Spongospora subterranea f. sp. is an important pathogen of potato responsible for major losses in most growing regions the world. Infection initiated by biflagellated motile zoospores released from long-lived resting spores. Zoospore chemotaxis to host plant root widely believed be stimulated exudate compounds, although direct evidence lacking. This study refined traditional capillary assay, with which we provided first empirical S. zoospore chemotaxis. Individual metabolites were either...
Abstract Tomato plants are highly susceptible to root infection by Spongospora subterranea and commonly used as bioassay hosts. The impacts of with S. on plant productivity yield have been debated. Recent experiments potato, the major economic host , indicated significantly reduced growth potato following heavy infection. However, there very few similar studies that examined possible tomato growth. Three cultivars, “Grape,” “Roma” “Truss,” were challenged inoculum in hydroponic culture....
Ca2+ signaling regulates physiological processes including chemotaxis in eukaryotes and prokaryotes. Its inhibition has formed the basis for control of human disease but remains largely unexplored plant disease. This study investigated role on motility Spongospora subterranea zoospores, responsible root infections leading to potato tuber Cytosolic flux with antagonists were found alter zoospore swimming patterns constrain chemotaxis, attachment zoosporangia infection. LaCl3 GdCl3, both...
In spite of the huge economic importance Aframomum melegueta in herbal and pharmaceutical industries, its production is limited by lack planting materials (propagules). The plant also lacks scientific descriptors, which has often led to misidentification with adverse health implications. We therefore aimed at developing a descriptor list facilitate identification A. using 34 morphometric traits comprising 18 quantitative 16 qualitative characters. morphological showed that characteristic...
Groundnut (Arachis hypogaea L.) production is threatened by the advent of many emerging pests and diseases, key among them being ringspot virus (GRSV). The numerous alternative host crops make its control particularly difficult, resulting in heightened transmission risk increased yield loss. mechanisms underlying loss, though not fully understood, have often been speculated to be a result reduction photosynthesis transpiration infected leaves. This study was therefore aimed at testing effect...
Abstract Spongospora subterranea , which causes powdery scab of potato, infects a diverse range plant species. Crop rotation as management tool will be compromised if pathogen hosts exist between potato crops. Opium poppy ( Papaver somniferum ) and pyrethrum Tanacetum cinerariifolium are important crops within intensive vegetable production rotations in NW Tasmania. Measurements S. soil inoculum commercial field showed amounts were substantially elevated following an opium crop, suggested...
