Rozella is a parasitic living genus of Opisthokonta .

features

The representatives are parasites and mainly attack Chytridiomycota and egg fungi . They grow inside their host as a trophic form without a cell wall. At a certain point in time, they transform into thick-walled resting pores or into zoosporangia without cell walls that fill the entire host cell. They are holocarp , so the whole thallus is transformed into the fruiting body.

At least the species Rozella allomycis has some ultrastructural peculiarities: The zoospores have a striped rhizoplast that connects the kinetosome (the basal body of the flagellum ) with a large, spherical mitochondrion . The latter borders on the helmet-shaped nucleus .

Systematics

Their taxonomic classification is controversial. In a molecular genetic study in 2006, Rozella and the Microsporidia formed the first clade to branch off from the other fungi :

Mushrooms	other mushrooms     Rozella     Microsporidia

Due to this lack of clarity, Rozella was later listed as incertae sedis within the fungi , i.e. not assigned to a higher taxon of the fungi.

Later investigations led to even more far-reaching results, according to which Rozella was no longer classified as part of the mushrooms in 2012, but instead forms a taxon called Nucletmycea together with the Nuclearia , Fonticula and the mushrooms .

species

Currently, 24 species are included in the genus Rozella :
