The small size and noncoding nature of viroid RNAs raises intriguing and specific questions about how they induce disease. The absence of viroid-encoded proteins, in sharp contrast to viruses, led originally to the assumption that viroid diseases were the result of direct interaction of the genomic viroid RNA (or its complement) with cellular ...

Viroids are autonomously replicating, small single-stranded circular RNA pathogens that do not code for proteins and may cause diseases in infected, susceptible plants. They have the ability to induce both RNA-mediated transcriptional gene silencing (TGS) and post-transcriptional gene silencing (PTGS), or RNA silencing, in infected plants.

CITRUS VIROIDS IN TUNISIA: PREVALENCE AND MOLECULAR CHARACTERIZATION
, 2017A field survey was conducted in commercial orchards of Cap Bon region and at the INRAT citrus collection to identify the prevalence of citrus viroids in Tunisia. Samples were collected from 202 trees grafted on sour orange (Citrus aurantium L.) including

Dynamics and Interactions of Viroids
Journal of Biomolecular Structure and Dynamics, 1983Viroids are single stranded circular RNA molecules of 120,000 daltons which are pathogens of certain higher plants and replicate autonomously in the host cell. Virusoids are similar to viroids in respect to size and circularity but do replicate only as a part of a larger plant virus.

Origin and evolution of viroids and viroid-like satellite RNAs
Virus Genes, 1995Viroids, the smallest and simplest agents of infectious disease, cause a number of economically important diseases of crop plants. Present evidence indicates that most of these diseases originated recently (in the 20th century) by chance transfer of viroids from endemically infected wild plants or by use of viroid-infected germplasm during plant ...

Cloning and Sequencing of Viroids
2021Determining the sequence identity of viroid RNAs present in symptomatic or asymptomatic plant tissues is critical to obtain knowledge of their distribution. It enables the development of tools for diagnostics and for studying the basic biology of viroids.

Chapter 5 in the book Viroids and Satellites is entiteled Viroid Biology. The biology of viroids is a wide term encompassing biological phenomena exerted by these noncoding, 246-401-nts long, single-stranded circular RNAs. As viroids interfere with plant transcription and trafficking machinery, the term commonly comprises plant host range ...
