Light is a crucial signal for zoosporogenesis and gametogenesis in some green microalgae
European Journal of Phycology, 2013 Patterns of reproduction were investigated in some microalgal species of Chlorophyceae (Botryosphaerella sudetica, Neochloris aquatica, Neochloris vigensis, Bracteacoccus minor). Under continuous light, the microalgae reproduced asexually producing autospores.

European Journal of Protistology, 1989 The fine structure of mitosis and cytokinesis leading to formation of zoospores in the unicellular tribophycean alga Botrydiopsis alpina Vischer has been studied by ultra-rapid cryofixation, freeze substitution, and electron microscopy. Preceding zoosporogenesis, the cell usually enlarges considerably and becomes multinucleate.

Microtubule organization during zoosporogenesis inAllomyces macrogynus
Protoplasma, 1997 The microtubule cytoskeleton and cytoplasmic organization ofAllomyces macrogynus during zoosporogenesis was studied using light and electron microscopy. Indirect immunofluorescence methods revealed that the microtubule cytoskeleton progressed through three distinct stages of cytoplasmic distribution during zoospore development.

Ultrastructure of Zoosporogenesis in Allomyces macrogynus [PDF]
Journal of General Microbiology, 1974 The formation of zoospores in the aquatic Phycomycete, Allomyces macrogynus, has been studied with the electron microscope. Flagellum formation, zoospore-membrane formation and nuclear-cap formation comprise the sequence of major events that occur within a zoosporangium upon the addition of water to a culture of the organism growing on an agar surface.

An ultrastructural study of zoosporogenesis inPythium proliferum de Bary
Protoplasma, 1976 Zoosporogenesis in the oomycete,Pythium proliferum de Bary initially involves a condensation of cytoplasm at certain hyphal tips and the subsequent enlargement of these hyphal tips to form sporangia. Deposition of a septum at the base of the sporangium and initiation of an apical papilla are followed by cleavage of the sporangial cytoplasm.

The Morphology of Lagenidium Callinectes II. Zoosporogenesis
Mycologia, 1974 Zoosporogenesis in the holocarpic marine phycomycete Lagenidium callinectes is initiated when actively growing mycelium is washed free of medium and placed in sea water.

Changes in intracellular pH during zoosporogenesis inPhytophthora cinnamomi
Protoplasma, 1996 Changes in intracellular pH (pHi) have been examined during zoosporogenesis inPhytophthora cinnamomi in order to elucidate the molecular mechanisms that bring about initiation of the orderly cleavage of the sporangium. By microinjecting a dextranconjugated pH-sensitive fluorescent indicator, 2′,7′-bis(2-carboxyethyl)-5(6)-carboxyfluorescein (BCECF ...

Multiple Pathways Regulate the Induction of Genes During Zoosporogenesis in Phytophthora infestans [PDF]
Molecular Plant-Microbe Interactions®, 2004 Zoospores are a critical component of the disease cycles of most oomycete pathogens. To better understand this stage, genes induced during zoosporogenesis were identified from Phytophthora infestans, the potato late blight pathogen. Using cDNA arrays representing 2,600 genes expressed during zoosporogenesis, 69 genes showing >fourfold increases in ...
