Neochloris is a genus of green algae in the family Neochloridaceae. [1] It is found in freshwater aquatic and terrestrial soil habitats. [2]
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). [3] Each cell has a single parietal chloroplast with one to several pyrenoids. [2]
Neochloris reproduces asexually. Reproduction occurs via aplanospores or zoospores. Zoospores bear two flagella; upon spore germination, the zoospore loses its flagella and becomes spherical. [4]
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. [3] Species once placed in Neochloris have now been placed in two segregate genera, Ettlia and Parietochloris . [3]
Ettlia and Parietochloris differ from Neochloris in being uninucleate while Neochlorissensu stricto contains multinucleate cells. [3] 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, [3] those of Ettlia are arranged in a clockwise orientation, and those of Parietochloris are arranged in a counterclockwise orientation. [3]
The species Neochloris aquatica may have potential as a biological control agent against mosquitoes, specifically Culex quinquefasciatus . [5]
Chlamydomonas is a genus of green algae consisting of about 150 species of unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". Chlamydomonas is used as a model organism for molecular biology, especially studies of flagellar motility and chloroplast dynamics, biogenesis, and genetics. One of the many striking features of Chlamydomonas is that it contains ion channels (channelrhodopsins) that are directly activated by light. Some regulatory systems of Chlamydomonas are more complex than their homologs in Gymnosperms, with evolutionarily related regulatory proteins being larger and containing additional domains.
Polytoma is a genus of flagellates in the family Chlamydomonadaceae. Algae are similar to the genus Chlamydomonas, but lack chlorophyll and are colorless. Although they are not photosynthetic, they are grouped with the green algae because they are phylogenetically related to, and derived from, flagellate green algae.
Atractomorpha is a genus in the Sphaeropleaceae, a family of green algae. The genus name is derived from Greek and means "spindle-shaped" or "arrow-shaped", and refers to the shape of the cells.
Bracteacoccus is a genus of green algae, the sole genus of the family Bracteacoccaceae. It is a terrestrial alga commonly found in soils, from the tropics to the poles.
Carteria is a genus of green algae in the family Chlamydomonadaceae. Carteria are similar in morphology to the common genus Chlamydomonas and differ by having four, rather than two, flagella at the vegetative stage.
Characium is a genus of green algae in the family Characiaceae. It is very commonly found in freshwater habitats, where it is attached to phytoplankton or zooplankton.
Chlamydocapsa is a genus of green algae, specifically of the Chlorophyceae.
Chloromonas is a genus of green algae in the family Chlamydomonadaceae. It is closely related to the model green algae, Chlamydomonas, and traditionally has been distinguished mainly through the absence of a pyrenoid.
Dictyochloris is a genus of green algae in the class Chlorophyceae. It is the sole genus of the family Dictyochloridaceae. It is commonly found in terrestrial and subaerial habitats.
Lobocharacium is a genus of green algae in the family Characiosiphonaceae. It contains the single species Lobocharacium coloradoense. It has been isolated from a pond in Colorado, United States.
Lobomonas is a genus of green algae in the family Chlamydomonadaceae, found in freshwater habitats. Although it is widely distributed, it is a rare genus.
Schroederia is a genus of green algae in the family Schroederiaceae. Schroederiaceae is a monotypic taxon; Schroederia is its only genus.
Sorastrum is a genus of green algae in the family Hydrodictyaceae. It is a component of the phytoplankton of freshwater ponds, lakes, and ditches. Sorastrum is common in tropical to temperate regions of the world, but due to its small size it is often overlooked.
Sphaeroplea is a genus of green algae in the family Sphaeropleaceae. It was first circumscribed by the Swedish botanist Carl Adolph Agardh in 1824.
Vitreochlamys is a genus of green algae in the family Chlamydomonadaceae. It is sometimes known by the name Sphaerellopsis, published by Aleksandr Arkadievich Korshikov. However, that name is an illegitimate later homonym, preceded by SphaerellopsisM.C.Cooke. It is commonly found in freshwater habitats.
Chlorotetraedron is a genus of green algae, in the family Neochloridaceae. The name may also be written as Chlorotetraëdon. It is found as freshwater plankton or in soil.
Follicularia is a genus of green algae, in the family Schizochlamydaceae. It is found in terrestrial habitats, mainly soil.
Cecidochloris is a green algae genus in the family Chlorangiellaceae. It occurs in freshwater. However, it has only been reported so far from Europe, with an additional species from India that is incompletely described.
Bracteamorpha is a genus of green algae in the order Sphaeropleales, and is the only genus in the family Bracteamorphaceae. It contains a single species, Bracteamorpha trainorii.
Apiocystis is a genus of algae belonging to the family Tetrasporaceae. It is found attached to freshwater aquatic algae or plants. The species of this genus are found in Europe and Northern America, and are widespread but generally uncommon.
