Viroids are the smallest plant pathogens. These RNAs do not encode proteins and are not encapsidated, and yet they can replicate autonomously, move systemically, and cause diseases in infected plants.

Viroids, the simplest RNA replicons: How they manipulate their hosts for being propagated and how their hosts react for containing the infection [PDF]
[EN] The discovery of viroids about 45 years ago heralded a revolution in Biology: small RNAs comprising around 350 nt were found to be able to replicate autonomously and to incite diseases in certain plants without encoding proteins, fundamental ...

In order to analyze the production of small RNA (sRNA) by viroids upon infecting the plants, the tomato plants (Solanum lycopersicum cultivar Rutgers) were inoculated with the variants of Potato spindle tuber viroid (PSTVd).

Viroid-derived small RNA induces early flowering in tomato plants by RNA silencing [PDF]
: Viroid infection often leads to early flowering in the host plant. This report describes the targeting of the FRIGIDA-like protein 3 (FRL3) mRNA in tomato plants by a small RNA derived from the conserved left terminal region of the potato spindle tuber

Molecular basis of viroid RNA-templated transcription [PDF]
Transcription is a fundamental process catalyzed by DNA-dependent RNA polymerases (DdRPs). Interestingly, some DdRPs can use both DNA and RNA as templates for transcription.

Characterization of a Tomato Protein Kinase Gene Induced by Infection by Potato spindle tuber viroid
Viroids—covalently closed, circular RNA molecules in the size range of 250 to 450 nucleotides—are the smallest known infectious agents and cause a number of diseases of crop plants.

It is well established that viroid derived small RNA (vd-sRNA) induces RNA silencing of endogenous mRNA. However, it remains not clear how exactly viroid infections can lead to severe symptom induction given the fact that fewer vd-sRNAs binding the ...

To date, two plant genes encoding RNA-dependent RNA polymerases (RdRs) that play major roles in the defense against RNA viruses have been identified: (i) RdR1, which is responsible for the viral small RNAs (vsRNAs) found in virus-infected plants, and ...

Allelic RNA Motifs in Regulating Systemic Trafficking of Potato Spindle Tuber Viroid
Intercellular RNA trafficking has been shown as a widely-existing phenomenon that has significant functions in many aspects of biology. Viroids, circular noncoding RNAs that cause plant diseases, have been a model to dissect the role of RNA structural ...

Citrus exocortis viroid causes ribosomal stress in tomato plants [PDF]
[EN] Viroids are naked RNAs that do not code for any known protein and yet are able to infect plants causing severe diseases. Because of their RNA nature, many studies have focused on the involvement of viroids in RNA-mediated gene silencing as being ...
