Chromerid genomes reveal the evolutionary path from photosynthetic algae to obligate intracellular parasites
Insight is provided into how obligate parasites with diverse life strategies arose from a once free-living phototrophic marine alga, and co-regulated with genes encoding the flagellar apparatus supporting the functional contribution of flagella to the evolution of invasion machinery.
Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes
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.
Diversity, nomenclature, and taxonomy of protists.
Evaluating placental inter-ordinal phylogenies with novel sequences including RAG1, γ -fibrinogen, ND6, and mt-tRNA, plus MCMC-driven nucleotide, amino acid, and codon models, plus a phylogenetic foundation for comparative mammalian genomics is evaluated.
Factors mediating plastid dependency and the origins of parasitism in apicomplexans and their close relatives
This work examines the broader distribution of a suite of molecular characteristics previously linked to the origins of apicomplexan parasitism and finds that virtually all are present in their free-living relatives.
Palpitomonas bilix represents a basal cryptist lineage: insight into the character evolution in Cryptista
The taxonomic assignment of P. bilix, and character evolution in Cryptista is discussed, which was found to be basal to a clade of cryptophytes, goniomonads and kathablepharids collectively known as Cryptista, which is proposed to be a part of the larger taxonomic assemblage Hacrobia.
Molecular phylogeny of diplomonads and enteromonads based on SSU rRNA, alpha-tubulin and HSP90 genes: Implications for the evolutionary history of the double karyomastigont of diplomonads
It is suggested that all higher taxa intended to unite multiple enteromonad genera be abandoned, that Trimitus and Enteromonas be considered as part of Hexamitinae, and that the term 'enteromonads' be used in a strictly utilitarian sense.
