Which protist has one eyespot the euglena paramecium or amoeba? What is the phylum of red algae? What type of phytoplankton is responsible for red tide? Of the three broad groups of protists, which are heterotr
Behavior and composition of the microtubular cytoskeleton in a primitive group of protists: The trichomonadsNo abstract is available for this article.doi:10.1016/0248-4900(96)81355-4Delgado, PilarViscogliosi, EricBrugerolle, GuyJohn Wiley & Sons, Ltd.Biology of the Cell...
Studies over the past five years on a primitive group of Protists, the Trichomonads, have led to the biochemical and immunological identification of the major proteins composing the main cytoskeleton structures. According to these results and to additional molecular data, the proteins composing a bro...
The most striking examples of the remodeling of mitochondrial functions in anaerobic protists involve the wholesale replacement of the highly-conserved essential mitochondrial ISC sys- tem by laterally acquired prokaryotic Fe/S cluster biogenesis systems. In the Archamoebae, a two-protein Fe/S ...
Auroralumina may have fed on diver- sifying phytoplankton53 or protists54 but, additionally, may have consumed an emerging zooplankton. The presence of a stem-group medusozoan necessitates the presence of other cnidarians, as well as other early-diverging animal lineages known to have planktonic...
The Parmales is a group of pico-sized marine protists with cells surrounded by silica plates (Booth and Marchant, 1987), first observed by microscopy in oceanic samples (Iwai and Nishida, 1976). Origin- ally, they were thought to be resting stages of silicified loricate choanoflagellates (...
Additional criteria, untested here, may also include a complex wall ultrastructure and a wall chemistry unique to extant eukaryotes: protists (Javaux et al., 2003, Javaux et al., 2004, Marshall et al., 2005). Trachyhystrichosphaera aimika has a very plastic morphology suggesting it may ...
Japan and 3Department of Isotope Biogeochemistry, Helmholtz Centre for Environmental Research - UFZ, Leipzig, Germany Prasinophytes clade VII is a group of pico/nano-planktonic green algae (division Chlorophyta) for which numerous ribosomal RNA (rRNA) sequences have been retrieved from the marine en...

Overlooked for decades, they have recently been characterized as the most species-rich group of known marine protists [1, 2]. Global metabarcoding sur- veys have estimated at least 67,000 species [3], revealing that diplonemids populate not only all biogeographic and pelagic zones of the ...
