Discovery Of Giant Roaming Deep Sea Protist Provides New Perspective On Animal Evolution
Groove-like tracks on the ocean floor made by giant deep-sea single-celled organisms could lead to new insights into the evolutionary origin of animals, says biologist Mikhail "Misha" Matz from The University of Texas at Austin.

Evolution of four gene families with patchy phylogenetic distributions: influx of genes into protist genomes
Recently, phylogenomic analyses of the complete genome sequences of Entamoeba histolytica and Cryptosporidium parvum indicated that several genes of these human parasites most likely had been acquired from prokaryotes.

Mitochondrion-derived organelles in protists and fungi
The mitochondrion is generally considered to be a defining feature of eukaryotic cells, yet most anaerobic eukaryotes lack this organelle.

Acute toxicity of heavy metals towards freshwater ciliated protists
The acute toxicity of five heavy metals to four species of freshwater ciliates (Colpidium colpoda, Dexiotricha granulosa, Euplotes aediculatus, and Halteria grandinella) was examined in laboratory tests.

The new higher level classification of eukaryotes with emphasis on the taxonomy of protists
This revision of the classification of unicellular eukaryotes updates that of Levine et al. (1980) for the protozoa and expands it to include other protists.

In search of the small ones: improved prediction of short exons in vertebrates, plants, fungi and protists
Prediction of the coding potential for stretches of DNA is crucial in gene calling and genome annotation, where it is used to identify potential exons and to position their boundaries in conjunction with functional sites

Improvement of silver impregnation technique (protargol) to obtain morphological features of protists cilitates, flagellates and opalinates
The present work is a variation of the technique of protargol described by Tuffrau (1964, 1967) and was made with some modifications in the laboratory.
