2018–2019 Florida Citrus Production Guide: Exocortis, Cachexia, and Other Viroids

open access: yesEDIS, 2018
Exocortis and cachexia are diseases caused by viroids, which can lead to stunted growth and reduced yields in affected plants. Viroids are small, low-molecular-weight, infectious RNA molecules.

Towards the validation of high-throughput sequencing (HTS) for routine plant virus diagnostics: measurement of variation linked to HTS detection of citrus viruses and viroids

open access: yesVirology Journal, 2021
High-throughput sequencing (HTS) has been applied successfully for virus and viroid discovery in many agricultural crops leading to the current drive to apply this technology in routine pathogen detection.

An Inside Look into Biological Miniatures: Molecular Mechanisms of Viroids

open access: yesInternational Journal of Molecular Sciences, 2021
Viroids are tiny single-stranded circular RNA pathogens that infect plants. Viroids do not encode any proteins, yet cause an assortment of symptoms. The following review describes viroid classification, molecular biology and spread.

Viroids as a Tool to Study RNA-Directed DNA Methylation in Plants

open access: yesCells, 2021
Viroids are plant pathogenic, circular, non-coding, single-stranded RNAs (ssRNAs). Members of the Pospiviroidae family replicate in the nucleus of plant cells through double-stranded RNA (dsRNA) intermediates, thus triggering the host’s RNA interference (

Transformation of Seed Non-Transmissible Hop Viroids in Nicotiana benthamiana Causes Distortions in Male Gametophyte Development

open access: yesPlants, 2021
Viroids are small, non-coding, parasitic RNAs that promote developmental distortions in sensitive plants. We analyzed pollen of Nicotiana benthamiana after infection and/or ectopic transformation with cDNAs of citrus bark cracking viroid (CBCVd), apple ...

Precisely Monomeric Linear RNAs of Viroids Belonging to Pospiviroid and Hostuviroid Genera Are Infectious Regardless of Transcription Initiation Site and 5′-Terminal Structure

open access: yesCells, 2021
Infectious dimeric RNA transcripts are a powerful tool for reverse genetic analyses in viroid studies. However, the construction of dimeric cDNA clones is laborious and time consuming, especially in mutational analyses by in vitro mutagenesis.

Field detection of multiple RNA viruses/viroids in apple using a CRISPR/Cas12a‐based visual assay

open access: yesPlant Biotechnology Journal, 2020
Summary Co‐infection of apple trees with several viruses/viroids is common and decreases fruit yield and quality. Accurate and rapid detection of these viral pathogens helps to reduce losses and prevent virus spread.

The viroid and viroid-like RNA database [PDF]

open access: yesNucleic Acids Research, 1999
This is an online database to facilitate research on viroid, viroid-like RNAs and human hepatitis delta virus (vHDV) by presenting a large number of sequences and related data in a comprehensive and user-friendly format (e.g. position of their self-catalytic domains, open reading frame of the vHDV, prediction of the most stable secondary structures ...

RNA‐dependent RNA polymerase 1 delays the accumulation of viroids in infected plants

open access: yesMolecular plant pathology, 2021
RNA‐dependent RNA polymerase 1 (RDR1) is essential for plant antiviral defence, but its role in plant defence against viroid infection remains unknown. The present study aimed to identify the function and mechanism of RDR1 in plant resistance to viroid ...

Mexican papita viroid: putative ancestor of crop viroids. [PDF]

open access: greenProceedings of the National Academy of Sciences, 1996
The potato spindle tuber disease was first observed early in the 20th century in the northeastern United States and shown, in 1971, to be incited by a viroid, potato spindle tuber viroid (PSTVd). No wild-plant PSTVd reservoirs have been identified; thus, the initial source of PSTVd infecting potatoes has remained a mystery.
