Xanthohumol and echinocystic acid induces PSTVd tolerance in tomato [PDF]
Plant DirectTomato is a popular vegetable worldwide; its production is highly threatened by infection with the potato spindle tuber viroid (PSTVd). We obtained the full‐length genome sequence of previously conserved PSTVd and inoculated it on four genotypes of semi ...

Chloroplast clustering around the nucleus induced by OMP24 overexpression unexpectedly promoted PSTVd infection in Nicotiana benthamiana. [PDF]
Mol Plant Pathol, 2023 Overexpression of outer membrane protein 24 in Nicotiana benthamiana induces chloroplast clustering around the nucleus to enhance potato spindle tuber viroid infection. Abstract Chloroplast clustering around the nucleus is a well‐known mechanism that occurs in response to various biotic and abiotic stresses and is believed to be a mechanism of defence ...

TOR Inhibition Enhances Autophagic Flux and Immune Response in Tomato Plants Against PSTVd Infection. [PDF]
Physiol PlantAbstract Viroids are small, non‐coding RNA pathogens known for their ability to cause severe plant diseases. Despite their simple structure, viroids like Potato Spindle Tuber Viroid (PSTVd) can interfere with plant cellular processes, including transcriptional and post‐transcriptional mechanisms, impacting plant growth and yield. In this study, we have

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

PSTVd infection in Nicotiana benthamiana plants has a minor yet detectable effect on CG methylation [PDF]
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.

Three Cycles of Continuous Propagation of a Severe PSTVd Strain NicTr-3 in Solanum lycopersicum cv. Rutgers Resulted in Its Attenuation and Very Mild Disease Symptoms in Potato [PDF]
Agronomy, 2023 Potato spindle tuber viroid (PSTVd) is a small infectious non-coding circular RNA causing diseases of important crops, including tomato and potato. The symptoms vary from mild to severe depending on the viroid strain, the host plant variety, and the ...

The Secondary Structure of Potato Spindle Tuber Viroid Determines Its Infectivity in Nicotiana benthamiana [PDF]
Viruses, 2023 The function of RNAs is determined by their structure. However, studying the relationship between RNA structure and function often requires altering RNA sequences to modify the structures, which leads to the neglect of the importance of RNA sequences ...

DNA Ligase I Circularises Potato Spindle Tuber Viroid RNA in a Biomolecular Condensate. [PDF]
Mol Plant PatholWe developed a new protocol for colocalising RNA and protein and illustrated that circularisation of potato spindle tuber viroid catalysed by host DNA ligase I occurs in a biomolecular condensate proximal to the nucleolus. ABSTRACT Viroids are single‐stranded circular noncoding RNAs that mainly infect crops.

Resistance of the CRISPR-Cas13a Gene-Editing System to Potato Spindle Tuber Viroid Infection in Tomato and Nicotiana benthamiana [PDF]
VirusesGene-editing technology, specifically the CRISPR-Cas13a system, has shown promise in breeding plants resistant to RNA viruses. This system targets RNA and, theoretically, can also combat RNA-based viroids.

Transmission of potato spindle tuber viroid between Phytophthora infestans and host plants [PDF]
Вавиловский журнал генетики и селекции, 2022 Potato spindle tuber viroid (PSTVd) is a naked, circular, single-stranded RNA (356–363 nucleotides in length) which lacks any protein-coding sequences.
