ICTV Virus Taxonomy Profile: Closteroviridae
Journal of General Virology, 2020 Viruses in the family Closteroviridae have a mono-, bi- or tripartite positive-sense RNA genome of 13–19 kb, and non-enveloped, filamentous particles 650–2200 nm long and 12 nm in diameter. They infect plants, mainly dicots, many of which are fruit crops.

Functional Specialization and Evolution of Leader Proteinases in the Family Closteroviridae [PDF]
Journal of Virology, 2001 ABSTRACT Members of the Closteroviridae and Potyviridae families of the plant positive-strand RNA viruses encode one or two papain-like leader proteinases. In addition to a C-terminal proteolytic domain, each of these proteinases possesses a nonproteolytic N-terminal domain.

Characterization of a Novel Member of the Family Closteroviridae from Mentha spp. [PDF]
Phytopathology®, 2005 While characterizing the agents involved in symptomatology of a variegated mint, Mentha × gracilis ‘Variegata’, a nursery plant with atypical symptoms was examined. This plant, unlike ‘Variegata’, did not exhibit yellow vein banding symptoms but instead had distorted and crinkled leaves.

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 ...

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.

Molecular characterization of closteroviruses infecting Cordyline fruticosa L. in Hawaii
Frontiers in Microbiology, 2013 In Hawaii, common green ti plants (Cordyline fruticosa L.) have been shown to harbor Cordyline virus 1 (CoV-1) which, along with Little cherry virus 1 (LChV-1) and Grapevine leafroll-associated virus 7 (GLRaV-7), form a distinct clade within the family ...
