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.

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 ...

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.

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.

European Journal of Plant Pathology, 1999
PCR-based methods were developed for the detection and quantification of the potato pathogen Spongospora subterranea f. sp. subterranea (S. subterranea) in peel, tuber washings and soil. A partial sequence was obtained for S. subterranea ribosomal DNA and specific PCR primers (Sps1 and Sps2) were chosen from the internal transcribed spacer regions ...

The stages of the sporangiogenous phase in the life-cycle of S. subterranea t. sp. nasturtii were observed using transmission electron microscopy. The vegetative multinucleate plasmodium and its association with the host cytoplasm is described. Uninucleate zoosporangia are produced at the onset of sporogenesis when cleavage vacuoles coalesce to form ...

The early stages (up to 72 h) of the infection cycle of Spongospora subterranea f. sp. nasturtii were investigated. Within 48 h, zoospores encysted on roots and produced adhesoria, the cyst wall which formed during zoospore encystment underwent changes in morphology. Cysts contained a dense-staining bullet-like stachel which may be involved in host

Variabilidad genética de Spongospora subterranea f. sp. subterranea en Colombia
2012Powdery scab (Spongospora subterranea f. sp. subterranea - Sss) is one of the most important re-emerging diseases of potato crops in Colombia. Sss can cause severe root damage and compromise the quality of tubers. Moreover, Sss zoospores can also serve as vector of Potato mop-top virus (PMTV, Pomovirus).
