Viroids: From Genotype to Phenotype Just Relying on RNA Sequence and Structural Motifs [PDF]

, 2017
As a consequence of two unique physical properties, small size and circularity, viroid RNAs do not code for proteins and thus depend on RNA sequence/structural motifs for interacting with host proteins that mediate their invasion, replication, spread ...

Rolling-circle replication of viroids, viroid-like satellite RNAs and hepatitis delta virus: variations on a theme [PDF]

, 1999
Viroids and viroid-like satellite RNAs from plants, and the human hepatitis delta virus (HDV) RNA share some properties that include small size, circularity and replication through a rolling-circle mechanism.

Root Transcriptomic Analysis Reveals Global Changes Induced by Systemic Infection of Solanum lycopersicum with Mild and Severe Variants of Potato Spindle Tuber Viroid

Viruses, 2019
Potato spindle tuber viroid (PSTVd) causes systemic infection in plant hosts. There are many studies on viroid-host plant interactions, but they have predominantly focused on the aboveground part of the plant. Here, we investigated transcriptomic profile

Silencing of transcription factor encoding gene StTCP23 by small RNAs derived from the virulence modulating region of potato spindle tuber viroid is associated with symptom development in potato.

PLoS Pathogens, 2019
Viroids are small, non-protein-coding RNAs which can induce disease symptoms in a variety of plant species. Potato (Solanum tuberosum L.) is the natural host of Potato spindle tuber viroid (PSTVd) where infection results in stunting, distortion of leaves

Detektion des Kartoffelspindelknollen Viroids mit Hilfe der Loop Mediated Isothermal Amplification [PDF]

, 2011
PSTV ist ein hoch infektiöses Viroid, das in Kartoffeln verkleinerte und spindelähnliche Knollen verursacht. Um Ernteverlusten vorzubeugen, ist eine Detektion in frühen Infektionsstadien von großer Bedeutung.

Conformational stability of loop E in the Potato Spindle Tuber Viroid (PSTVd)

The FASEB Journal, 2013
Viroids are small autonomously replicating plant pathogens consisting of non‐encapsidated, circular, single‐stranded RNA. Viroid RNA does not code for proteins; therefore their primary function is to interact with host proteins or other RNAs to carry out replication and pathogenesis.

RNAi-Mediated Down-Regulation of Dicer-Like 2 and 4 Changes the Response of ‘Moneymaker’ Tomato to Potato Spindle Tuber Viroid Infection from Tolerance to Lethal Systemic Necrosis, Accompanied by Up-Regulation of miR398, 398a-3p and Production of Excessive Amount of Reactive Oxygen Species

Viruses, 2019
To examine the role of RNA silencing in plant defenses against viroids, a Dicer-like 2 and 4 (DCL2&4)–double knockdown transgenic tomato plant line, 72E, was created.

Potato spindle tuber viroid as Inducer of RNA Silencing in Infected Tomato

Molecular Plant-Microbe Interactions, 2001
Potato spindle tuber viroid (PSTVd), an RNA plant pathogen encoding no known proteins, induces systemic symptoms on tomato plants. We report detection of small RNAs of approximately 25 nucleotides with sequence specificity to PSTVd in infected plants: an

Application of RNA silencing to plant disease resistance [PDF]

, 2012
To reduce the losses caused by plant pathogens, plant biologists have adopted numerous methods to engineer resistant plants. Among them, RNA silencing-based resistance has been a powerful tool that has been used to engineer resistant crops during the ...

Insights Into Potato Spindle Tuber Viroid Quasi-Species From Infection to Disease

Frontiers in Microbiology, 2020
Viroids are non-coding RNA plant pathogens that are characterized by their possession of a high mutation level. Although the sequence heterogeneity in viroid infected plants is well understood, shifts in viroid population dynamics due to mutations over ...
