The present study was conducted to determine whether A. invadans zoospores show geotactic behaviour compared to other Oomycete genera. |
|
In the first process, zoospores escape from the zoosporangium which is located in the parent algae and they develop into filaments. |
|
This zoosporangium is nearly empty but still contains a few motile zoospores. |
|
For example, copper ions are toxic to the zoospores of grapevine downy mildew, thus preventing infection. |
|
Under these conditions, the overwintering resting spores germinate and can infect plants directly or through the production of zoospores. |
|
Even multicellular chromists, like brown algae and water molds, produce flagellated zoospores of this type. |
|
Oedogonium grows in two different ways, through zoospores, or through syngamy of sperm and egg. |
|
This suggests that infected host cells were negatively selected by the parasite zoospores under these conditions. |
|
The zoospores are disseminated by rain splash to grape tissues where they swim to the vicinity of stomata and encyst. |
|
The initial infection-spreading cells of the fungus, called zoospores, swim by lashing a hair-like flagellum and don't have a cell wall. |
|
As in the related chrytrids, neocallimastigomycetes form zoospores that are posteriorly uniflagellate or polyflagellate. |
|
Germ tubes developed from encysted zoospores within 10-20 minutes after encystment. |
|
Rumen fluid was used for total direct counts of bacterial, protozoa and fungal zoospores using methods of Galyean by haemacytometer. |
