. 2019 Mar;
88(7):709-713.
PMID: 30812480
The unusual symptom, "finger imprint", described exclusively on Poncirus trifoliata, has been reported in only a single field trial investigating the effects of citrus viroids on crop performance. With this,...

PMID: 18944692
ABSTRACT Citrus viroid (CVd) group II is comprised of hop stunt viroid (HSVd)-related variants of 295 to 302 nucleotides. Included in this group are the cachexia-inducing agents citrus cachexia viroid...

Arch Virol
. 2005 Apr;
150(6):1059-67.
PMID: 15821974
It has been suggested that Citrus viroid IV (CVd-IV) be classified as a species within the genus Cocadviroid. This relationship was based on the presence of a terminal conserved hairpin...

PMID: 15659768
Prolonged infection of tomato hybrid (Lycopersicon esculentum x Lycopersicon peruvianum) by Citrus exocortis viroid (CEVd) resulted in viroid-like enlarged structures, detected by gel electrophoresis. This population included two new enlarged...

149(2):397-406.
PMID: 14745603
Evidence of post-transcriptional gene silencing (PTGS) in avocado infected by Avocado sunblotch viroid (ASBVd), the type species of family Avsunviroidae, was suggested by detection of ASBVd-specific 22-nucleotide RNAs. PTGS was...

Virology
. 2001 Feb;
280(1):115-23.
PMID: 11162825
Natural selection of two new variants of citrus exocortis viroid (CEVd) was detected by observing tissues displaying both severe and mild symptoms from a single Gynura aurantiaca. The variants CEVd-S...

J Gen Virol
. 1999 Jan;
79 ( Pt 12):3163-71.
PMID: 9880036
Nucleotide sequences were determined for two hop stunt viroid-related Group II citrus viroids characterized as either a cachexia disease non-pathogenic variant (CVd-IIa) or a pathogenic variant (CVd-IIb). Sequence identity between...

Szychowski J, Credi R, Reanwarakorn K, Semancik J
Virology
. 1998 Aug;
248(2):432-44.
PMID: 9721250
Vitis vinifera cultivars Zinfandel-1A and Mission were found to harbor different grapevine yellow speckle viroid-1 (GYSVd-1) variants and characterized to define the relationship to yellow speckle (YS) and vein-banding (VB)...
