New closterovirus in ‘Redglobe’ grape causes decline of grafted plants [PDF]
In California, first-generation table grape vineyards were planted on their own roots. But in recent years growers have been replanting onto acreage previously in grapes more often.

Suppression of Potyvirus Infection by Coexpressed Closterovirus Protein
A tobacco etch virus (TEV)-based expression vector has been used for insertion of several ORFs derived from the unrelated beet yellows virus (BYV). Hybrid TEV variants expressing the BYV capsid protein, 20-kDa protein, or HSP70 homolog systemically infected Nicotiana tabacum and stably retained BYV sequences.

Genetic Analysis of the Cell-to-Cell Movement of Beet Yellows Closterovirus
A beet yellows closterovirus (BYV) variant expressing green fluorescent protein and leaves of BYV local lesion host Claytonia perfoliata were used to reveal genetic requirements for BYV cell-to-cell movement in leaf epidermis and mesophyll. A series of mutations targeting genes that are not involved in amplification of the viral positive-strand RNA was

Comparative small RNA profiles of beet mosaic virus (BtMV), beet mild yellowing virus (BMYV) and beet yellows virus (BYV) infected Nicotiana benthamiana and Beta vulgaris [PDF]
Plants are constantly challenged by viral pathogens that can limit growth and reduce yield. A key component of the plant innate immunity is RNA silencing, in which viral double-stranded RNA (dsRNA) intermediates are recognised and processed into virus ...

Subcellular Localization of the HSP70-Homolog Encoded by Beet Yellows Closterovirus
Closteroviridae is the only viral family coding for a homolog of HSP70 (HSP70h). Polyclonal antiserum to recombinant beet yellows closterovirus (BYV) HSP70h was generated and used for immunogold labeling of the leaf samples derived from the infected Nicotiana benthamiana plants.

A Chronological Study on Grapevine Leafroll-Associated Virus 2 in Australia [PDF]
Grapevine leafroll disease affects the health status of grapevines worldwide. Most studies in Australia have focused on grapevine leafroll-associated viruses 1 and 3, while little attention has been given to other leafroll virus types, in particular ...

The citrus tristeza virus p33 protein functions as a viroporin. [PDF]
Viroporins are viral proteins that form ion channels in the membranes of the host and, thus, alter the host ion homeostasis to create more favorable environments for the virus.

Effects of rugose wood and GLRaV-1 on yield of cv. ‘Refošk’ grapevines
The influences of rugose wood (RW) disease and grapevine leafroll associated Closterovirus 1 (GLRaV-1) on yield in grapevine cv. Refošk were studied. Both diseases were shown to reduce the yield.

Citrus tristeza virus p20 suppresses antiviral RNA silencing by co-opting autophagy-related protein 8 to mediate the autophagic degradation of SGS3. [PDF]
Viruses exploit autophagy to degrade host immune components for their successful infection. However, how viral factors sequester the autophagic substrates into autophagosomes remains largely unknown.

Characterization of the 3′ proximal gene of the citrus tristeza closterovirus genome
The 3' proximal open reading frame (ORF 11) in the citrus tristeza virus (CTV) genome potentially encodes a protein of 209 amino acids with an estimated molecular weight of 23 kDa (p23). The p23 ORF from the severe Florida strain T36 of CTV was expressed in Escherichia coli, and the expressed protein was used to raise polyclonal antibodies in a rabbit.
