Preparation of Actinoplanes missouriensis Zoospores and Assay for Their Adherence to Solid Surfaces

Bio-Protocol, 2019
Spherical zoospores of a rare actinomycete, Actinoplanes missouriensis, adhere to various hydrophobic solid surfaces by means of type IV pili. The purpose of this protocol is to provide detailed descriptions of the preparation of A.

Chytridiomycosis of Marine Diatoms—The Role of Stress Physiology and Resistance in Parasite-Host Recognition and Accumulation of Defense Molecules [PDF]

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 ...

A review of protocols for the experimental release of kelp (Laminariales) zoospores

Ecology and Evolution, 2019
Kelps (order Laminariales) are foundation species in temperate and arctic seas globally, but they are in decline in many places. Laminarian kelp have an alternation of generations and this poses challenges for experimental studies due to the difficulties

Inhibitory effects of macrotetrolides from Streptomyces spp. on zoosporogenesis and motility of peronosporomycete zoospores are likely linked with enhanced ATPase activity in mitochondria

Frontiers in Microbiology, 2016
The release of zoospores from sporangia and motility of the released zoospores are critical in the disease cycle of the Peronosporomycetes that cause devastating diseases in plants, fishes, animals and humans.

Saprolegnia parasitica S1 and S2 Strains Differ in Zoospore Transition Timing and Pathogenicity Against Juvenile Atlantic Salmon (Salmo salar). [PDF]

J Fish Dis
ABSTRACT S1 and S2 strains of S. parasitica are both common among diseased farmed salmonids in Nova Scotia, whereas globally S1 is rare and S2 is common. Following the initiation of asexual maturation and overnight incubation at 20°C then harvest, and incubation at 10°C in vitro, S2 secondary zoospores mostly transformed into cysts within 3 h, and by 6

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

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 ...

In vitro biocontrol potential of plant extract-based formulation against infection structures of Phytophthora infestans along with lower non-target effects [PDF]

Frontiers in Microbiology
Late blight, caused by Phytophthora infestans, is among the most destructive diseases affecting tomatoes and potatoes. The use of synthetic fungicides is becoming increasingly restricted due to the banning of several active ingredients for environmental ...

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 [PDF]

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.

Membrane proteome analysis identifies key components of sensing in Phytophthora parasitica zoospores [PDF]

Scientific Reports
Phytophthora plant pathogens rely on motile biflagellated zoospores to efficiently locate and colonise host tissues. While rhizospheric signals guiding zoospore movement toward roots are known, the protein composition of membranes mediating these ...
