The zoospore ofPhlyctochytrium aestuarii
Protoplasma, 1977An ultrastructural study of the zoospore ofPhlyctochytrium aestuarii Ulken is presented. It is shown to be almost identical to the zoospore ofP. sp., isolate 71-1-E, described byKazama (1972 a and 1972 b), the only significant difference in the ultrastructure of the zoospores being a less well developed “eyespot”-like complex in the isolate studied ...

Zoosporic fungi of Oceania. VI. Species with biflagellate zoospores
Mycopathologia et Mycologia Applicata, 1969Several species of the Plasmodiophoraceae, Olpidiopsidaceae and Lagenidiaceae were isolated on various substrata from the soils of Oceania. Among these were two parasites of rotifer eggs,Lagenidium septatum andMyzocytium fijiensis. The former species is characterized primarily by septation of the thallus into segments which develop into resting spores ...

Zoospore development in the oomycetes
Fungal Biology Reviews, 2007Abstract Oomycetes cause destructive diseases on both animals and plants. The epidemic spread of oomycete diseases is primarily based on rapid dispersal from host to host by free swimming zoospores. These single-nucleated spores are formed in sporangia and are only released in aqueous environments.

Zoospores in Scenedesmus obliquus
Science, 1963In basal medium without a nitrogen source a 3-day-old culture of Scenedesmus obliquus produced zoospores, which were biflagellated, had a parietal chloroplast, lacked a pyrenoid, and were apparently not walled. Identical results were produced with new clones. A reconsideration of the relationships and classification

The zoospore ofOlpidium brassicae
Protoplasma, 1976The ultrastructure of the zoospore ofOlpidium brassicae is described and compared with observations made of other zoospores of the uniflagellatePhycomycetes. The zoospore ofO. brassicae is characterized by an extensive, cone-shaped rhizoplast and a lack of a nuclear cap, as well as a side-body complex or a rumposome.

Chemotaxis of Zoospores for Root Exudates
Science, 1961A chemotactic response of the zoospores of a soil-inhabiting plant pathogenic fungus, Phytophthora cinnamomi, for roots of avocado seedlings was observed. The chemotaxis of the zoospores and chemotropy of their germ tubes were directly related to infection and disease production.

Archiv f�r Mikrobiologie, 1968
In a further study of the zoosporic fungi of Oceania three new species of Rhizophydium, R. rarotonganensis, R. angulosum, and R. condylosum were isolated on various substrata from soil. Rhizophydium rarotonganensis is a parasite of Nowakowskiella profusa and causes marked local hypertrophy of the rhizomycelium.

Quantitative methods for the analysis of zoosporic fungi
Journal of Microbiological Methods, 2012Quantitative estimations of zoosporic fungi in the environment have historically received little attention, primarily due to methodological challenges and their complex life cycles. Conventional methods for quantitative analysis of zoosporic fungi to date have mainly relied on direct observation and baiting techniques, with subsequent fungal ...

Zoospore Ciliation in the Plasmodiophorales
Nature, 1934ZOOSPORES of Plasmodiophora brassicae, Woron. and Spongospora subterranea, (Wallroth) Lagerheim have been described in the literature as uniciliate. Examination of active zoospores would appear to substantiate this description. However, when preparations stained by Cotners1 method are used, it can be shown that in addition to the long cilium, so ...
