Abeoforma Whisleri

picture info	Abeoforma Whisleri ''Abeoforma whisleri'' is a single-celled eukaryote that belongs to the Ichthyosporea clade, a group of protists closely related to animals. ''A. whisleri'' was isolated from the digestive tract of a marine invertebrate, specifically the filter-feeding mussel ''Mytilus'' sp''.'' ''A. whisleri'' has a very complex life-cycle, yet to be resolved. It includes several different cell stages, ranging from amoeboidal, hyphal-like and plasmodial stages, which can present filopodia-like (pseudopodia) structures. They also present coenocytic spherical stages with prominent vacuoles and several nuclei. All of those stages undergo dramatic morphological changes and have a cell wall (except for the amoeboid stage). Taxonomy ''A. whisleri'' is a member of the Ichthyosporea clade, within the Teretosporea, which is the earliest branching holozoan lineage. Applications A. whisleri can easily be cultured axenically in marine broth medium. Given its phylogenetic position as a close unicellula ...

picture info	Eukaryota Eukaryotes () are organisms whose Cell (biology), cells have a cell nucleus, nucleus. All animals, plants, fungi, and many unicellular organisms, are Eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the Three-domain system, three domains of life. Bacteria and Archaea (both prokaryotes) make up the other two domains. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the Asgard (archaea), Asgard archaea. This implies that there are only Two-domain system, two domains of life, Bacteria and Archaea, with eukaryotes incorporated among archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass (ecology), biomass is estimated to be about equal to that of prokaryotes. Eukaryotes emerged approximately 2.3–1.8 billion years ago, during the Proterozoic eon, likely as Flagellated cell, flagellated phagotrophs. The ...

picture info	Holozoa Holozoa is a group of organisms that includes animals and their closest single-celled relatives, but excludes fungi. ''Holozoa'' is also an old name for the tunicate genus ''Distaplia''.'' Because Holozoa is a clade including all organisms more closely related to animals than to fungi, some authors prefer it to recognizing paraphyletic groups that mostly consists of Holozoa minus animals. Perhaps the best-known holozoans, apart from animals, are the choanoflagellates, which strongly resemble the collar cells of sponges, and so were theorized to be related to sponges even in the 19th century. ''Proterospongia'' is an example of a colonial choanoflagellate that may shed light on the origin of sponges. The affinities of the other single-celled holozoans only began to be recognized in the 1990s. The sub-classification Ichthyosporea or Mesomycetozoea contains a number of mostly parasitic species. The amoeboid genera ''Ministeria'' and ''Capsaspora'' may be united in a group call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Ichthyosporea The Mesomycetozoea (or DRIP clade, or Ichthyosporea) are a small group of Opisthokonta in Eukaryote, Eukaryota (formerly protists), mostly parasites of fish and other animals. Significance They are not particularly distinctive morphologically, appearing in host tissues as enlarged spheres or ovals containing spores, and most were originally classified in various groups as fungi, protozoa, or colorless algae. However, they form a coherent group on molecular trees, closely related to both animals and fungus, fungi and so of interest to biologists studying their origins. In a 2008 study they emerge robustly as the sibling-group of the clade Filozoa, which includes the animals. Huldtgren et al., following x-ray tomography of microfossils of the Ediacaran Doushantuo Formation, has interpreted them as mesomycetozoan spore capsules. Terminology The name DRIP is an acronym for the first protozoa identified as members of the group, Thomas Cavalier-Smith, Cavalier-Smith later treated the ...

	Teretosporea Teretosporea are a proposed basal Holozoa clade in which Ichthyosporea and Corallochytrium emerged with the Filozoa as sister clade. Since it is close to the divergence between the main lineages of Fungi and Animals, the study of Teretosporea can provide crucial information on the divergent lifestyles of these groups. With the inclusion of '' Syssomonas'' there remained very little support for the Teretosporea, and ''Corralychtrium'' appears to be a more derived Holozoa. The alternate phylogeny is the Pluriformea Pluriformea is a proposed sibling clade of the Filozoa, and consists of '' Syssomonas multiformis'' and the Corallochytrea.
