taxon

Examples of taxon in the following topics:

• The International Committee on Taxonomy of Viruses

  • To maintain an ICTV database on the Internet, that records the data that characterize each named viral taxon, together with the common names of each taxon in all major languages.
  • The name of a taxon has no status until it has been approved by ICTV, and names will only be accepted if they are linked to approved hierarchical taxa.
  • If no suitable name is proposed for a taxon, the taxon may be approved and the name be left undecided until the adoption of an acceptable international name, when one is proposed to and accepted by ICTV.
  • Names must not convey a meaning for the taxon which would seem to either exclude viruses which are rightfully members of that taxa, exclude members which might one day belong to that taxa, or include viruses which are members of different taxa.

• Phylogenetic Trees

  • A lineage that evolved early from the root and remains unbranched is called basal taxon.
  • For example, if a branch point was rotated and the taxon order changed, this would not alter the information because the evolution of each taxon from the branch point was independent of the other.
  • A lineage that evolved early and remains unbranched is a basal taxon.

• The Deltaproteobacteria

  • Myxobacteria are included among the delta group of proteobacteria, a large taxon of Gram-negative forms.

• The Levels of Classification

  • The name at each level is also called a taxon.
  • Carnivora is the name of the taxon at the order level; Canidae is the taxon at the family level, and so forth.

• Gammaproteobacteria

  • Phylogenetically, in the Enterobacteriales, several peptidoglycan-less insect endosymbionts form a sister clade to the Enterobacteriaceae, but since they are not validly described, this group is not officially a taxon; examples of these species are Sodalis, Buchnera, Wigglesworthia, Baumannia and Blochmannia.

• Scarlet Fever

  • The T12 virus itself has not been placed into a taxon by the International Committee on Taxonomy of Viruses.

• Phylogeny of the Eukarya

  • Eukaryotes may more formally be referred to as the taxon Eukarya or Eukaryota.

• Starvation-Induced Fruiting Bodies

  • Myxobacteria are included among the delta group of proteobacteria, a large taxon of Gram-negative forms.

• Building Phylogenetic Trees

  • If a characteristic is found in the ancestor of a group, it is considered a shared-ancestral character because all of the organisms in the taxon or clade have that trait .
