(noun)

A rank in the classification of organisms, below domain and above phylum; a taxon at that rank (e.g. the plant kingdom, the animal kingdom).

  • Historical Overview of Eukaryotes

    • They were given the taxonomic rank of Kingdom (biology) by Linnaeus.
    • Although he included the fungi with plants with some reservations, it was later realized that they are quite distinct and warrant a separate kingdom, the composition of which was not entirely clear until the 1980's.
    • They were given their own kingdom, the Protista, by Ernst Haeckel in 1866.
    • The eukaryotes came to be composed of four kingdoms: Kingdom Protista, Kingdom Plantae, Kingdom Fungi, and Kingdom Animalia.
    • The disentanglement of the deep splits in the tree of life only really got going with DNA sequencing, leading to a system of domains rather than kingdoms as top level rank being put forward by Carl Woese, uniting all the eukaryote kingdoms under the eukaryote domain .

  • Classification of Microorganisms

    • The second largest group is called a kingdom.
    • Five major kingdoms have been described and include prokaryota (e.g. archae and bacteria), protoctista (e.g. protozoa and algae), fungi, plantae, and animalia.
    • A kingdom is further split into phylum or division, class, order, family, genus, and species, which is the smallest group .
    • Domain: Bacteria, Kingdom: Eubacteria, Phylum: Proteobacteria, Class: Gammaproteobacteria, Order: Enterobacteriales, Family: Enterobacteriaceae, Genus: Escherichia, Species: E. coli.

  • Opisthokonts: Animals and Fungi

    • The opisthokonts, or "fungi/metazoa group", are a broad group of eukaryotes, including both the animal and fungus kingdoms, together with the eukaryotic microorganisms that are sometimes grouped in the paraphyletic phylum choanozoa (previously assigned to the protist "kingdom").

  • Phylogeny of the Eukarya

    • Eukaryotes are split into 6, subdivisions, referred to as kingdoms .
    • There is debate about the true constituents of the animal kingdoms.

  • Psychrophilic Crenarchaeota

    • The Crenarchaeota (Greek for "spring old quality") (also known as Crenarchaea or eocytes) are Archaea that have been classified as either a phylum of the Archaea kingdom or a kingdom of its own.

  • The Taxonomic Scheme

    • These ranks range in ascending scale from family to suborder, and upward to order, subclass, class, division/phyla, kingdom and domain.
    • Until the advent of molecular phylogeny the Kingdom Prokaryotae was divided into four divisions, a classification scheme still formally followed by Bergey's manual of systematic bacteriology.The various species differ amongst each other based on several characteristics determined by gram staining, which allowed their identification and classification.

  • Edible Fungi

    • Fungi are eukaryotic organisms that are separated taxonomically in the Fungi kingdom.
    • The kingdom includes yeasts and molds (both microorganisms) and mushrooms.

  • Overview of Proteobacteria

    • Domain: Bacteria, Kingdom: Eubacteria, Phylum: Proteobacteria, Class: Gammaproteobacteria, Order: Enterobacteriales, Family: Enterobacteriaceae, Genus: Escherichia, Species: E. coli.

  • Hosts for Cloning Vectors

    • Domain: Bacteria, Kingdom: Eubacteria, Phylum: Proteobacteria, Class: Gammaproteobacteria, Order: Enterobacteriales, Family: Enterobacteriaceae, Genus: Escherichia, Species: E. coli.

  • Habitats and Energy Metabolism of Crenarchaeota

    • The Crenarchaeota are Archaea that have been classified as either a phylum of the Archaea kingdom, or in a kingdom of its own.
