The Protist Ribosomal Reference database (PR2): a catalog of unicellular eukaryote Small Sub-Unit rRNA sequences with curated taxonomy
TLDR
The presence of both rRNA and rDNA sequences, taking into account introns (crucial for eukaryotic sequences), a normalized eight terms ranked-taxonomy and updates of new GenBank releases were made possible by a long-term collaboration between experts in taxonomy and computer scientists.

Eukaryotic plankton diversity in the sunlit ocean
TLDR
Diversity emerged at all taxonomic levels, both within the groups comprising the ~11,200 cataloged morphospecies of eukaryotic plankton and among twice as many other deep-branching lineages of unappreciated importance in plankton ecology studies.

Strain-specific responses of Emiliania huxleyi to changing seawater carbonate chemistry
Abstract. Four strains of the coccolithophore E. huxleyi (RCC1212, RCC1216, RCC1238, RCC1256) were grown in dilute batch culture at four CO2 levels ranging from ~200 μatm to ~1200 μatm. Growth rate,…

Sensitivity of coccolithophores to carbonate chemistry and ocean acidification
TLDR
The analyses revealed that differentially calcified species and morphotypes are distributed in the ocean according to carbonate chemistry, and the discovery of a heavily calcified Emiliania huxleyi morphotype in modern waters with low pH highlights the complexity of assemblage-level responses to environmental forcing factors.

Extreme diversity in noncalcifying haptophytes explains a major pigment paradox in open oceans
TLDR
Estimates of depth-integrated relative abundance of 19-Hex indicate that haptophytes dominate the chlorophyll a-normalized phytoplankton standing stock in modern oceans, adding to the growing evidence that the evolution of complex microbial eukaryotic cells is a critical force in the functioning of the biosphere.

Pseudo-cryptic speciation in coccolithophores
TLDR
Research on five commonly occurring coccolithophores supports the hypothesis that such variation represents pseudocryptic speciation events, occurring between 0.3 and 12.9 million years ago from a molecular clock estimation, and suggests strong stabilizing selection acting on cocColithophorid phenotypes.

Effects of temperature on photosynthetic parameters and TEP production in eight species of marine microalgae
TLDR
Different responses were observed between species, highlighting the fact that photoacclima- tion mechanisms vary interspecifically for both light har- vesting and downstream photosynthetic metabolism, providing a new outlook on carbon excretion.

The “Cheshire Cat” escape strategy of the coccolithophore Emiliania huxleyi in response to viral infection
TLDR
Resistance of the haploid phase of E. huxleyi provides an escape mechanism that involves separation of meiosis from sexual fusion in time, thus ensuring that genes of dominant diploid clones are passed on to the next generation in a virus-free environment.

On the description of Tisochrysis lutea gen. nov. sp. nov. and Isochrysis nuda sp. nov. in the Isochrysidales, and the transfer of Dicrateria to the Prymnesiales (Haptophyta)
TLDR
This work sequenced partial nuclear small subunit (SSU) and large subunit rDNA and mitochondrial cytochrome oxidase 1 genes of 34 isochrysidacean culture strains and compared molecular phylogenetic inferences with cytological and ultrastructural observations to propose one new genus and two new species of Isochrysidaceae.

Marine protist diversity in European coastal waters and sediments as revealed by high-throughput sequencing.
TLDR
This extensive and systematic sequencing of geographically separated sites provides the most comprehensive molecular description of coastal marine protist diversity to date.
