Metabolomic Fingerprinting of Potato Cultivars Differing in Susceptibility to Spongospora subterranea f. sp. subterranea Root Infection. [PDF]

Int J Mol Sci, 2020
Plants defend themselves from pathogens by producing bioactive defense chemicals. The biochemical mechanisms relating to quantitative resistance of potato to root infection by Spongospora subterranea f. sp. subterranea (Sss) are, however, not understood, and are not efficiently utilized in potato breeding programs.

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 ...

Development and validation of a novel rapid in vitro assay for determining resistance of potato cultivars to root attachment by Spongospora subterranea zoospores

Plant Pathology, 2023
We developed a novel rapid and robust in vitro assay for screening potato varietal resistance to Spongospora subterranea root attachment and infection. Abstract Spongospora subterranea f. sp. subterranea is a major pathogen of potatoes leading to losses in tuber quality and yield.

Dynamic transcriptomic responses reveal candidate defense genes against Spongospora subterranea f. sp. subterranea and Potato mop-top virus infection [PDF]

Frontiers in Plant Science
Powdery scab, caused by Spongospora subterranea f.sp. subterranea (Sss), is persistent soilborne disease of potato. Sss is also a vector for Potato mop-top virus (PMTV), posing another significant threat to tuber quality and marketability.
