Neochloris
Neochloris is a genus of green algae in the family Neochloridaceae. It is found in freshwater aquatic and terrestrial soil habitats. Description
Neochloris consists of spherical cells that are solitary or sometimes found in small clusters. The cell wall is thin and smooth. Cells are multinucleate (with multiple nuclei). Each cell has a single parietal chloroplast with one to several pyrenoids. Neochloris reproduces asexually. Reproduction occurs via aplanospores or zoospores. Zoospores bear two flagella; upon spore germination, the zoospore loses its flagella and becomes spherical. Taxonomy
Neochloris was first described by Richard C. Starr in 1955 with a single species Neochloris aquatica, with more species being added by later authors. However, the genus in this circumscription was polyphyletic. Species one placed in Neochloris have now been placed in two segregate genera, Ettlia and Parietochloris. Ettlia and Parietochloris differ from Neochloris in being uninucleate while Neochloris sensu stricto contains multinucleate cells. Additional features of the flagellar apparatus are visible in ultrastructure as well. The basal bodies of the zoospore flagella in Neochloris are arranged directly opposite to each other, those of Ettlia are arranged in a clockwise orientation, and those of Parietochloris are arranged in a counterclockwise orientation. Ecology
The species Neochloris aquatica may have potential as a biological control agent against mosquitoes, specifically Culex quinquefasciatus. References
