Electron microscopy of zoosporogenesis in the marine phycomycete, Lagenidium callinectes Couch
Archiv f�r Mikrobiologie, 19731. Zoosporogenesis and zoospore structure of Lagenidium callinectes, parasitic on ova of the blue crab, Callinectes sapidus, are studied by electron microscopy. 2. The cytoplasmic thread connecting discharging cytoplasmic units appears as a simple constricted area of cytoplasm, containing much membranous material, and bound by only the ...

The ultrastructure of mitosis during zoosporogenesis in Rhizidiomyces apophysatus
Canadian Journal of Botany, 1989Mitotic divisions in reproductive thalli of Rhizidiomyces apophysatus, a monocentric, eucarpic hyphochytrid, were examined ultrastructurally. Mitosis is centric; each spindle pole contains two centrioles of unequal length that lie at a 108° angle relative to each other.

Some observations on zoosporogenesis in the female strain of Oedogonium cardiacum
Canadian Journal of Botany, 1968Developmental cytological events in zoosporogenesis in Oedogonium have been studied in material stained with dilute solutions of acridine orange. Induction leads to isolation of successive protoplasts within the filament. Profound intracellular changes leading to zoospore formation are described and are considered to be the result of cellular ...

Synthesis and assembly of flagellar surface antigens during zoosporogenesis inPhytophthora cinnamomi
Protoplasma, 1994Cryomicrotomy and immunofluorescence microscopy employing three different categories of monoclonal antibody (MAb) that label antigens on the surface of one or both flagella ofPhytophthora dnnamomi have been used to follow the synthesis and assembly of flagellar surface components.

Based on transmission electron microscopy observation, zoosporogenesis in the siphonous multinucleate green alga Derbesia tenuissima can be divided into five stages. In vegetative sporophytes and Stage 1 sporangia, the cytoplasm was distinguished as two regions, the inner region of chloroplasts and the outer region of nuclei.

Cleavage membrane development and cytokinesis were examined in zoosporangia of Allomyces macrogynus treated with cytoskeletal inhibitors and compared to zoosporogenesis under control conditions. Developing membranes were visualized in living zoosporangia with laser-scanning confocal microscopy using the lipophilic membrane dye FM4-64.

Abstract C. confervae is a eucarpic, monocentric chytrid that has been cultured synchronously ( L. P. Gauriloff and M. S. Fuller, 1979 , Exp. Mycol. 3 : 3–5). In this study we use light and electron microscopy to examine the development of zoospores and the discharge apparatus, focusing on the multiple roles of the Golgi apparatus.

The organization of filamentous actin (F-actin) in living cells of the oomycete Phytophthora cinnamomi was determined during zoosporogenesis and zoospore encystment by microinjecting sporangia with fluorescently labeled phalloidin and observing resultant fluorescence by confocal microscopy. In multinucleate sporangia prior to the induction of cleavage,

The sequence of intracellular transitions leading to the formation of γ particles during zoosporogenesis was examined by electron microscopy of synchronous cultures of Allomyces macrogynus and semisynchronous cultures of Catenaria anguillulae . In Allomyces the first identifiable progenitors of the γ matrix are 60-nm-diameter electron-opaque ...
