TOR Inhibition Enhances Autophagic Flux and Immune Response in Tomato Plants Against PSTVd Infection

Physiologia Plantarum, Volume 176, Issue 6, November/December 2024.
Abstract 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

Viroid-infected Tomato and Capsicum Seed Shipments to Australia

Viruses, 2019
Pospiviroid species are transmitted through capsicum and tomato seeds. Trade in these seeds represents a route for the viroids to invade new regions, but the magnitude of this hazard has not been adequately investigated. Since 2012, tomato seed lots sent

The spread of new viral pathogens and phytoplasmas in cultivated plants and their risks

Food Risk Assess Europe, Volume 4, Issue 1, January 2026.
Abstract The study contains a description of the genome and particles, spectrum of host plants, geographical distribution, forecast of spread and impacts on agricultural production, disease symptoms, life cycle, and means of protection in integrated and organic production in the Czech Republic for 22 plant viruses, 3 viroids and 4 phytoplasmas, in ...

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Costa Rica

EFSA Journal, Volume 22, Issue 11, November 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Costa Rica.

Detection of tomato brown rugose fruit virus in environmental residues: The importance of contextualizing test results

Plant Pathology, Volume 73, Issue 8, Page 2071-2083, October 2024.
ToBRFV or its residues were detected on nonhost plants and surfaces in and around greenhouses; more often in areas with nearby tomato production but also in a wider environment beyond infected crops. Abstract Tomato brown rugose fruit virus (ToBRFV) is regulated as a quarantine pest in many countries worldwide.

Potato spindle tuber viroid Strains of Different Pathogenicity Induces and Suppresses Expression of Common and Unique Genes in Infected Tomato

Molecular Plant-Microbe Interactions, 2002
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.

RNA Structural Features Responsible for Potato Spindle Tuber Viroid Pathogenicity

Virology, 1996
The native structure of potato spindle tuber viroid (PSTVd) contains a series of short double helices and small internal loops that are organized into five structural domains. Nucleotides within the pathogenicity domain are known to play a critical role in modulating PSTVd symptom expression, and it has been suggested that disruption of a comparatively

Global Analysis of Tomato Gene Expression During Potato spindle tuber viroid Infection Reveals a Complex Array of Changes Affecting Hormone Signaling

Molecular Plant-Microbe Interactions, 2012
Viroids like Potato spindle tuber viroid (PSTVd) are the smallest known agents of infectious disease—small, highly structured, circular RNA molecules that lack detectable messenger RNA activity, yet are able to replicate autonomously in susceptible plant

Interdependence of Pathogenicity and Replicability with Potato Spindle Tuber Viroid

Virology, 1995
After the unexpected appearance of lethal symptoms on tomato plants infected with the PSTVd strain Intermediate Di, viroids were isolated and sequenced. It was found that a new strain, named RG 1, had been generated spontaneously in our greenhouse.
