Pyrenomonadaceae
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. Taxonomy ''Rhodomonas'' was the first genus within today's Pyrenomonadaceae identified, being described in 1898. For most of the 20th century, all other genera now recognized as ''Pyrenomonadaceae'' were placed into various other taxa (ex. ''Rhinomonas fulva'' as ''Cryptochrysis fulva'') Adolf Pascher placed Rhodomonas within his subfamily Cryptochrysideae in 1913. Butcher's highly influential 1967 phylogeny of all then-known Cryptophytes did not recognize ''Rhodomonas'', reclassifying all previously described Rhodomonas species as ''Chroomonas''. Between 1982 and 1986, a series of ultrastructure studies by Uwe J. Santore found considerable morphological inconsistencies within Butcher's ''Chroomonas'', leading him to identify t ...

Rhodomonas Salina
''Rhodomonas'' is a genus of cryptomonads. It is characterized by its red colour, the square-shaped plates of its inner periplast, its short furrow ending in a gullet, and a distinctly shaped chloroplast closely associated with its nucleomorph. Historically, ''Rhodomonas'' was characterized by its red chloroplast alone, but this no longer occurs as its taxonomy has become increasingly based on molecular and cellular data. Currently, there is some debate about the taxonomic validity of ''Rhodomonas'' as a genus and further research is needed to verify its taxonomic status. ''Rhodomonas'' is typically found in marine environments, although freshwater reports exist. It is commonly used as a live feed for various aquaculture species. History of Knowledge Discovery ''Rhodomonas'' was first described by G. Karsten in 1898 as a “strange, swimming organism”. The first indication of ''Rhodomonas’'' existence was Karsten's observation of its proliferation in a sample containing d ...

Cryptophyceae
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. Some exhibit mixotrophy. Characteristics Cryptophytes are distinguished by the presence of characteristic extrusomes called ejectosomes or ejectisomes, which consist of two connected spiral ribbons held under tension. If the cells are irritated either by mechanical, chemical or light stress, they discharge, propelling the cell in a zig-zag course away from the disturbance. Large ejectosomes, visible under the light microscope, are associated with the pocket; smaller ones occur underneath the periplast, the cryptophyte-specific cell surrounding. Except for ''Chilomonas'', which has leucoplasts, cryptophytes have one or two ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
