Proleptomonadidae
Monadofilosa is a grouping of Cercozoa. (It is sometimes considered one of three, the other two being Phytomyxa and Reticulofilosa.) These organisms are single-celled amoeboid protists. Classification Monadofilosa includes the testaceans, which are testate filose amoeboids, and the cercomonads. It is sometimes described as Testaceafilosia and Sarcomonadea. It has also been described as Sarcomonadea (''Cercomonas, Heteromita, Bodomorpha, Proleptomonas, Allantion''), Thecofilosea (''Cryptodifflugia, Cryothecomonas''), Spongomonadea (''Spongomonas, Rhipidodendron''), and Imbricatea (''Thaumatomonas, Thaumatomastix, Allas, Gyromitus, Euglypha, Trinema, Paulinella''). * The testaceans live both in marine and freshwater habitats, and in mosses. Members include ''Lecythium'', ''Pseudodifflugia'', ''Euglypha'' (a euglyphid), and ''Paulinella chromatophora''. * Cercomonads are flagellates that glide on their posterior cilium and/or generate filopodia. Members of this group contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcomonadea
The sarcomonads () or class Sarcomonadea are a group of amoeboid biciliate protists in the phylum Cercozoa. They are characterized by a propensity to move through gliding on their posterior cilium or through filopodia, a lack of scales or external theca, a soft cell surface without obvious cortical filamentous or membranous skeleton, two cilia without scales or hairs, tubular mitochondrial cristae, near-spherical extrusomes, and a microbody (probably a peroxisome) attached to the nucleus. History In 1993 Cavalier-Smith described the sarcomonads as a subclass known as “Sarcomonadia”, an assemblage of unrelated cercozoans ( thaumatomonads, proteomyxids, cercomonads...) and excavates (jakobids), in the now defunct class “Heteromitea”, in the old phylum “Opalozoa”. This subclass was created to lump together protozoa that have an anisokont type of zoospore (i.e. two cilia of different lengths), are non-thecate and have isodiametric extrusomes. Sarcomonadia was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryothecomonas
Cryomonadida is a group of heterotrophy, heterotrophic Rhizaria, that belong to the Cercozoa. Characteristics Members of the Cryomonadida are single-celled organisms that are surrounded by a shell comprising layers of organic material. They possess two unequally long flagellum, flagella, and a single nucleus (cell), nucleus with a distinct nucleolus. They have a laterally located cytostome, from which pseudopodia arise. Systematics The order (biology), order Cryomonadida was erected in 1993 for the genus ''Cryothecomonas''. In 2005, Sina Adl ''et al.'' did not include the order in their classification, but placed the genus ''incertae sedis'' among the Cercozoa. It became clear, however, that other genera, and taxa known only from environmental DNA, belonged in this group, and so in 2008 Jan Pawlowski placed the Cryomonadida as part of the core Cercozoa. Within the Cercozoa, the sister taxon to Cryomonadida is Ebriacea; ''Pseudodifflugia'' is also closely related. The following ...

Paulinella
''Paulinella'' is a genus of at least eleven species including both freshwater and marine amoeboids. Its most famous members are the three photosynthetic species ''P. chromatophora'', ''P. micropora'' and ''P. longichromatophora'', the first two being freshwater forms and the third a marine form, which have recently (in evolutionary terms) taken on a cyanobacterium as an endosymbiont. As a result they are no longer able to perform phagocytosis like their non-photosynthetic relatives. The event to permanent endosymbiosis probably occurred with a cyanobiont. The resulting organelle is a photosynthetic plastid that is often referred to as a 'cyanelle' or chromatophore, and is the only other known primary endosymbiosis event of photosynthetic cyanobacteria, although primary endosymbiosis with a non-photosynthetic cyanobacterial symbiont have occurred in the diatom family ''Rhopalodiaceae''. The endosymbiotic event happened about 90–140 million years ago in a cyanobacterial species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thaumatomastix
''Thaumatomastix'' is a protist genus of the order ''Thaumatomonadida'', within the phylum Cercozoa and the class Imbricatea. Its species are aquatic, feeding on algae and appearing in waters of a wide range of temperatures and salinities, and are 15-50 micrometers long. They can interchange between flagellated and amoeboid forms, and are notable for being covered in both spiny and flattened siliceous scales. Etymology The genus was named by Robert Lauterborn in 1899. '' Thauma'' in Greek can mean ‘miracle,’ ‘wonder,’ or ‘marvel,’ while ''mastix'' is a suffix (also Greek-derived) that can be used to mean ‘scourge’ or ‘whip,’ which may refer to the organism’s flagella. History of knowledge The genus was first identified in 1899 by Robert Lauterborn, a German protozoologist. Since then several new species have been discovered within the genus. However, analyses of ribosomal DNA have indicated that Thaumatomastix may in fact be a paraphyletic group, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
