Nanomonadea
Nanomonadea is a class of biciliate phagotrophic, non- photosynthetic free-living opalozoans, coontaining the sole order Uniciliatida. This monophyletic group previously known as clade MAST-3 is characterized by a single hairless posterior cilium and absence of an anterior cilium.

Opalinata
Opalinata is a superclass of non- phagotrophic heterokonts that unites the classes Opalinea and Blastocystea, and is the sister group to Opalomonadea. Description When Opalinata was first erected as a taxon in 1926, it was placed as the sole class in the group "Protociliata" and considered as primitive cilliates due to the fact that they move thanks to their numerous cilia and that they both present two nuclei. They were distinguished because they perform syngamy by the complete fusion of uninucleated gametes, while the rest of ciliates, forming "Euciliata" ( Ciliata + Suctoria), perform syngamy through their micronuclei alone while their macronuclei dissolve. The taxon Opalinata was revised in 1996 by Cavalier-Smith and placed in Opalozoa, and is now defined by the following synapomorphies: gut parasitism and the loss of peroxisomes and phagocytosis. Phylogeny The cladogram below shows the relationships between Opalinata and the rest of Opalozoa. Classification The modern ...

Wobblata
Wobblata is a paraphyletic grouping of all placidozoans except Opalinata. It unites the classes Placididea, Nanomonadea and Opalomonadea. Description Members of this group are ancestrally aerobic phagotrophic biciliates. They have tubular mitochondrial cristae and a hairy anterior cilium The cilium, plural cilia (), is a membrane-bound organelle found on most types of eukaryotic cell, and certain microorganisms known as ciliates. Cilia are absent in bacteria and archaea. The cilium has the shape of a slender threadlike project .... They have a split right microtubular root, i.e. one of the two (left and right) microtubular roots that support the feeding groove is split in two. They lack a cytopharynx, and some of them have lost their anterior cilium. Phylogeny The cladogram below shows the relationships between Wobblata and the rest of Opalozoans.

Proteromonas
''Proteromonas'' is a genus of heterokonts. It lives in the gut of amphibians and reptiles. An example is ''Proteromonas lacertae''. ''Proteromonas'' is notable by location of mastigoneme Mastigonemes are lateral "hairs" that attach to protistan flagella. Flimsy hairs attach to the flagella of euglenid flagellates, while stiff hairs occur in stramenopile and cryptophyte protists.Hoek, C. van den, Mann, D. G. and Jahns, H. ...s not on its flagella, but on posterior part of the cell. Such mastigonemes are called somatonemes.

Heterokont
Heterokonts are a group of protists (formally referred to as Heterokonta, Heterokontae or Heterokontophyta). The group is a major line of eukaryotes. Most are algae, ranging from the giant multicellular kelp to the unicellular diatoms, which are a primary component of plankton. Other notable members of the Stramenopiles include the (generally) parasitic oomycetes, including '' Phytophthora'', which caused the Great Famine of Ireland, and '' Pythium'', which causes seed rot and damping off. The name "heterokont" refers to the type of motile life cycle stage, in which the flagellated cells possess two differently arranged flagella (see zoospore). History In 1899, Alexander Luther created the term "Heterokontae" for some algae with unequal flagella, today called Xanthophyceae. Later, some authors (e.g., Copeland, 1956) included other groups in Heterokonta, expanding the name's sense. The term continues to be applied in different ways, leading to Heterokontophyta being appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opalina
''Opalina'' is a genus of parasitic heterokonts found in the intestines of frogs and toads. They lack mouths and contractile vacuoles, they are covered with nearly equal flagelliform cilia, and they have numerous nuclei, all similar. All the species are obligate endosymbionts, most likely commensal rather than parasitic, in cold-blooded vertebrates. Its body is leaflike in shape. They lack cytostome A cytostome (from ''cyto-'', cell and ''stome-'', mouth) or cell mouth is a part of a cell specialized for phagocytosis, usually in the form of a microtubule-supported funnel or groove. Food is directed into the cytostome, and sealed into vacuol ...s. They are saprozoic, consuming dead matter, which suggests their commensal role. They propagate by means of plasmotomy. The body is flattened, leaf-like and oval in outline and covered by thin pellicle. Nutrition is by pinocytosis. There are several small, spherical and similar sized nuclei present in the endoplasm. The nuclei are e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solenicola
''Solenicola setigera'' is a species of marine stramenopile, and the only species classified within the genus ''Solenicola''. The species ranges between 4–7 µm in diameter and has a complex feeding strategy. Its ecological role within the marine planktonic food chain is generally as a grazer, feeding on photoautotrophic diatoms. It is a parasite of the species '' Leptocylindrus mediterraneus''. ''S. setigera'' will grow on the frustule, the protective shell made of silica, of ''L. mediterraneus'' alongside the cyanobacteria ''Synechococcus ''Synechococcus'' (from the Greek ''synechos'', in succession, and the Greek ''kokkos'', granule) is a unicellular cyanobacterium that is very widespread in the marine environment.
