Metamonad - Wikipedia
网页The metamonads are a large group of flagellate amitochondriate microscopic eukaryotes. They include the retortamonads, diplomonads, parabasalids, oxymonads, and a range of more poorly studied taxa, most of which are free-living flagellates.

网页2021年12月20日 — The inclusion of Anaeramoebae in phylogenomic analyses leads to a crucial rearrangement of the higher-order metamonad relationships; the two fundamental groups within Metamonada appear to be an Anaeramoebae+Parabasalia clade and a Fornicata+Barthelona+Preaxyostyla group. The discovery and robust phylogenetic placement of the Anaeramoebae within ...

网页2020年9月9日 — Transcriptomic data generated from one Barthelona strain (PAP020) were used for large-scale, multi-gene phylogenetic (phylogenomic) analyses. Our analyses robustly placed strain PAP020 at the base of the Fornicata clade, indicating that barthelonids represent a deep-branching metamonad clade.

网页2016年10月6日 — The presence of the complete ADI pathway is widespread in metamonads, protists that specifically inhabit low-oxygen environments. In most of the phylogenies, metamonad taxa branch close to each other, but they never form an exclusive clade.
网页All metamonads thrive in low-oxygen environments and lack classical aerobic mitochondria, instead possessing mitochondrion-related organelles (MROs) with metabolisms that are adapted to low-ox-ygen conditions.
