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, the question has persisted whether the

The term ‘transmissible small nuclear ribonucleic acids' (TsnRNAs) describes well-characterised viroid RNA species that do not induce any pronounced disease syndromes in specific citrus hosts, but rather act as regulatory genetic elements modifying

Summary The citrus viroid II (CVd-II, Hop stunt viroid) variant, cachexia 909 (Ca-909) has been designated as a “cachexia” disease isolate on the basis of inducing extremely mild symptoms on the cachexia indexing host Parson's Special mandarin (P

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 (TCH) and absence of a terminal conserved region (TCR) as specif

A viroid etiology for citrus gummy bark (CGB) disease of sweet orange is supported by the similarity of symptom expression to cachexia disease of mandarins and tangelos caused by the hop stunt viroid (HSVd) related citrus viroid II (CVd-II), as well

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 (severe) and CEVd-M (mild), differing by only five

SUMMARY Description of a cachexia disease specific oligonucleotide is presented which may be employed as a probe in molecular hybridisation as well as a primer in reverse transcriptase-polymerase chain reaction (RT-PCR) procedures to segregate cachex

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 the two variants of

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) diseases. Products from th
