Classification

This is a description of a plant virus at the species level.

ICTVdB Virus Code: 00.017.0.01.001. Virus accession number: 17001001. Obsolete virus code: 17.0.1.0.001; superceded accession number: 17010001.

Name, Synonyms and Lineage

ICTV approved acronym: BYV. Virus is the type of the genus 00.017.0.01. Closterovirus in the family 00.017. Closteroviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. The capsid is filamentous and very flexuous with a length of 1200-2000 nm and a width of 10-13 nm. Pitch of helix is 3.4-3.7 nm.

Nucleic Acid

The Mr of the genome constitutes 5% of the virion by weight. The genome is monopartite, only one particle size is recovered of linear, positive-sense, single-stranded RNA. The complete genome is 7500-19500 nucleotides long, is fully sequenced. Sequence has the accession number [X73476]. The genome sequence has termini with potential hairpin structure (near 3'-end). The 5'-end of the genome has a probably methylated nucleotide cap.

DELTA - DEscription Language for TAxonomy developed by Dr Mike Dallwitz, Toni Paine and Eric Zurcher, CSIRO Entomology, Canberra, Australia. ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses by Dr Cornelia Büchen-Osmond is written in DELTA. The virus descriptions in ICTVdB are coded by, or using data from experts in the field of virology or members ICTV. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations are automatically generated and formatted for display on the Web from the descriptions in DELTA-format. The description has been generated automatically from DELTA files.
