Ancylonema
The Mesotaeniaceae are a small family of unicellular green algae known as the "saccoderm desmids". The Mesotaeniaceae appear to be sister or ancestral to the Zygnemataceae. The desmids are a deep branching group of Zygnemataceae. ''Spirotaenia'' was found to be a basal green alga. Genera The Mesotaeniaceae includes the following genera: * ''Ancylonema'' Berggren, 1872 * ''Cylindrocystis'' Meneghini ex De Bary, 1858 * ''Geniculus'' Prescott, 1967 * ''Mesotaenium'' Nägeli, 1849 * ''Netrium'' (Nägeli) Itzigsohn & Rothe, 1856 * ''Nucleotaenium'' Gontcharov & Melkonian, 2010 * ''Planotaenium'' (Ohtani) Petlovany & Palamar-Mordvintseva, 2009 * ''Roya (alga), Roya'' West & G.S.West, 1896 * ''Spirotaenia'' Brébisson, 1848 * ''Tortitaenia'' A.J.Brook, 1998 Synonyms: * ''Endospira'' Brébisson, nom. inval., is a synonym of Spirotaenia * ''Entospira'' Kuntze, 1898 is a synonym of ''Spirotaenia'' * ''Polytaenia'' A.J.Brook, 1997, nom. illeg., is a synonym of ''Tortitaenia'' Refere ...

Zygnemataceae
The Zygnemataceae are a family of filamentous or unicellular, uniseriate (unbranched) green algae. The filaments are septated and reproduction is by conjugation; ''Spirogyra'' is commonly used in schools to demonstrate this kind of reproduction. The family is notable for its diversely shaped chloroplasts, such as stellate in ''Zygnema'', helical in ''Spirogyra'', and flat in ''Mougeotia''. The Zygnemataceae are cosmopolitan, but though all generally occur in the same types of habitats, ''Mougeotia'', ''Spirogyra'', and ''Zygnema'' are by far the most common; in one study across North America, 95% of the Zygnemataceae collected were in these three genera. Classification and identification is primarily by the morphology of the conjugation, which is somewhat rare to find in natural populations of permanent water bodies; when in the vegetative state, the rarer genera resemble the three most common, and are often mistaken for them and catalogued as such. Conjugation can be induced in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spirotaenia Condensata
''Spirotaenia'' is a genus of basal green algae that may be sister to the Chlorokybophyceae. It was previously considered to be part of the Zygnemataceae. It is sexually conjugating, a mode of reproduction that was previously only known in the Zygnemataceae/Mesotaeniaceae, the sister groups to the land plants The Embryophyta (), or land plants, are the most familiar group of green plants that comprise vegetation on Earth. Embryophytes () have a common ancestor with green algae, having emerged within the Phragmoplastophyta clade of green algae as siste .... This is surprising, as ''Spirotaenia'' is much more basal. The conjugating process is substantially aberrant. ''Spirotaenia'' may actually be more than one distinct lineage which may not be closely related. Phylogeny References Green algae {{Alga-stub ...

Green Alga
The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to properly include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. A few other organ ...
