Alternative hosts of Spongospora subterranea f. sp. subterranea in southern Africa [PDF]
European Journal of Plant Pathology, 2020 Spongospora 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.

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
