Klebsormidiales
Klebsormidiales is an order of charophyte algae. It is the only order in the class Klebsormidiophyceae, sister of the Phragmoplastophyta. , AlgaeBase accepted two families in the order: * Elakatotrichaceae Hindák *Klebsormidiaceae The Klebsormidiaceae are a family containing five genera of charophyte green alga forming multicellular, non-branching filaments.

Klebsormidiaceae
The Klebsormidiaceae are a family containing five genera of charophyte green alga forming multicellular, non-branching filaments. The genus '' Chlorokybus'' was previously included as well, but this problematic and poorly known genus is now placed in a separate class Chlorokybophyceae. Klebsormidiaceae are the sister to the Phragmoplastophyta. Their ancestor was probably a multicellular freshwater green algae, and multicellularity will be retained in all of its descendants except the Zygnematophyceae, which reverted back to unicellularity. Together with the unicellular Chlorokybophytina (Mesostigmatophyceae, ''Spirotaenia'' and Chlorokybophyceae), they comprise the Streptophyta. The genera '' Koliella'' and '' Raphidonema'' were formerly classified as close relatives of ''Klebsormidium'', based on similarities in cell division. However, analysis of both nuclear and chloroplast DNA shows that both of these genera belong to the class Trebouxiophyceae and are not charophytes. '' In ...

Phragmoplastophyta
The Phragmoplastophyta (Lecointre & Guyader 2006) are a proposed sister clade of the Klebsormidiaceae in the Streptophyte/Charophyte clade. The Phragmoplastophyta consist of the Charophycaea and another unnamed clade which contains the Coleochaetophyceae, Zygnematophyceae, Mesotaeniaceae, and Embryophytes (land plants). It is an important step in the emergence of land plants within the green algae. It is equivalent to the ZCC clade/grade, cladistically granting the Embryophyta. The mitosis of Phragmoplastophyta takes place via a phragmoplast. Another synapomorphy In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to hav ... of this clade is the synthesis of cellulose microfibrils by a complex of octameric cellulose synthetases. This complex crosses the plasma membrane and polymerizes mole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klebsormidium Bilatum
''Klebsormidium'' is a genus of filamentous charophyte green algae comprising 20 species. The name was proposed in 1972 to resolve confusion in application and status of Hormidium and was given for the German botanist Georg Albrecht Klebs. The algae occurs mostly in soil and on moist substrates, nevertheless, aquatic and one marine species are also known. Many ''Klebsormidium''-species are able to synthesize substances for UV protection, the so-called mycosporine-like amino acids. The draft genome sequence of ''Klebsormidium flaccidum'' was published in 2014. Species The valid species currently considered to belong to this genus are: * '' Klebsormidium acidophilum'' * '' Klebsormidium bilatum'' * ''Klebsormidium crenulatum'' * ''Klebsormidium dissectum'' * ''Klebsormidium drouetii'' * ''Klebsormidium elegans'' * ''Klebsormidium fluitans'' * ''Klebsormidium fragile'' * ''Klebsormidium klebsii'' * ''Klebsormidium lamellosum'' * ''Klebsormidium montanum'' * ''Klebsormidium mu ...

Charophyta
Charophyta () is a group of freshwater green algae, called charophytes (), sometimes treated as a division, yet also as a superdivision or an unranked clade. The terrestrial plants, the Embryophyta emerged within Charophyta, possibly from terrestrial unicellular charophytes, with the class Zygnematophyceae as a sister group. The clade Streptophyta may be formed by placing Embryophyta within the Charophyta. The Embryophyta may already be included in the Charophyta, in which case it is a synonym of the Streptophyta. The sister group of the charophytes are the Chlorophyta. In some charophyte groups, such as the Zygnematophyceae or conjugating green algae, flagella are absent and sexual reproduction does not involve free-swimming flagellate sperm. Flagellate sperm, however, are found in stoneworts ( Charales) and Coleochaetales, orders of parenchymatous charophytes that are the closest relatives of the land plants, where flagellate sperm are also present in all except the coni ...

AlgaeBase
AlgaeBase is a global species database of information on all groups of algae, both marine and freshwater, as well as sea-grass. History AlgaeBase began in March 1996, founded by Michael Guiry. Text was copied from this source, which is available under Attribution 4.0 International (CC BY 4.0)licence. (Sehere. By 2005, the database contained about 65,000 names. In 2013, AlgaeBase and the Flanders Marine Institute (VLIZ) signed an end-user license agreement regarding the Electronic Intellectual Property of AlgaeBase. This allows the World Register of Marine Species (WoRMS) to include taxonomic names of algae in WoRMS, thereby allowing WoRMS, as part of the Aphia database, to make its overview of all described marine species more complete. Synchronisation of the AlgaeBase data with Aphia and WoRMS was undertaken manually until March 2015, but this was very time-consuming, so an online application was developed to semi-automate the synchronisation, launching in 2015 in conju ...

Green Algae Orders
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while red ...
