Protist diversity in a marine and lacustrine system: Patterns across a salinity gradient.
Vis sammendrag
During the last decade, the improvement of high-throughput sequencing (HTS) techniques has substantially increased our insight into microbial ecology, by capturing a much more detailed picture of their diversity. Due to the increasing amount of data obtained by HTS methods, specific questions on the biogeography and factors explaining the distribution of these microorganisms can now be fully examined. Here, the composition and structure of a metabolically active benthic protistan community was investigated along a salinity gradient of closely associated marine and freshwater systems. Amplicons of rDNA and rRNA, were sequenced using the Illumina MiSeq technology. This approach seemed to successfully capture the majority of the protist community in these habitats. The marine environments displayed a higher species richness compared to the lacustrine systems investigated, and a considerable difference in protist composition was observed between marine and freshwater systems. Nevertheless, some protists were found in both saline and freshwater environments, indicating the ability to survive rather diverse environmental conditions. It is noteworthy that some of the OTUs from both habitats form putative new clades in the enigmatic X-cell group.

Analysis of expressed sequence tags from the ichtyotoxic dictyochophyte Pseudochattonella farcimen.
Vis sammendrag
Pseudochattonella farcimen (Eikrem, Edvardsen, et Throndsen) is an ichthyotoxic alga within the Dictyochophyceae (Heterokonta), which has been shown to form blooms in Scandinavian waters every year since 1998. To improve our understanding of the biology of this alga and to facilitate future genomic studies, we report the sequencing and analysis of >10,000 expressed sequence tags (ESTs) corresponding to 8149 unique sequences from this species.
A direct comparison with EST libraries from other heterokonts revealed several functional categories to be significantly overrepresented among the P. facimen ESTs, such as genes involved in cell communication, transporters, or genes targeted to cell organelles. Interestingly, P. farcimen ESTs also code for a high proportion (1.4%) of proteins related to fatty acid metabolism, including eight fatty acid desaturases and two phospholipase A2 genes. Three of the desaturases belong to a family of delta-4 desaturases, known so far only from haptophytes, where they catalyze the conversion of n3-docosapentaenoic (n3-DPA) acid to docosahexaenoic acid (DHA). These findings may partially explain the unusual fatty acid profiles observed in P. farcimen and are discussed both from an evolutionary point of view and in relation the ichthyotoxic effects of this alga.

The Choanozoan Ministeria vibrans: Multigene Phylogeny and the Origin of Animals.
Vis sammendrag
Ministeria vibrans is a unicellular protozoan belonging to the phylum Choanozoa, the evolutionary closest related group to the animals.
Ministeria is a minute bacteria-eating cell possessing slender radiating tentacles, that has recently been shown to be the most close relative to Capsaspora, another protozoan with thread-like (filose) tentacles. Forming the novel clade Filasterea, Ministeria/Capsaspora was shown to be sister to animals and choanoflagellates. Presumably, their last common ancestor evolved filose tentacles well before they were aggregated as a periciliary collar in the choanoflagellates. Several successive evolutionary innovations occurred among the unicellular closest relatives of the animals prior to the origin of multicellularity.
We have analysed an EST library from this early branching choanozoan organism and have found many domains of key significance for animal cell biology. New domain combinations as well as domain duplications must have taken place along the path to multicellularity.
