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.

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 ...

Is the Scrapie Agent a Viroid?
Nature New Biology, 1972RECENT evidence indicates that the agent of the potato spindle tuber disease, previously thought to be a virus, is a replicating RNA with a molecular weight of about 50,000 (refs. 1 and 2). Because there seems to be no helper virus in the system1, the RNA must rely for its replication principally on biosynthetic systems already functioning in the host.

The term “viroid” has been introduced to denote a recently recognized class of subviral plant pathogens (7). Presently known viroids consist solely of a short strand of RNA with a molecular weight of about 75,000 to 125,000 daltons. Introduction of this low-molecular-weight RNA into susceptible hosts leads to replication of the RNA and, in some hosts ...
