza C virus CM2 protein is a small glycosylated integral membrane protein (115 residues) that spans the membrane once and contains a cleavable signal sequence at its N terminus. The coding region for CM2 (CM2 ORF) is located at the C terminus of the 342-amino acid (aa) ORF of a colinear mRNA transcript derived from influenza C virus RNA segment 6. Splicing of the colinear transcript i...
Isolates of hepatitis E virus (HEV) have recently been described from China that are distinct from Burmese, Mexican and US viruses and constitute a novel genotype (genotype 4). Here, the complete genomic sequence of a representative isolate of genotype 4 HEV, amplified directly from the stool of an acutely infected patient, is presented. Analysis of the entire sequence confirms our previous con...
