The long flexuous virions of the Closteroviridae have a unique bipolar architecture incorporating two coat proteins, with most of the helical nucleocapsid encapsidated by the major coat protein (CP) and a small portion of one end encapsidated by the minor coat protein (CPm). It is not known whether CPm encapsidates the genomic RNA and, if so, which end and what effects transition between the two coat proteins. Two other virus-encoded proteins, an HSP70 homolog (HSP70h) and an approximately 61…

Closteroviruses possess exceptionally long filamentous virus particles that mediate protection and active transport of the genomic RNA within infected plants. These virions are composed of a long

Closteroviruses: Molecular Biology, Evolution and Interactions with Cells

The genome expression of closteroviruses occurs by proteolytic processing and +1 ribosomal frameshifting for the replication-associated products of the 5′ -proximal genes, whereas the 3′-terminal genes are expressed via a nested set of subgenomic mRNAs, which strikingly resembles the expression strategy of nidovirus.

The minor coat protein of ToCV, which forms part of the “rattlesnake tail” of virions and may be involved in determining the unique, broad vector transmissibility of To CV, is larger than the CPm of lettuce infectious yellows virus (LIYV) by 217 amino acids.

An Analysis of the Complete Genome Sequence and Subgenomic RNAs Reveals Unique Features of the Ampelovirus, Grapevine leafroll-associated virus 1.

This study provided a foundation for further elucidation of the comparative molecular biology of closteroviruses infecting grapevines and developed a reverse transcription-polymerase chain reaction and restriction fragment length polymorphism method to distinguish GLRaV-1 variants in vineyards.

Comparative and functional genomics of closteroviruses

A new closterovirus in Alcea rosea identified by small RNA deep sequencing

Results indicate that Alcea rosea virus 1 is a member of a new species of the genus Closterovirus, which is a conserved and specific degradation mechanism of a target RNA by virus-derived small interfering RNAs in eukaryotic organisms.



Closterovirus encoded HSP70 homolog and p61 in addition to both coat proteins function in efficient virion assembly.

The involvement of gene products of Citrus tristeza virus (CTV) in virion formation was examined and it was found that the chaperone-like protein plus the p61 and both coat proteins were required for efficient virion assembly.

The minor coat protein of beet yellows closterovirus encapsidates the 5' terminus of RNA in virions.

Data clearly indicate that it is the 5'-terminal portion of the closterovirus RNA genome that is encapsidated by p24, and the [gamma-32P]ATP-labelled RNA obtained from the antibody-selected particle segments consistently showed stronger hybridization with the 5'terminal BYV cDNA clones than with the 3'-terminals cDNA clone.

The 64-Kilodalton Capsid Protein Homolog of Beet Yellows Virus Is Required for Assembly of Virion Tails

The dual function of p64 in tail assembly and BYV motility is revealed and the concept of the virion tail as a specialized device for BYV cell-to-cell movement is supported.

Nucleotide sequence and organization of eight 3' open reading frames of the citrus tristeza closterovirus genome.

A specific four-gene module consisting of thehsp70 protein, the hsp90-related protein, a diverged copy of the CP, and the CP itself was found to be common in organization between CTV and beet yellows closterovirus, indicating that these viruses probably have evolved from a common ancestor.

Characterization of the cis-acting elements controlling subgenomic mRNAs of citrus tristeza virus: production of positive- and negative-stranded 3'-terminal and positive-stranded 5'-terminal RNAs.

Citrus tristeza virus has an approximately 20-kb positive-sense RNA genome with two 5' ORFs translated from the genomic RNA and 10 3' genes expressed via nine or ten 3'-terminal subgenomic RNAs, which theoretically could produce 30-33 species of RNAs in infected cells.

Hepadnavirus assembly and reverse transcription require a multi‐component chaperone complex which is incorporated into nucleocapsids

A model for hepadnavirus assembly and priming of viral DNA synthesis is proposed where a dynamic, energy‐driven process, mediated by a multi‐component chaperone complex consisting of Hsp90, p23 and, potentially, additional factors, maintains the reverse transcriptase in a specific conformation that is competent for RNA packaging and protein priming on pregenomic RNA.

Cell‐to‐cell movement and assembly of a plant closterovirus: roles for the capsid proteins and Hsp70 homolog

A dual role for the viral molecular chaperone Hsp70h in virion assembly and transport, combined with the previous finding of this protein in intercellular channels, allowed this work to propose a model of closteroviral movement from cell to cell.

Effects of Modification of the Transcription Initiation Site Context on Citrus Tristeza Virus Subgenomic RNA Synthesis

Based on results, the CTV replication complex appears to initiate sgRNA synthesis with purines, preferably with adenylates, and is able to initiate synthesis using a nucleotide a few positions 5′ or 3′ of the native initiation nucleotide.

"Rattlesnake" structure of a filamentous plant RNA virus built of two capsid proteins.

A 75-nm segment at one end of the 1370-nm filamentous viral particle was found to be consistently labeled with both types of antibodies, thus indicating that p24 is indeed the second capsid protein and that the closterovirus particle, unlike those of other plant viruses with helical symmetry, has a "rattlesnake" rather than uniform structure.
