Sequence of Echinochloa hoja blanca tenuivirus RNA-5

Virus Genes, 1996
The sequence is presented of RNA-5 of Echinochloa hoja blanca tenuivirus, a second tenuivirus associated with rice cultivation in Latin America (after rice hoja blanca virus). The RNA is 1334 nucleotides long and contains in the complementary sense RNA a single long open reading frame.

Sequence of Echinochloa hoja blanca tenuivirus RNA-4

Virus Genes, 1996
The sequence is presented of RNA-4 of Echinochloa hoja blanca tenuivirus (EHBV), one of two tenuiviruses associated with rice cultivation in Latin America (together with rice hoja blanca virus; RHBV). Analysis of the sequence shows that the coding regions of EHBV RNA-4 are closely related to those of RHBV RNA-4.

Sequence of Echinochloa hoja blanca tenuivirus RNA-3

Virus Genes, 1996
Analysis of the sequence of the 2336 nucleotide RNA-3 of Echinochloa hoja blanca tenuivirus shows that it is closely related to RNA-3 of rice hoja blanca tenuivirus, the principal virus disease of rice in Latin America. This is especially true for the coding regions, where the viruses are almost 90% similar.

Sequence of the PV2 gene of rice hoja blanca tenuivirus RNA-2

Virus Genes, 1995
Comparison of a partial sequence of rice hoja blanca tenuivirus RNA-2 with 40% similarity to rice stripe tenuivirus RNA-2 revealed regions of high local sequence homology at the 5' terminus, within the coding region (the pv2 gene), and in the intergenic region separating this gene from the other protein (pc2) encoded by this ambisense RNA.

Transcription start site mapping of geminiviruses using the in vitro cap-snatching of a tenuivirus

Journal of Virological Methods, 2023
Geminiviruses are a family of single-stranded DNA viruses that cause significant yield losses in crop production worldwide. Transcription start site (TSS) mapping is crucial in understanding the gene expression mechanisms of geminiviruses. However, this often requires costly and laborious experiments.

Rapid, small scale purification of rice hoja blanca and Echinochloa hoja blanca tenuivirus ribonucleoprotein

Journal of Virological Methods, 1996
Highly purified tenuivirus ribonucleoprotein was obtained from small amounts of leaf tissue by sedimenting the ribonucleoprotein particles from debris-free plant extract into a 30% sucrose cushion, in 1.5-mL microfuge tubes. Using this protocol, significant size differences were discovered in the double-stranded forms of the viral genomic RNAs of rice ...

BIOLOGY AND MOLECULAR BIOLOGY OF VIRUSES IN THE GENUS TENUIVIRUS

Annual Review of Phytopathology, 1998
▪ Abstract  Viruses in the genus Tenuivirus (Tenuiviruses) cause a number of important diseases in economically important crop plants including rice and maize. Tenuiviruses are transmitted from plant to plant by specific planthopper vectors, and their transmission relationship is circulative-propagative.

Genomic and phylogenetic characterization of wheat yellows virus, a novel tenuivirus infecting wheat in South Africa

Archives of Virology, 2022
During the 2019 winter wheat season, symptoms of severe chlorosis and stunting were observed on wheat in the irrigation production areas of South Africa. RNAtag-seq data were generated for seven samples from KwaZulu-Natal province and one from Limpopo.

Transcription of ORFs on RNA2 and RNA4 of Rice stripe virus terminate at an AUCCGGAU sequence that is conserved in the genus Tenuivirus

Virus Research, 2013
Rice stripe virus, the type member of the genus Tenuivirus, has four genomic RNAs. RNAs 2-4 have an ambisense coding strategy and the noncoding intergenic regions (IRs) separating the two ORFs are thought to function in termination of transcription. Sequencing the 3'-untranslated region of transcripts from RNA2 and RNA4 in virus-infected Oryza sativa ...

Comparison of Colombian and Costa Rican Strains of Rice Hoja Blanca Tenuivirus

Virus Genes, 1997
The sequences of RNA-3 and RNA-4 of rice hoja blanca tenuivirus isolates from Colombia and from Costa Rica were determined and analyzed. These isolates were 98.9% and 98.6% identical in the coding and non-coding regions of RNA-3, and 96.9 and 91.5% identical in the coding and non-coding regions of RNA-4, and are therefore strains of the same virus ...
