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 ...

Mycological Research, 1996
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

Plant Disease
Spongospora subterranea f. sp. subterranea (Sss) is a soilborne potato pathogen responsible for causing powdery scab on tubers and galls on roots, reducing root water uptake through colonizing root hairs, and vectoring of Potato mop-top virus (PMTV).

Ninety-nine potato (Solanum tuberosum) cultivars and 13 breeding lines were assessed in field trials for susceptibility to powdery scab (caused by Spongospora subterranea f. sp. subterranea). The trials wer e carried out over 11 growing seasons (each cultivar/line tested in at least two growing seasons) in soil inoculated with S.
