Peroxisomes in parasitic protists
Molecular and Biochemical Parasitology, 2016Representatives of all major lineages of eukaryotes contain peroxisomes with similar morphology and mode of biogenesis, indicating a monophyletic origin of the organelles within the common ancestor of all eukaryotes. Peroxisomes originated from the endoplasmic reticulum, but despite a common origin and shared morphological features, peroxisomes from ...

Protists and protist-microbe interactions in soil chips
2022<p>Soil organisms live and interact in the intricate soil pore space labyrinth, but their natural habitat and natural interactions are difficult to study because of the opaqueness of the soil. We recently developed microfluidic model systems that simulate the spatial microstructure of soil microbial habitats in a transparent material ...

AbstractNuclear dualism, i.e. the occurrence of two nuclei, different in structure and function within the same cell, is a phenomenon restricted to the heterokaryotic Foraminifera and to the ciliates. Though interesting similarities exist, there is no doubt that the phenomenon developed independently in both groups.In the Foraminifera whose taxonomy is

This review focuses on selected papers that illustrate an historical perspective and the current knowledge of myosin structure and function in protists. The review contains a general description of myosin structure, a phylogenetic tree of the myosin classes, and descriptions of myosin isoforms identified in protists. Each myosin is discussed within the

DNA sequencing is faster and cheaper than ever before but quantity does not necessarily mean quality. Towards a comprehensive understanding of the microbial biosphere, we need more reference genomes from single-celled eukaryotes (protists) across the full breadth of eukaryotic diversity.

AbstractIn my opinion, the problem of accounting for the origin of eucaryotic cells cannot be dissociated from the problem of accounting for the origin of mitosis. A primeval cell type could not become eucaryotic unless it had concurrently evolved a method for reliably partitioning its genetic material.Modern procaryotes perhaps had their genetic ...

Microsporidia: emerging pathogenic protists
Acta Tropica, 2001Microsporidia are eukaryotic spore forming obligate intracellular protozoan parasites first recognized over 100 years ago. These organisms infect all of the major animal groups and are now recognized as opportunistic pathogens of humans. Microsporidian spores are common in the environment and microsporidia pathogenic to humans have been found in water ...
