SAR supergroup

Ammonia tepida, a foraminifer with fang prepare pseudopodia

Sar is a taxon of exclusively single-celled organism that will be provided to eukaryotes ( organisms with nuclei ). It comprises the three groups of Stramenopile, Alveolata and Rhizaria, from whose initials SAR, the name was formed.

Features

The taxon is purely phylogenetically defined and demarcated as the lowest common clade to the three extant species Bigelowiella natans Moestrup & Sengco 2001 as a representative of the Rhizaria, Tetrahymena thermophila Nanney & McCoy 1976 for Thalassiosira pseudonana Alveolata and Cleveland in 1873 as Stramenopile.

She closes in return the clades to humans ( Homo sapiens Linnaeus 1758) as representatives of the Opisthokonta to Dictyostelium discoideum Raper 1935 for the Amoebozoa, Arabidopsis thaliana ( Linnaeus) Heynhold 1842 for Archaeplastida, Euglena gracilis Klebs in 1883 for the excavata and Emiliania huxleyi ( Lohmann ) Hay & Mohler in Hay et al. 1967 from the Haptophyta by definition.

Taxonomy

The name dates back to 2007 by Jehanzeb Burki in the context of phylogenetic studies for the first time used acronym SAR, which was formed from the initial letters of the groups present. The acronym was formally described to the usual qualifier for the group and then in 2012 by Sina Adl in his revision of the classification of eukaryotes taxon in the letters ' Sar '.

Sar is the sister taxon of Archaeplastida. It comprises three groups:

• Stramenopile
• Alveolata
• Rhizaria
