Revised Taxonomy and Expanded Biodiversity of the Phytomyxea (Rhizaria, Endomyxa)

Journal of Eukaryotic Microbiology, Volume 67, Issue 6, Page 648-659, November/December 2020., 2020
Abstract Phytomyxea (phytomyxids) is a group of obligate biotrophic pathogens belonging to the Rhizaria. Some phytomyxids are well studied and include known plant pathogens such as Plasmodiophora brassicae, the causal agent of clubroot disease. Despite this economic importance, the taxonomy and biodiversity of this group are largely cryptic, with many ...

List of non‐EU viruses and viroids infecting potato (Solanum tuberosum) and other tuber‐forming Solanum species

EFSA Journal, Volume 18, Issue 1, January 2020., 2020
Abstract The European Commission requested a pest categorisation of the non‐EU viruses and viroids of potato (hereafter referred to as viruses). As a first step, a systematic literature and database search was carried out to identify the viruses reported to naturally infect Solanum tuberosum and other tuber‐forming Solanum spp (hereafter referred to as

Pest categorisation of non‐EU viruses and viroids of potato

EFSA Journal, Volume 18, Issue 1, January 2020., 2020
Abstract Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of those viruses and viroids (hereafter referred to as viruses) of Solanum tuberosum and other tuber‐forming Solanum spp. (hereafter referred to as potato) which are considered to be either non‐EU or of undetermined standing based on a ...

Detection of RNA viruses in potato seed-tubers from northern Antioquia (Colombia)

Revista Ceres, 2023
The most important viruses infecting potato in Colombia are PVY, PLRV, PVS, PYVV, PVV, PVX, PMTV, and PVB. Unfortunately, recent investigations on the health status of uncertified and certified seed-tubers of Solanum tuberosum cv.

Transformation of Nicotiana benthamiana with the Potato Mop-Top Virus Coat Protein Gene Produces a Novel Resistance Phenotype Mediated by the Coat Protein

Molecular Plant-Microbe Interactions, 1998
Transformed lines of Nicotiana benthamiana expressing a translatable transgene (CPtrans) encoding the coat protein (CP) gene of potato mop-top virus (PMTV) differed considerably in steady-state levels of transgene RNA transcript and CP that were ...

Comparative Transcriptome Profiling of Nicotiana benthamiana Plants Infected with Potato Mop-Top Virus and Its Mutant Lacking a Gene for the 8K Protein Underlines the Role of Chloroplasts During Infection

Molecular Plant-Microbe Interactions
Potato mop-top virus (PMTV) is a significant pathogen causing potato “spraing” disease worldwide. The PMTV 8K protein functions as a weak viral suppressor of RNA silencing (VSR), has viroporin activity, and plays a role in pathogenicity by promoting ...

Potato mop-top virus RNA Can Move Long Distance in the Absence of Coat Protein: Evidence from Resistant, Transgenic Plants

Molecular Plant-Microbe Interactions, 2000
Transgenic expression of a translatable version of the Potato mop-top virus (PMTV) coat protein (CP) gene (encoded by RNA 3) in Nicotiana benthamiana prevented production of symptoms and infective virus particles.

Unusual Features of Pomoviral RNA Movement

Frontiers in Microbiology, 2011
Potato mop-top pomovirus (PMTV) is one of a few viruses that can move systemically in plants in the absence of the coat protein (CP). Pomoviruses encode the triple gene block genetic module of movement proteins (TGB 1, 2 & 3) and recent research ...

Recent Advances in Biology, Epidemiology and Host Resistance to Potato Powdery Scab

Plant Pathology, Volume 75, Issue 3, May–June 2026.
This review highlights recent advances in understanding powdery scab and potato resistance, providing new perspectives for developing durable and integrated strategies to manage the disease. ABSTRACT Powdery scab of potatoes (Solanum tuberosum) is caused by the soil‐borne protist Spongospora subterranea f. sp. subterranea (Sss).
