Order (biology)
Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Class (biology)
In biological classification, class ( la, classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders. Other well-known ranks in descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class fitting between phylum and order. History The class as a distinct rank of biological classification having its own distinctive name (and not just called a ''top-level genus'' ''(genus summum)'') was first introduced by the French botanist Joseph Pitton de Tournefort in his classification of plants that appeared in his ''Eléments de botanique'', 1694. Insofar as a general definition of a class is available, it has historically been conceived as embracing taxa that combine a distinct ''grade'' of organization—i.e. a 'level of complexity', measured in terms of how differentiated their organ systems are into distinct regions or sub-organs—with a distinct ''type'' of construc ...

Ignicoccus
''Ignicoccus'' is a genus of hyperthermophillic Archaea living in marine hydrothermal vents. They were discovered in samples taken at the Kolbeinsey Ridge north of Iceland, as well as at the East Pacific Rise (at 9 degrees N, 104 degrees W) in 2000. Systematics According to the comparisons of 16S rRNA genes, ''Ignicoccus'' represents a new, deeply branching lineage within the family of the Desulfurococcaceae. Three species are known: ''I. islandicus'', ''I. pacificus'' and ''I. hospitalis'' strain KIN4I. Cell structure The archaea of the genus ''Ignicoccus'' have tiny coccoid cells with a diameter of about 2 µm, that exhibit a smooth surface, an outer membrane and no S-layer. They have a previously unknown cell envelope structure—a cytoplasmic membrane, a periplasmic space (with a variable width of 20 to 400 nm, containing membrane-bound vesicles), and an outer membrane (approximately 10 nm wide, resembling the outer membrane of gram-negative bacteria). ...

Fervidicoccus
''Fervidicoccus fontis'' is a species of anaerobic organotroph archaeum belonging to the kingdom Thermoproteota. It is thermophilic and slightly acidophilic, being found at the Uzon Caldera at temperatures between 75 °C and 80 °C. Cells are single cocci of 1–3 μm in diameter with no archaella The archaellum (; formerly archaeal flagellum) is a unique structure on the cell surface of many archaea, that allows for swimming motility. The archaellum consists of a rigid helical filament that is attached to the cell membrane by a molecular ....*Perevalova, A.A. ''et al.''

Genome Taxonomy Database
The Genome Taxonomy Database (GTDB) is an online database that maintains information on a proposed nomenclature of prokaryotes, following a phylogenomic approach based on a set of conserved single-copy proteins. In addition to breaking up paraphyletic groups, this method also reassigns taxonomic ranks algorithmically, creating new names in both cases. Information for archaea was added in 2020, along with a species classification based on average nucleotide identity. Each update incorporates new genomes as well as human adjustments to the taxonomy. An open-source Open source is source code that is made freely available for possible modification and redistribution. Products include permission to use the source code, design documents, or content of the product. The open-source model is a decentralized sof ... tool called GTDB-Tk is available to classify draft genomes into the GTDB hierarchy.

The All-Species Living Tree Project
The All-Species Living Tree' Project is a collaboration between various academic groups/institutes, such as ARB Project, ARB, SILVA rRNA database project, and List of Prokaryotic names with Standing in Nomenclature, LPSN, with the aim of assembling a database of 16S ribosomal RNA, 16S rRNA sequences of all validly published species of ''Bacteria'' and ''Archaea''. At one stage, 23S ribosomal RNA, 23S sequences were also collected, but this has since stopped. Currently there are over 10,950 species in the aligned dataset and several more are being added either as new species are discovered or species that are not represented in the database are sequenced. Initially the latter group consisted of 7% of species. Similar (and more recent) projects include the Genomic Encyclopedia of Bacteria and Archaea (GEBA), which focused on whole genome sequencing of bacteria and archaea. Tree The tree was created by maximum likelihood analysis without bootstrap: consequently accuracy is traded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
