Effects of Different Soil Treatments on the Development of Spongospora subterranea f. sp. subterranea in Potato Roots and Tubers in the Greenhouse [PDF]

Potato Research, 2017
Powdery scab caused by Spongospora subterranea f. sp. subterranea (Sss) causes extensive losses in potato production systems globally. Two pot experiments were established in the greenhouse in summer 2013 and winter 2014 to evaluate the effectiveness of different soil chemicals, fumigant, amendments and biological control agents (BCAs) against Sss in ...

Pest categorisation of Synchytrium endobioticum

EFSA Journal, Volume 16, Issue 7, July 2018., 2018
Abstract The Panel on Plant Health performed a pest categorisation of the fungus Synchytrium endobioticum, the causal agent of potato wart disease, for the European Union (EU). The identity of the pest is well established and reliable methods exist for its detection and identification. S. endobioticum is present in most continents.

Long‐Read Metabarcoding With Optimized Bioinformatic Analysis Outperforms Short‐Read Metabarcoding for Assessing Soil Protist Diversity and Ecology

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Comparing 18S metabarcoding of protist cultures and environmental samples with short and long read sequencing highlighted the advantages of each method. In particular, the study of 26 vineyard soil samples with long reads showed high potential and reliability for ecological research with an increased sensitivity to environmental patterns.

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).

Single Cystosorus Isolate Production and Restriction Fragment Length Polymorphism Characterization of the Obligate Biotroph Spongospora subterranea f. sp. subterranea [PDF]

Phytopathology®, 2006
Spongospora subterranea f. sp. subterranea causes powdery scab in potatoes and is distributed worldwide. Genetic studies of this pathogen have been hampered due, in part, to its obligate parasitism and the lack of molecular markers for this pathogen.

First Report of Marinomyxa spp. (Rhizaria: Endomyxa: Phytomyxea) Infection in Seagrasses Halophila beccarii and Halophila decipiens: Supporting Evidence for a Long‐Standing Symbiosis

Plant Pathology, Volume 75, Issue 3, May–June 2026.
A survey of phytomyxid parasites in seagrasses of the genus Halophila reveals previously unrecognised diversity and a widespread presence of Marinomyxa within Halophila meadows, supporting a tight co‐evolutionary relationship between the two genera. ABSTRACT Marinomyxa is a genus of obligate intracellular parasitic protists known to infect tropical ...

First Confirmed Report of Powdery Scab Caused by Spongospora subterranea f. sp. subterranea on Potato in Sri Lanka

Plant Disease, 2011
White, wart-like outgrowths on roots and stolons – root galls – and blisters and pustules on tubers (lesions) are characteristic symptoms of the potato powdery scab disease caused by Spongospora subterranea (Wallr.) f. sp. subterranea. In Sri Lanka, potato is a major cash crop primarily in two agroecological zones of higher altitude, Nuwara Eliya and ...

First Report of Potato Powdery Scab, Caused by Spongospora subterranea f. sp. subterranea, in North Dakota

Plant Disease, 1997
Powdery scab is a serious disease of potatoes (Solanum tuberosum L.) that can cause extensive surface defects on susceptible potato cultivars. The pathogen, Spongospora subterranea (Wallr.) Lagerh. f. sp. subterranea J. A. Tomlinson, is an important concern in seed potato production because current seed certification standards in North Dakota have a ...
