The ultrastructure of Carpediemonas membranifera (Eukaryota) with reference to the “excavate hypothesis”

European Journal of Protistology, 1999
Summary The ultrastructure of Carpediemonas membranifera , a small flagellate isolated from marine intertidal sediments, is presented for the first time. This protist has two flagella inserting at the anterior end of a feeding groove. The posterior flagellum bears three vanes. The cell has an anterior nucleus, a single dictyosome and a hydrogenosome-

Light Stress Proteins in Viruses, Cyanobacteria and Photosynthetic Eukaryota

2011
Plants in Nature frequently perceive environmental extremes such as light stress. To maintain their physiological functions under light stress conditions plants have developed different protection strategies that operate at morphological, anatomical and subcellular levels.

Homologous Protein Domains in Superkingdoms Archaea, Bacteria, and Eukaryota and the Problem of the Origin of Eukaryotes

Biology Bulletin, 2005
The distribution of protein domains was analyzed in superkingdoms Archaea, Bacteria, and Eukaryota. About a half of eukaryotic domains have prokaryotic origin. Many domains related to information processing in the nucleocytoplasm were inherited from archaea.

Evoluce skupiny Retortamonadida (Eukaryota: Excavata: Fornicata)

2010
Retortamonads (Retortamonadida; genera Chilomastix and Retortamonas) are a small group of protists comprising intestinal commensals of both vertebrates and invertebrates and one free-living species of the genus Chilomastix. Molecular phylogenetic studies showed that retortamonads are closely related to diplomonads, Carpediemonas, Dysnectes ...

New genomic insights into ciliates with loricae (Eukaryota: Alveolata)

Zoological Journal of the Linnean Society
Abstract Several ciliate taxa have evolved loricae as an adaptation for survival in specific environments. Previous studies of loricate ciliates have focused mainly on morphological and functional properties, whereas the molecular evolutionary biology of this particular group of ciliates, especially at the genomic level, has been ...

Origin of eukaryota from Cyanobacterium: membrane evolution theory

1994
It has been currently estimated that the life generated about four billion years ago in the primitive sea as a result of the chemical evolution. There is no doubt that, at that time, the protoorganism was a prokaryotic monad, formed from a certain aggregate of primitive proteins, nucleic acids, and other macromolecules and wrapped with (phospho)lipid ...

Unveiling hidden parasite diversity: Long-read mitogenomics in Eimeriidae and Haemosporida (Eukaryota: Apicomplexa)

International Journal for Parasitology
Mitochondrial genomes of apicomplexan parasites exhibit remarkable structural diversity, ranging from highly reduced linear molecules to circular-mapping concatemers, yet their full characterization has been hindered by technical limitations in resolving complex infections.

Comprehensive phylogenomic analyses of ciliated protists with a revised classification of the phylum Ciliophora (Eukaryota, Alveolata)

Science China Life Sciences
Phylogenomic analyses are instrumental in enhancing our comprehension of evolutionary relationships across the tree of life. Among eukaryotes, ciliates are one of the most diverse groups of single-cell eukaryotes that play important roles in microbial food webs and have been used as important model organisms in a wide range of studies.
