An ancestral mitochondrial DNA resembling a eubacterial genome in miniature
Mitochondria, organelles specialized in energy conservation reactions in eukaryotic cells, have evolved from eubacteria-like endo-symbionts 1–3 whose closest known relatives are the rickettsial groupExpand

A molecular reassessment of the Leptomyxid amoebae.
Leptomyxid amoebae encompass a diverse assemblage of amoeboid protists that have been implicated as encephalitis-causing agents. This characteristic is attributed to recent studies identifying newExpand

The Nucleariid Amoebae: More Protists at the Animal-Fungal Boundary
Abstract Nucleariid amoebae are naked amoebae, generally characterized by a spherical or sometimes flattened body with radiating filopodia. Most species preferentially consume algal prey orExpand

MOLECULAR ASSESSMENT OF ULVA SPP. (ULVOPHYCEAE, CHLOROPHYTA) IN THE HAWAIIAN ISLANDS 1
Sequences of the nuclear internal transcribed spacer 1 (ITS1) region and the chloroplast rbcL gene were obtained from 86 specimens of Ulva (including “Enteromorpha”) from five of the main HawaiianExpand

Ultrastructure of Trimastix pyriformis (Klebs) Bernard et al.: similarities of Trimastix species with retortamonad and jakobid flagellates.
Trimastix pyriformis (Klebs 1893) Bernard et al. 1999, is a quadriflagellate, free-living, bacterivorous heterotrophic nanoflagellate from anoxic freshwaters that lacks mitochondria. MonoprotistExpand

Phylogenetic relationships of green algae assigned to the genus Planophila (Chlorophyta): evidence from 18S rDNA sequence data and ultrastructure
Phylogenetic analyses, based upon nuclear small-subunit ribosomal RNA gene sequences, of four ‘chlorosarcinoid’ species referred to Planophila Gerneck show that the genus is polyphyletic. The typeExpand

Flagellar apparatus absolute orientations and the phylogeny of the green algae.
The absolute orientation of the flagellar apparatus in green algal motile cells is a feature of considerable value in studies of green algal systematics and phylogeny. The absolute orientationExpand

Two New Small-Subunit Ribosomal RNA Gene Lineages within the Subclass Gymnamoebia
Abstract Phylogenetic analysis of small-subunit ribosomal RNA gene sequences for gymnamoebae of the families Vexilliferidae, Paramoebidae, and Vannellidae identified two distinct lineages that areExpand

The Pinguiophyceae classis nova, a new class of photosynthetic stramenopiles whose members produce large amounts of omega‐3 fatty acids
The Pinguiophyceae class. nov., a new class of photo‐synthetic stramenopiles (chromophytes), is described. The class includes five monotypic genera, Glossomastix, Phaeomonas, Pinguiochrysis (typeExpand
