Single Cell Genomics Reveals Viruses Consumed by Marine Protists [PDF]
Frontiers in Microbiology, 2020 The predominant model of the role of viruses in the marine trophic web is that of the “viral shunt,” where viral infection funnels a substantial fraction of the microbial primary and secondary production back to the pool of dissolved organic matter. Here,

Linking extreme seasonality and gene expression in Arctic marine protists [PDF]
Scientific Reports, 2023 At high latitudes, strong seasonal differences in light availability affect marine organisms and regulate the timing of ecosystem processes. Marine protists are key players in Arctic aquatic ecosystems, yet little is known about their ecological roles ...

Assembly processes and functional diversity of marine protists and their rare biosphere [PDF]
Environmental Microbiome, 2023 Background The mechanisms shaping the rare microbial biosphere and its role in ecosystems remain unclear. We developed an approach to study ecological patterns in the rare biosphere and use it on a vast collection of marine microbiomes, sampled in ...

Transcriptome analyses to investigate symbiotic relationships between marine protists. [PDF]
Frontiers in Microbiology, 2015 Rhizaria are an important component of oceanic plankton communities worldwide. A number of species harbour eukaryotic microalgal symbionts, which are horizontally acquired in the environment at each generation.

Experimental assessment of interactions between marine bacteria and model protists: from predator-prey relationships to bacterial-mediated lysis [PDF]
Applied and Environmental MicrobiologyBacteria in aquatic environments are a principal food source for predatory protists. Whereas interactions between bacteria and protists are recognized to determine the pathogenesis and epidemiology of several human pathogens, few studies have ...

Resolving cryptic species complexes in marine protists: phylogenetic haplotype networks meet global DNA metabarcoding datasets. [PDF]
ISME J, 2021 Marine protists have traditionally been assumed to be lowly diverse and cosmopolitan. Yet, several recent studies have shown that many protist species actually consist of cryptic complexes of species whose members are often restricted to particular ...

Contrasting Mixotrophic Lifestyles Reveal Different Ecological Niches in Two Closely Related Marine Protists. [PDF]
J Phycol, 2020 Many marine microbial eukaryotes combine photosynthetic with phagotrophic nutrition, but incomplete understanding of such mixotrophic protists, their functional diversity, and underlying physiological mechanisms limits the assessment and modeling of ...

Swimming, gliding, and rolling toward the mainstream: cell biology of marine protists. [PDF]
Mol Biol Cell, 2019 Marine protists are a polyphyletic group of organisms playing major roles in the ecology and biogeochemistry of the oceans, including performing much of Earth’s photosynthesis and driving the carbon, nitrogen, and silicon cycles.
