Infection of potato by Spongospora subterranea
Mycological Research, 1991Evidence that potato tubers are susceptible to infection by Spongospora subterranea only during lenticel formation and proliferation is presented and the capacity of apparently healthy tubers to carry low levels of inoculum is demonstrated. The significance to infection of the histological changes during the transformations of stomata to lenticels is

Alternative hosts of Spongospora subterranea f. sp. subterranea in southern Africa
European Journal of Plant Pathology, 2020Spongospora subterranea f. sp. subterranea (Sss) is an obligate parasite that can only multiply within the living tissues of a host plant. Greenhouse experiments were carried out to determine the host status of Sss in some crops and weeds commonly found in southern African fields.

Serological Detection of Spongospora Subterranea F.SP. Subterranea in Soil
1997A bioassay with tomato as bait plants was compared with detection by ELISA using a dilution series of spore balls in uncontaminated soil. The relationship between A405 values and spore ball concentration/g soil appeared to be linear and raw antiserum detected down to 100 spore balls/g soil.

Potato powdery scab caused by Spongospora subterranea subsp . subterranea (Sss) causes extensive damage to the quality and marketability of tubers. Disease outbreaks in potatoes grown in virgin soils in south Israel, lead us to the hypothesis that wind-driven inoculum may also be a source of new infections.

Ultrastructural karyology of Spongospora subterranea (Plasmodiophoromycetes)
Canadian Journal of Botany, 1992Sporogenic (cystogenous) stages of development of Spongospora subterranea (Wallroth) Lagerheim f.sp. subterranea Tomlinson infecting potato tubers were examined with transmission electron microscopy. Volume of nuclei in transitional Plasmodia was 28.2 ± 8.3 μm3.

A polyclonal antiserum has been produced against spore balls of Spongospora subterranea f.sp. subterranea prepared from potato tubers. It was able to detect as little as 0.02 spore balls in enzyme-linked immunosorbent assay (ELISA). It detected spore balls of different cultivar origin equally well.

The plasmodiophorid pathogen Spongospora subterranea f. sp. subterranea causes powdery scab disease of potatoes (Solanum tuberosum L.), which severely affects tuber quality. Adequate chemical control of the disease is lacking, so breeding resistant potato cultivars is important.

A technique for detection of Spongospora subterranea in soil
Transactions of the British Mycological Society, 1983A simple and rapid technique using tomato seedlings as baits has been developed to detect Spongospora subterranea in soils. Seedling roots were microscopically examined for the presence of sporangia. A sensitivity test showed that the technique can detect at least 10 spore balls/150 ml solution.
