Entomologia Experimentalis et Applicata, Volume 171, Issue 5, Page 395-405, May 2023., 2023 Tomato chlorotic spot virus (TCSV), vectored by thrips, is an important disease of tomato in South Florida, USA. We investigated the presence of thrips and TCSV in 24 ornamental plant species. Thrips, mainly Frankliniella occidentalis and Frankliniella schultzei (Thysanoptera: Thripidae), were found in high abundance in ornamental flowering plants in a

Pest categorisation of Capsicum chlorosis virus
EFSA Journal, Volume 20, Issue 6, June 2022., 2022 Abstract The EFSA Panel on Plant Health conducted a pest categorisation of Capsicum chlorosis virus (CaCV) for the EU territory. The identity of CaCV, a member of the genus Orthotospovirus (family Tospoviridae), is established and reliable detection and identification methods are available. The pathogen is not included in the EU Commission Implementing

Molecular Plant Pathology, Volume 23, Issue 5, Page 707-719, May 2022., 2022 Tomato zonate spot virus (TZSV) NSs suppresses RNA silencing of the host plant and enhances TZSV pathogenicity through its interaction with NbSGS3. Abstract Viral suppressors of RNA silencing (VSRs) are encoded by diverse viruses to counteract the RNA silencing‐mediated defence mounted by the virus‐infected host cells.

Analysis of Tospovirus NSs Proteins in Suppression of Systemic Silencing. [PDF]
PLoS ONE, 2015 RNA silencing is a sequence-specific gene regulation mechanism that in plants also acts antiviral. In order to counteract antiviral RNA silencing, viruses have evolved RNA silencing suppressors (RSS).

Facing Rose rosette virus: A risk to European rose cultivation
Plant Pathology, Volume 69, Issue 9, Page 1603-1617, December 2020., 2020 In this review we describe current knowledge about Rose rosette virus, the molecular and serological methods available for its detection, pathways to entry, and the possible impact if it establishes and spreads in Europe. Abstract Roses (Rosa) are one of the most valuable ornamental flowering shrubs around the globe.

Groundnut Ringspot Orthotospovirus: An Emerging Problem for Soybean Production in São Paulo State
Plant Pathology, Volume 74, Issue 9, Page 2846-2856, December 2025.Groundnut ringspot orthotospovirus is widely distributed in soybean fields in São Paulo State and is transmitted by thrips and, rarely, via seeds; it is a threat to soybean production with implications for virus spread and management. ABSTRACT Orthotospoviruses affect vegetable, leguminous and ornamental plants globally and are transmitted by thrips ...
