Auranticordis
''Auranticordis'' is a genus of rare tetraflagellate eukaryotic organisms within the phylum Cercozoa. Currently there is only one characterized species within this genus: ''Auranticordis quadriverberis.'' ''Auranticordis'' cells are heart shaped and can range from 35 - 75 μm long and 25 - 70 μm wide. These cells move in a forward gliding motion, and are predators in interstitial marine sand habitats. ''Auranticordis'' cells contain several features that are unique and dissimilar from other cercozoans, such as black bodies, reduced acristate mitochondria (both features that may indicate a preference to a semi-anoxic habitat), putative primary endosymbionts, many orange pigmented extrusomes and the absence of permanently condensed chromosomes. Etymology The heart-like cell shape and orange colouration of ''Auranticordis quadriverberis'' are the basis for the genus name. The latin words ''aurantium'' and ''cordis'' mean "orange" and "heart", respectively. Type species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMC Microbiology
BioMed Central (BMC) is a United Kingdom-based, for-profit scientific open access publisher that produces over 250 scientific journals. All its journals are published online only. BioMed Central describes itself as the first and largest open access science publisher. It was founded in 2000 and has been owned by Springer, now Springer Nature, since 2008. History BioMed Central was founded in 2000 as part of the Current Science Group (now Science Navigation Group, SNG), a nursery of scientific publishing companies. SNG chairman Vitek Tracz developed the concept for the company after NIH director Harold Varmus's PubMed Central concept for open-access publishing was scaled back. The first director of the company was Jan Velterop. Chemistry Central was established in 2006 and the PhysMath Central journal imprint in 2007. In 2002, the company introduced article processing charges, and these have since been the primary source of revenue. In 2007 Yale University Libraries stopped s ...

Rhizaria Genera
The Rhizaria are an ill-defined but species-rich supergroup of mostly unicellular eukaryotes. Except for the Chlorarachniophytes and three species in the genus Paulinella in the phylum Cercozoa, they are all non-photosynthethic, but many foraminifera and radiolaria have a symbiotic relationship with unicellular algae. A multicellular form, ''Guttulinopsis vulgaris'', a cellular slime mold, has also been described. This group was used by Cavalier-Smith in 2002, although the term "Rhizaria" had been long used for clades within the currently recognized taxon. Being described mainly from rDNA sequences, they vary considerably in form, having no clear morphological distinctive characters (synapomorphies), but for the most part they are amoeboids with filose, reticulose, or microtubule-supported pseudopods. In the absence of an apomorphy, the group is ill-defined, and its composition has been very fluid. Some Rhizaria possess mineral exoskeleton (thecae or loricas), which is in differ ...
