A revised six-kingdom system of life is presented, down to the level of infraphylum. [...] Key Result Circumscriptions of the kingdoms Bacteria and Plantae remain unchanged since Cavalier-Smith (1981). The kingdom Fungi is expanded by adding Microsporidia, because of protein sequence evidence that these amitochondrial intracellular parasites are related to conventional Fungi, not Protozoa.Expand
Zooflagellate Phylogeny and the Systematics of Protozoa.
TLDR
The Archezoa are now treated, not as a separate kingdom, but as a subkingdom of the Protozoa, comprising only the two zooflagellate protozoan phyla, Metamonada and Parabasalia, which have no mitochondria and are microaerophilic or anaerobic. Expand
How many kingdoms of life? Eukaryotic phylogeny and philosophy of systematics
According to contemporary understanding of the universal tree of life, the traditionally recognized kingdoms of eukaryotic organisms— Protista, Fungi, Animalia and Plantae—are irregularlyExpand
Only six kingdoms of life

TLDR
Critical interpretation of environmental DNA sequences suggests that the overall picture of microbial biodiversity at phylum or division level is already rather good and comprehensive and that there are no uncharacterized kingdoms of life. Expand
What are Fungi
TLDR
The idea that Fungi form a kingdom distinct from 5 plants and animals became widely accepted only recently, and the organisms traditionally studied by mycologists, and grouped in Whittaker’s kingdom, are polyphyletic. Expand
Hemimastigophora is a novel supra-kingdom-level lineage of eukaryotes
TLDR
Phylogenetic analyses based on single-cell transcriptomic data from two hemimastigotes, a Spironema species and the newly described Hemimastix kukwesjijk, indicate that Hemimastsigophora is a supra-kingdom-level lineage of eukaryotes. Expand
The origin of chloroplasts and the position of eukaryotic algae in the six- kingdom system of life [in Czech]
TLDR
The special interest represents the origin of the chloroplasts, as it was suggested using the molecular methods, the single-celled cyanobacteria were the ancestors of chloroplASTs in glaucophytes, red and green algae. Expand
Taxonomy and Systematics: Current Knowledge and Approaches on the Taxonomic Treatment of Myxomycetes
TLDR
In the present treatment, 64 genera and 980 species are recognized and a revision of the taxonomy and classification, as well as an update on the nomenclature of the group are presented. Expand
The Evolutionary Origin of Animals and Fungi
TLDR
This chapter describes all the major currently known groups of opisthokont protists, what their distinguishing features are, and what are the current ideas as to how they are related to each other. Expand
A new fungal phylum, the Glomeromycota: phylogeny and evolution * * Dedicated to Manfred Kluge (Tech
TLDR
The ecologically and economically important arbuscular mycorrhizal fungi, crucial in the ecology and physiology of land plants, and the endocytobiotic fungus, Geosiphon pyriformis, are phylogenetically analysed by their small subunit (SSU) rRNA gene sequences and placed into a new monophyletic phylum, the Glomeromycota.

The Kingdom Fungi: Heterogeneity of Physiological and Biochemical Properties and Relationships with Plants, Animals, and Prokaryotes (Review)
  • E. Feofilova
  • Biology
  • Applied Biochemistry and Microbiology
  • 2004
TLDR
The heterogeneity of the Fungi kingdom is emphasized, the existence of Oomycota as a separate entity is supported, and the theory of the primitive nature of fungal cells is criticized from the viewpoint of biochemical adaptation. Expand

Eukaryote kingdoms: seven or nine?
TLDR
It is suggested that the best one for general scientific use is a system of seven kingdoms in which the Eufungi and Ciliofungi become subkingdoms of the Kingdom Fungi, and the Cryptophyta andChromophyta subkingdom of th Kingdom Chromista. Expand
The kingdom Protista and its 45 phyla.
TLDR
By presenting taxonomic characterizations as well as relevant nomenclatural data for each taxon described, a comprehensive scheme of overall higher-level classification within the kingdom emerges that may be considered to serve as a solid base or taking-off point for future discussions. Expand
Biodiversity at the molecular level: the domains, kingdoms and phyla of life.
The results of comparative sequence analysis, mainly of small subunit (SSU) ribosomal (r)RNA sequences, have suggested that all of cellular life can be placed in one of three domains: the Archaea,Expand
Towards a natural system of organisms: proposal for the domains Archaea, Bacteria, and Eucarya.
TLDR
It is proposed that a formal system of organisms be established in which above the level of kingdom there exists a new taxon called a "domain." Life on this planet would be seen as comprising three domains, the Bacteria, the Archaea, and the Eucarya, each containing two or more kingdoms. Expand
The Life-History and Systematic Relations of the Mesozoa
TLDR
Although Hyman noted that most zoologists regard the Mesozoa as degenerate flatworms, she designated the group as a phylum, lower than the sponges in taxonomic status. Expand
Kingdom protozoa and its 18 phyla.
The demarcation of protist kingdoms is reviewed, a complete revised classification down to the level of subclass is provided for the kingdoms Protozoa, Archezoa, and Chromista, and the phylogeneticExpand
The Evolution of Cells
The origin of cells was crucial to the evolution of life: by creating the first discrete organisms it vastly strengthened organismic selection, at the expense of genie and population (group)Expand
New concepts of kingdoms of organisms
TLDR
My purpose in this article is to discuss the merits of two classifications which depart from the traditional two kingdoms, the systems of Copeland (1-3) and Whittaker (4, 5). Expand
Proposals Concerning the Higher Taxa of Bacteria
TLDR
Names are proposed for divisions, classes, and some orders of bacteria that include organisms having a rigid cell wall but do not contain peptidoglycan. Expand
The Origin of Eukaryote and Archaebacterial Cells
TLDR
It is argued that the most primitive eukaryote was a phagotrophic archezoan, with no chloroplasts, no mitochondria, no microbodies, and no stacked smooth cisternae forming a Golgi dictyosome, but possessing a single cilium with a sheaf of rootlet microtubules surrounding the single nucleus that divided by a closed mitosis.
