Cryptochrysis is a formerly recognized genus of cryptomonads first proposed by Adolf Pascher in 1911. He initially treated it as the sole genus in family Cryptochrysidaceae, but later treated it as a member of the Cryptochrysideae subfamily of Cryptomonadaceae, along with Rhodomonas, Chroomonas, and Cyanomonas. [1] [2] In 1967, R.W. Butcher relegated the group to a subgenus within Chroomonas. [3]

It is now regarded as paraphyletic, with its species now various reassigned into Pyrenomonas and Rhinomonas since 1988. [4]

Noctilucales Order of single-celled organisms

The Noctilucales are an order of marine dinoflagellates. They differ from most others in that the mature cell is diploid and its nucleus does not show a dinokaryotic organization. They show gametic meiosis.

Cryptomonas is the name-giving genus of the Cryptomonads established by German biologist Christian Gottfried Ehrenberg in 1831. The algae are common in freshwater habitats and brackish water worldwide and often form blooms in greater depths of lakes. The cells are usually brownish or greenish in color and are characteristic of having a slit-like furrow at the anterior. They are not known to produce any toxins. They are used to feed small zooplankton, which is the food source for small fish in fish farms. Many species of Cryptomonas can only be identified by DNA sequencing. Cryptomonas can be found in several marine ecosystems in Australia and South Korea.

<i>Generaloberst</i> Rank in the armed forces and police of Nazi Germany, Austria-Hungary, and East Germany

A Generaloberst was the second-highest general officer rank in the German Reichswehr and Wehrmacht, the Austro-Hungarian Common Army, the East German National People's Army and in their respective police services. The rank was equal to a four-star full general but below a general field marshal. The rank was equivalent to a Generaladmiral in the Kriegsmarine until 1945 or to a Flottenadmiral in the Volksmarine until 1990. It was the highest ordinary military rank and the highest military rank awarded in peacetime; the higher rank of general field marshal was awarded only in wartime by the head of state. In general, a Generaloberst had the same privileges as a general field marshal.

Yellow-green algae Class of algae

Yellow-green algae or the Xanthophyceae (xanthophytes) are an important group of heterokont algae. Most live in fresh water, but some are found in marine and soil habitats. They vary from single-celled flagellates to simple colonial and filamentous forms. Xanthophyte chloroplasts contain the photosynthetic pigments chlorophyll a, chlorophyll c, β-carotene, and the carotenoid diadinoxanthin. Unlike other heterokonts, their chloroplasts do not contain fucoxanthin, which accounts for their lighter colour. Their storage polysaccharide is chrysolaminarin. Xanthophyte cell walls are produced of cellulose and hemicellulose. They appear to be the closest relatives of the brown algae.

The Minister of Transport is a cabinet member in the Government of France. The position was created in 1870 as a modification of that of the Minister of Public Works (1830–1870). It has frequently been combined with the positions of Minister of Public Works, Minister of Housing (Logement), Minister of Tourism, Minister of Territorial Development and Minister of the Sea.

Archamoebae Phylum of protists

The Archamoebae are a group of protists originally thought to have evolved before the acquisition of mitochondria by eukaryotes. They include genera that are internal parasites or commensals of animals. A few species are human pathogens, causing diseases such as amoebic dysentery. The other genera of archamoebae live in freshwater habitats and are unusual among amoebae in possessing flagella. Most have a single nucleus and flagellum, but the giant amoeba Pelomyxa has many of each.

Cryptophyceae Class of single-celled organisms

The cryptophyceae are a class of algae, most of which have plastids. About 220 species are known, and they are common in freshwater, and also occur in marine and brackish habitats. Each cell is around 10–50 μm in size and flattened in shape, with an anterior groove or pocket. At the edge of the pocket there are typically two slightly unequal flagella.

Pyrenomonadaceae Family of cryptomonads

Pyrenomonadaceae is a family of cryptomonads which includes three or four known genera. They are distinguished from other cryptomonads by their nucleomorphs being imbedded into the pyrenoid, and the presence of distinctive pigment phycoerythrin 545.
