Biased Pol II fidelity contributes to conservation of functional domains in the Potato spindle tuber viroid genome. [PDF]
PLoS Pathog, 2020 Accurate calculation of mutation rates for viruses and viroids is necessary for evolutionary studies and to evaluate adaptation potential. However, estimation of in vivo mutation rates is complicated by selection, which leads to loss or proliferation of ...

Time-Resolved Observation of the Destination of Microinjected Potato Spindle Tuber Viroid (PSTVd) in the Abaxial Leaf Epidermal Cells of Nicotiana benthamiana [PDF]
Microorganisms, 2020 Viroids are single-stranded noncoding RNA molecules of 250–400 nucleotides that cause plant diseases. One of the two families of viroids is Pospiviroidae, the members of which replicate in the nuclei of host cells.

Cellular Basis of Potato Spindle Tuber Viroid Systemic Movement
Virology, 2001 Viroids are small, nontranslatable pathogenic RNAs that replicate autonomously and traffic systemically in their host plants. We have used in situ hybridization to analyze the trafficking pattern of Potato spindle tuber viroid (PSTVd) in tomato and Nicotiana benthamiana.

The discovery and eradication of potato spindle tuber viroid in Canada. [PDF]
Virusdisease, 2014 In 1960s, potato spindle tuber was thought to be a viral disease. In 1971, the agent of the disease was characterised as a low-molecular weight infectious ribonucleic acid (RNA), which was named as 'viroid', specifically Potato spindle tuber viroid (PSTVd)).

PROCEEDINGS ON APPLIED BOTANY GENETICS AND BREEDING, 2023 Background. It is known that the pathological phenotype of potato plants can be mediated by complementary interactions between the genomic RNA of PSTVd and mRNA of some regulatory genes, which consequently lead to RNA interference, the synthesis of small

Identification and Molecular Mechanisms of Key Nucleotides Causing Attenuation in Pathogenicity of Dahlia Isolate of Potato Spindle Tuber Viroid. [PDF]
Int J Mol Sci, 2020 While the potato spindle tuber viroid (PSTVd) variant, PSTVd-Dahlia (PSTVd-D or PSTVd-Dwt) induces very mild symptoms in tomato cultivar ‘Rutgers’, PSTVd-Intermediate (PSTVd-I or PSTVd-Iwt) induces severe symptoms.

Evidence Supporting That RNA Polymerase II Catalyzes De Novo Transcription Using Potato Spindle Tuber Viroid Circular RNA Templates. [PDF]
Viruses, 2020 Transcription is a fundamental process that mediates the interplay between genetic information and phenotype. Emerging evidence indicates that RNA polymerase II (Pol II) can catalyze transcription using both DNA and RNA templates.

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.

Scion on a stock producing siRNAs of potato spindle tuber viroid (PSTVd) attenuates accumulation of the viroid. [PDF]
PLoS ONE, 2013 Plants can attenuate the replication of plant viruses and viroids by RNA silencing induced by virus and viroid infection. In higher plants, silencing signals such as small interfering RNAs (siRNAs) produced by RNA silencing can be transported ...
