The Revised Classification of Eukaryotes
TLDR
This revision of the classification of eukaryotes retains an emphasis on the protists and incorporates changes since 2005 that have resolved nodes and branches in phylogenetic trees.
Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes
TLDR
It is confirmed that eukaryotes form at least two domains, the loss of monophyly in the Excavata, robust support for the Haptista and Cryptista, and suggested primer sets for DNA sequences from environmental samples that are effective for each clade are provided.
Intracellular invasion of green algae in a salamander host
TLDR
The invasion of algae into salamander host tissues and cells represents a unique association between a vertebrate and a eukaryotic alga, with implications for research into cell–cell recognition, possible exchange of metabolites or DNA, and potential congruence between host and symbiont population structures.
Phylogenomics demonstrates that breviate flagellates are related to opisthokonts and apusomonads
TLDR
The balance of evidence suggests that the breviate lineage forms the deepest branch within Obazoa, and a 159-protein supermatrix is constructed, indicating that this protein complex involved in metazoan multicellularity may have evolved earlier in eukaryote evolution than previously thought.
Phylogenomics Places Orphan Protistan Lineages in a Novel Eukaryotic Super-Group
TLDR
CRuMs and ancyromonads represent two distinct major groups that branch deeply on the lineage that includes animals, near the most commonly inferred root of the eukaryote tree, which makes both groups crucial in examinations of the deepest-level history of extant eucaryotes.
Light Microscopic Observations, Ultrastructure, and Molecular Phylogeny of Hicanonectes teleskopos n. g., n. sp., a Deep‐Branching Relative of Diplomonads
TLDR
Hicanonectes teleskopos has a ventral groove and two unequal flagella, and rapidly rotates during swimming, and forms a clade with the deep‐branching fornicate Carpediemonas, with moderate‐to‐strong bootstrap support, although their SSU rRNA gene sequences are quite dissimilar.
Combined morphological and phylogenomic re-examination of malawimonads, a critical taxon for inferring the evolutionary history of eukaryotes
TLDR
The ‘malawimonad+metamonad signal’ in morphological and molecular data argues against a strict Metamonada+Discoba clade, and should not be assumed when inferring deep-level evolutionary history in eukaryotes.
The ultrastructure of Ancyromonas, a eukaryote without supergroup affinities.
Clarifying the Taxonomic Identity of a Phylogenetically Important Group of Eukaryotes: Planomonas is a Junior Synonym of Ancyromonas
TLDR
The rationale for creating the new genus Planomonas is critique, reexamining the original sources and making additional observations using light and electron microscopy, and it is found that almost all the differences between the genera are mistaken or insubstantial.
