the genome of iranian wheat stripe virus (iwsv), a tentative member of the genus tenuivirus, is comprised of three ambisense and one negative sense rna segments. the coat and non-structural proteins encoded by the vcrna3 and vrna4 genes, respectively, were efficiently translated in vitro. translated proteins of vcrna3 and vrna4 transcripts were approximately 35000 and 22000 in mr, respectively,...

The Phlebovirus genus (family Bunyaviridae) is composed of a diverse group of arboviruses that cause disease syndromes ranging from mild febrile illness to hemorrhagic fever with high fatality. Although antigenically similar, these viruses differ by approximately 25% at the genome level, and their ecologies, including geographic ranges, preferred vector species, and hosts, vary considerably. In...
The complete nucleotide sequence of rice stripe virus (RSV) segment 3 shows that it has two open reading frames, one in the viral-complementary sequence, which codes for the nucleocapsid protein, and the other in the viral-sense sequence. The non-coding region between the ambisense genes in RSV segment 3 contains several U and A tracts, as do the ambisense S segments of phleboviruses and uukuvi...
UNLABELLED We generated a recombinant Akabane virus (AKAV) expressing enhanced green fluorescence protein (eGFP-AKAV) by using reverse genetics. We artificially constructed an ambisense AKAV S genome encoding N/NSs on the negative-sense strand, and eGFP on the positive-sense strand with an intergenic region (IGR) derived from the Rift Valley fever virus (RVFV) S genome. The recombinant virus ex...
UNLABELLED The Bunyamwera (BUNV) orthobunyavirus NSs protein has proven a challenge to study in the context of viral infection. NSs is encoded in a reading frame that overlaps that of the viral nucleocapsid (N) protein thus limiting options for mutagenesis. In addition, NSs is poorly immunogenic, and antibodies only work in certain techniques while the protein itself is subject to proteasomal d...
Bunyamwera virus (BUNV) is the prototype of the Bunyaviridae family of RNA viruses. BUNV genomic strands are templates for both replication and transcription, whereas the antigenomic RNAs serve only as templates for replication. By mutagenesis of model templates, we showed that the BUNV transcription promoter comprises elements within both the 3' and the 5' nontranslated regions. Using this inf...
The role of the variable portion of the noncoding regions (NCRs) of the three Bunyaviridae RNA segments (L, M, S) in transcription, replication, and packaging was studied using the recently developed plasmid-driven RNA polymerase I minigenome system for Uukuniemi (UUK) virus, genus Phlebovirus (11), as a model. Comparison of the different segments showed that all NCRs were sufficient to mediate...
The genome of a densovirus of a major phytophagous pest, Pseudoplusia includens, was analyzed. It contained 5,990 nucleotides (nt) and included inverted terminal repeats of 540 nt with terminal Y-shaped hairpins of 120 nt. Its DNA sequence and ambisense organization with 4 typical open reading frames demonstrated that it belonged to the genus Densovirus in the subfamily Densovirinae of the fami...
