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.
Widespread occurrence and genetic diversity of marine parasitoids belonging to Syndiniales (Alveolata).
TLDR
Given the broad distribution of Syndiniales, this work indicates that parasitism may be a major force in ocean food webs, a force that is neglected in current conceptualizations of the marine carbon cycle.
Phylogenetic and Ecological Analysis of Novel Marine Stramenopiles
TLDR
A comparative analysis of novel stramenopiles is carried out, including new sequences from coastal genetic libraries presented here and sequences from recent reports from the open ocean and marine anoxic sites, confirming that they are fundamental members of the marine eukaryotic picoplankton.
Diversity of picoplanktonic prasinophytes assessed by direct nuclear SSU rDNA sequencing of environmental samples and novel isolates retrieved from oceanic and coastal marine ecosystems.
TLDR
A report of the overall diversity of picoeukaryotic prasinophytes reveals a group of ecologically important and diverse marine microorganims that are well represented by isolated cultures.
Phylogenetic analysis of the ‘Nannochloris-like’ algae and diagnoses of Picochlorum oklahomensis gen. et sp. nov. (Trebouxiophyceae, Chlorophyta)
TLDR
It is shown with 1 8S ribosomal DNA (rDNA) sequence phylogeny that 19 of 22 isolates previously assigned to either Nannochloris or Nanochlorum fall within a diverse sister clade to a clade including the four ‘true’ Chlorella species sensu lato, supporting retention of Koliella, Gloeotila, Marvania and Nann Cochloris as distinct genera.
Control of Toxic Marine Dinoflagellate Blooms by Serial Parasitic Killers
TLDR
The authors' observations in natural ecosystems suggest that although bloom-forming dinoflagellates may escape control by grazing organisms, they eventually succumb to parasite attack.
BOLIDOMONAS: A NEW GENUS WITH TWO SPECIES BELONGING TO A NEW ALGAL CLASS, THE BOLIDOPHYCEAE (HETEROKONTA)
TLDR
Analysis of the SSU rDNA gene place the two strains as a sister group to the diatoms, as fucoxanthin is found as the major carotenoid in both lineages, suggesting that the ancestral heterokont that gave rise to thediatom lineage was probably a biflagellated unicell.
Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes
TLDR
It is confirmed that eukaryotes form at least two domains, the loss of monophyly in the Excavata, robust support for the Haptista and Cryptista, and suggested primer sets for DNA sequences from environmental samples that are effective for each clade are provided.
Ecotype diversity in the marine picoeukaryote Ostreococcus (Chlorophyta, Prasinophyceae).
TLDR
Different growth rates and features strongly suggest distinct adaptation to environmental conditions encountered at surface and the bottom of the oceanic euphotic zone, reminiscent of that described in prokaryotes.
