Viromics reveals two novel viruses of the family Closteroviridae in Codiaeum variegatum plant with leaf variegation symptoms.

Plant Disease
Codiaeum variegatum is a valuable ornamental plant with distinct bright yellowing and golden spots on dark green leaves, which resemble virus symptoms.

Closteroviridae [PDF]

Virus Taxonomy, 2011
This chapter focuses on Closteroviridae family whose member genuses are Closterovirus, Ampelovirus, and Crinivirus. The virions are helically constructed filaments with a pitch of the primary helix in the range of 3.4–3.8 nm, containing about 10 protein subunits per turn of the helix and showing a central hole of 3–4 nm.

A Brief Historical Account of the Family Closteroviridae.

Methods in molecular biology, 2019
The history is outlined of the steps that, starting from the establishment of the "taxonomic group Closterovirus," have brought to the erection of the family Closteroviridae, a taxon comprising plant viruses that possess very long helically constructed filamentous particles and a positive-sense single-stranded, monopartite or bipartite RNA genome and ...

Characterization of Actinidia virus 1, a new member of the family Closteroviridae encoding a thaumatin-like protein

Archives of Virology, 2017
A new member of the family Closteroviridae was detected in Actinidia chinensis grown in Italy, using next generation sequencing of double-stranded RNA. The virus isolate, named Actinidia virus 1 (AcV-1) has a genome of 18,848 nts in length, a structure similar to the unclassified persimmon virus B (PeVB) and contains 12 open reading frames (ORFs ...

The family Closteroviridae revised

Archives of Virology, 2002
Molecular and biological information has prompted the revision of the taxonomic structure of the family Closteroviridae. In particular, mealybug-transmitted species have been separated from the genus Closterovirus and accommodated in a new genus named Ampelovirus (from ampelos, Greek for grapevine). Thus, the familynow comprises three genera.

A Closterovirus (Family: Closteroviridae) Isolated from Tobacco Crops in Northern Greece (Macedonia).

Plant Disease, 1999
In 1997, viruslike symptoms similar to those caused by potato potyvirus Y (PVY) were observed in tobacco (Nicotiana tabacum ) plants of the cv. Basmas in the area of Drama (Macedonia) in northern Greece. Diseased plants showed vein clearing and necrosis of the petioles and main veins, and were severely stunted.

Genome organization and phylogenetic relationship of Pineapple mealybug wilt associated virus-3 with family Closteroviridae members

Virus Genes, 2009
The nucleotide sequence of Pineapple mealybug wilt associated virus-3 (PMWaV-3) (Closteroviridae: Ampelovirus), spanning seven open reading frames (ORFs) and the untranslatable region of the 3' end was determined. Based on the amino acid identities with orthologous ORFs of PMWaV-1 (54%-73%) and PMWaV-2 (13%-35%), we propose PMWaV-3 is a new species in ...

A Member of the Closteroviridae from Mint with Similarities to All Three Genera of the Family. [PDF]

Plant Disease, 2005
Mentha × gracilis ‘Variegata’, described more than 200 years ago, is still being used as an ornamental. The bright vein-banding symptoms that confer the ornamental value to ‘Variegata’ clones are graft transmissible and can be eliminated after heat therapy and apical meristem culture.
