What are oomycetes, and to which kingdom do they belong?
They are stramenopilous water molds, not members of kingdom Fungi.
Which source is cited for oomycete hyphae and absorptive nutrition?
Beakes and Sekimoto, 2009.
What primarily composes oomycete cell walls?
Cellulose and β-1,3 and β-1,6 glucans.
What flagella do motile oomycete cells have?
Two heterokont flagella.
What is the ploidy of Oomycete somatic nuclei?
Diploid.
What resistant sexual spore forms as a diploid zygote after oosphere fertilization?
An oospore.
What ploidy and reproductive role characterize a zoospore?
A diploid asexual dispersal spore.
How are oomycete zoospores flagellated?
They have a tinsel flagellum bearing mastigonemes and a whiplash flagellum.
What is a zoosporangium?
A modified hypha, usually terminal and delimited by a septum, that produces zoospores.
What role can deciduous zoosporangia serve?
They can act as dispersal agents.
