Ecological functions of zoosporic hyperparasites
Frontiers in Microbiology, 2014 Zoosporic parasites have received increased attention during the last years, but it is still largely unnoted that these parasites can themselves be infected by hyperparasites.

The Zoospore of Allomyces [PDF]
Journal of General Microbiology, 1971 SUMMARY: The arrangement of cellular organelles within the zoospores of Allomyces macrogynus and A. neo-moniliformis was found to be very similar to that observed in the zoospores of Monoblepharella (Monoblepharidales). Principal among these differences are the presence in Allomyces of a distinct nuclear cap, a set of 27 microtubules, a nucleus ...

Aggregation of Phytophthora capsici Zoospores and their Interaction with Zoospores of P. palmivora [PDF]
Journal of General Microbiology, 1974 Zoospores of Phytophthora palmivora Butler aggregated without encysting within 2 min when they were suspended in water (Ko & Chase, 1973). Such zoospore behaviour was temperature-dependent with an optimum temperature of 16 °C. Aggregate formation also depended on both zoospore concentration and depth of suspension.

Leucine Regulates Zoosporic Germination and Infection by Phytophthora erythroseptica
Frontiers in Microbiology, 2019 Pink rot (Phytophthora erythroseptica) of potato is a major concern in many potato production regions. The pathogen produces zoospores that serve as a primary inoculum for infection.

Marine Drugs, 2017 Little is known about the role of chemotaxis in the location and attachment of chytrid zoospores to potential diatom hosts. Hypothesizing that environmental stress parameters affect parasite-host recognition, four chytrid-diatom tandem cultures ...

Movements of Zoospores of Phytophthora capsici
Japanese Journal of Phytopathology, 1966 A new photometrical device for measuring the tactic aggregation of zoospores of Phytophthora capsici Leon. is described in this paper.An annular diaphragm (×100) of Nikon phase contrast microscope was employed for dark ground illumination and reflected light intensity in the microscopic field was measured by an ordinary exposure meter for microscopic ...

Binding of isovaleraldehyde, an attractant, to zoospores of the fungus Phytophthora palmivora in relation to zoospore chemotaxis [PDF]
Journal of Cell Science, 1981 ABSTRACT The interaction of isovaleraldehyde, an attractant, with zoospores of the fungus Phytoph-thora palmivora was investigated by using binding techniques. The amount of isovaleraldehyde bound diminished with time, an effect that may be related to sensory adaptation.

THERMAL VARIATION FOR GROWTH OF ZOOSPORES OF Albugo spp.
Revista de Agricultura Neotropical, 2018 The objective of this work was to identify the time of the thermal shock that promotes the greater release of zoospores/sporangia. The experiments were carried out with five treatments, varying the thermal variation time (20', 30', 40', 50' and 60') of ...
