Molecular data reallocates Sorosphaerula radicalis (Plasmodiophorida, Phytomyxea, Rhizaria) to the genus Hillenburgia. [PDF]

J Eukaryot Microbiol, 2022
Abstract This study reports the first record of Sorosphaerula radicalis (Phytomyxea, Rhizaria) in continental Europe (Tirol, Austria) and provides first molecular data for this species. An 18S rRNA phylogeny placed S. radicalis into the Plasmodiophorida, although distant from other members of the genus Sorosphaerula and close to the parasite of water ...

Phagocytosis underpins the biotrophic lifestyle of intracellular parasites in the class Phytomyxea (Rhizaria). [PDF]

New Phytol, 2023
Summary Phytomyxea are intracellular biotrophic parasites infecting plants and stramenopiles, including the agriculturally impactful Plasmodiophora brassicae and the brown seaweed pathogen Maullinia ectocarpii. They belong to the clade Rhizaria, where phagotrophy is the main mode of nutrition.

Revised Taxonomy and Expanded Biodiversity of the Phytomyxea (Rhizaria, Endomyxa). [PDF]

J Eukaryot Microbiol, 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 ...

Pest categorisation of non-EU viruses and viroids of potato. [PDF]

EFSA J, 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 ...

Pest categorisation of Thecaphora solani. [PDF]

EFSA J, 2018
Abstract The Panel on Plant Health performed a pest categorisation of the fungus Thecaphora solani, the causal agent of smut of potato, for the EU. The identity of the pest is well established and reliable methods exist for its detection and identification. T.

Foliar treatments of 2,4-dichlorophenoxyacetic acid for control of common scab in potato have beneficial effects on powdery scab control. [PDF]

ScientificWorldJournal, 2014
Prior studies have shown that applications of the synthetic auxin 2,4‐dichlorophenoxyacetic acid (2,4‐D) to the foliage of potato plants can reduce common scab. Here field and glasshouse trials suggest that 2,4‐D foliar treatments may also reduce the biologically distinct tuber disease, powdery scab.
