THERMAL VARIATION FOR GROWTH OF ZOOSPORES OF Albugo spp. [PDF]

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 ...

An Improved Sporulation Method for Producing Asexual Zoospores of Pythium aphanidermatum on Culture Medium

Mycobiology
An improved sporulation method for Pythium aphanidermatum on 10% V8-juice agar was developed to generate substantial quantities of zoospores. We conducted experiments using a 4 × 4 factorial design to evaluate the effects of temperature (20, 25, 30, and ...

Phytophthora zoospores display klinokinetic behaviour in response to a chemoattractant.

PLoS Pathogens
Microswimmers are single-celled bodies powered by flagella. Typical examples are zoospores, dispersal agents of oomycete plant pathogens that are used to track down hosts and infect.

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.

Gene Expression in Aphelid Zoospores Reveals Their Transcriptional and Translational Activity and Alacrity for Invasion

Journal of Fungi
In Aphelidium insulamus (Opisthokonta, Aphelida) zoospores, the expression of 7708 genes out of 7802 described genes was detected. For 589 of them, expression levels were shown to be more than 10 times higher than the median level.

Genes expressed in zoospores of Phytophthora nicotianae

Molecular Genetics and Genomics, 2003
The genus Phytophthora includes many highly destructive plant pathogens. In many Phytophthora species, pathogen dispersal and initiation of plant infection are achieved by motile, biflagellate zoospores that are chemotactically attracted to suitable infection sites.

Transcriptomic and Ultrastructural Signatures of K⁺-Induced Aggregation in Phytophthora parasitica Zoospores

Microorganisms, 2020
Most pathogenic oomycetes of the genus Phytophthora spread in water films as flagellated zoospores. Zoospores perceive and produce signals attracting other zoospores, resulting in autoaggregation in vitro or biofilm formation on plant surface.

Zoospores-on-a-Chip : the development of a microfluidic platform to measure electrotactic responses of oomycete zoospores. [PDF]

Oomycetes are filamentous microorganisms that are morphologically and nutritionally similar to fungi. Some oomycete species, most notably those in the Phytophthora genus, can become pathogenic, and these can have huge impacts on ecosystems with the potential loss of biodiversity.

Turgor Regulation in Phytophthora Zoospores [PDF]

Oomycetes are significant pathogens responsible for causing various plant and animal diseases, including root rot, potato blight, and kauri dieback, which can lead to substantial biodiversity and economic losses. Their infection strategy includes the production of asexual zoospores, which can play a crucial role in their spread to neighbouring plants ...

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 ...
