Closteroviridae: a new family of flexous plant viruses

Acta Phytopathologica et Entomologica Hungarica, 2002
Members of the family Closteroviridae have been traditionally defined as plant viruses with thread-like particles having messenger-sense single-stranded RNA, the largest genomes among RNA plant viruses. Individual virus species are distributed worldwide and some of them cause devastating crop losses. The natural host range usually narrow.

La malaltia de l'enrotllament de la fulla de vinya i virus associats [PDF]

, 2015
L'enrotllament de la fulla de la vinya és una malaltia d'origen víric que té un gran impacte negatiu sobre els conreus i la producció de raïm de qualitat. Es coneix des de fa més d'un segle, amb una distribució mundial i amb deu espècies de closterovirus

Variant evidence of three genes of Potato vein yellow virus infecting Solanum tubersosum sp. using single strand conformational polymorphism.

Acta Biológica Colombiana, 2015
Potato yellow vein virus (PYVV) with tripartite RNA (ss+) genome is classified as Crinivirus within the family Closteoviridae. PYVV is the causal agent of potato yellow vein disease (PYVD) with yield effect.

3'-coterminal subgenomic RNAs and putative cis-acting elements of Grapevine leafroll-associated virus 3 reveals 'unique' features of gene expression strategy in the genus Ampelovirus

Virology Journal, 2010
Background The family Closteroviridae comprises genera with monopartite genomes, Closterovirus and Ampelovirus, and with bipartite and tripartite genomes, Crinivirus. By contrast to closteroviruses in the genera Closterovirus and Crinivirus, much less is

Secoviridae: a proposed family of plant viruses within the order Picornavirales that combines the families Sequiviridae and Comoviridae, the unassigned genera Cheravirus and Sadwavirus, and the proposed genus Torradovirus [PDF]

, 2009
The order Picornavirales includes several plant viruses that are currently classified into the families Comoviridae (genera Comovirus, Fabavirus and Nepovirus) and Sequiviridae (genera Sequivirus and Waikavirus) and into the unassigned genera Cheravirus ...

Replication of Lettuce chlorosis virus (LCV), a crinivirus in the family Closteroviridae, is accompanied by the production of LCV RNA 1-derived novel RNAs.

Virology, 2011
Cloned infectious complementary DNAs of the bipartite genomic RNAs of Lettuce chlorosis virus (LCV) were constructed. Inoculation of tobacco protoplasts with the in vitro produced RNAs 1 and 2 transcripts, or with RNA 1 transcript alone, resulted in viral replication accompanied by the production of novel LCV RNA 1-derived RNAs.

The Viral Fraction Metatranscriptomes of Lake Baikal

Microorganisms, 2022
This article characterises viral fraction metatranscriptomes (smaller than 0.2 µm) from the pelagic zone of oligotrophic Lake Baikal (Russia). The study revealed the dominance of transcripts of DNA viruses: bacteriophages and algal viruses. We identified

Extension of the viral ecology in humans using viral profile hidden Markov models. [PDF]

PLoS ONE, 2018
When human samples are sequenced, many assembled contigs are "unknown", as conventional alignments find no similarity to known sequences. Hidden Markov models (HMM) exploit the positions of specific nucleotides in protein-encoding codons in various ...

GATA8-Mediated Antiviral Defence Is Countered by Tomato Chlorosis Virus-Encoded Pathogenicity Protein p27. [PDF]

Mol Plant Pathol
GATA8 enhances the antiviral defence of tomato plants against tomato chlorosis virus by binding to the promoter of SnRK2, thereby regulating its expression. However, this process is counteracted by the viral p27 protein. ABSTRACT Tomato chlorosis virus (ToCV), a phloem‐restricted RNA virus within the genus Crinivirus of the family Closteroviridae ...
