Synthesis of DNA transcripts of potato spindle tuber viroid [PDF]

FEBS Letters, 1977
1. Introduction Sequences in the DNA of several uninfected solanaceous host species have recently been shown to represent at least 60% of potato spindle tuber viroid (PSTV) [ l] . PSTV replication is known to be inhibited by actinomycin D, which suggests involve- ment of DNA [2,3].

PSTVd infection in Nicotiana benthamiana plants has a minor yet detectable effect on CG methylation

Frontiers in Plant Science, 2023
Viroids are small circular RNAs infecting a wide range of plants. They do not code for any protein or peptide and therefore rely on their structure for their biological cycle.

Development of a PCR-test system for detection of the Potato spindle tuber viroid

Proceedings of the Komi Science Centre of the Ural Division of the Russian Academy of Sciences, 2022
The Potato spindle tuber viroid infects potato plants, causing a serious damage to agriculture by reducing yields. Therefore, there is a need to identify this pathogen.

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

Incidence of potato virus diseases and their significance for a seed certification program in Lebanon

Phytopathologia Mediterranea, 2001
Potato fields in the two main production areas of Lebanon, the Bekaa and Akkar plains, were surveyed in two growing seasons for viruses and other pathogens of significance for a potato seed certification program.

Epidemiological Insights Into Water and Soil‐Mediated Transmission of Tomato Mottle Mosaic Virus

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Water and growing substrate can serve as reservoirs for tomato mottle mosaic virus (ToMMV) inoculum. ToMMV can survive in water for up to 27 weeks. ToMMV infects bait plants through roots within 5–17 weeks, depending on the severity of root damage. A rapid, field‐deployable RPA test—requiring no RNA extraction—offers sensitivity comparable to RT‐qPCR ...

Predicting symptom severity in PSTVd-infected tomato plants using the PSTVd genome sequence. [PDF]

Mol Plant Pathol
The severity of symptoms induced by viroids in host plants can be predicted from genome sequences using unsupervised machine‐learning algorithms without the need for biological experiments. Abstract Viroids, one of the smallest known infectious agents, induce symptoms of varying severity, ranging from latent to severe, based on the combination of ...

Reassessment of Viroid RNA Cytosine Methylation Status at the Single Nucleotide Level

Viruses, 2019
Composed of a few hundreds of nucleotides, viroids are infectious, circular, non-protein coding RNAs able to usurp plant cellular enzymes and molecular machineries to replicate and move in their hosts. Several secondary and tertiary RNA structural motifs

Sequence homology between potato spindle tuber viroid and U3B snRNA [PDF]

FEBS Letters, 1983
Sequence homology was found by computer analysis between potato spindle tuber viroid (PSTV) RNA and U3B snRNA of Novikoff hepatoma cells. This homology is colinear in arrangement, extends in length to 81% of the entire U3B snRNA molecule and is involved in the PSTV molecule unique sites which, if depicted in terms of the secondary structure of the ...
