  Brown algae (Phaeophyceae) are habitat-forming species in coastal ecosystems and include kelp forests and seaweed beds that support a wide diversity of marine life. Host-associated microbial communities are an integral part of phaeophyte biology, and whereas the bacterial microbial partners have received considerable attention, the microbial eukaryotes associated with brown algae have hardly been studied. Here, we used broadly targeted “pan-eukaryotic” primers (metabarcoding) to investigate brown algal-associated eukaryotes (the eukaryome). Using this approach, we aimed to investigate the eukaryome of seven large brown algae that are important and common species in coastal ecosystems. We also aimed to assess whether these macroalgae harbor novel eukaryotic diversity and to ascribe putative functional roles to the host-associated eukaryome based on taxonomic affiliation and phylogenetic placement. We detected a significant diversity of microeukaryotic and algal lineages associated with the brown algal species investigated. The operational taxonomic units (OTUs) were taxonomically assigned to 10 of the eukaryotic major supergroups, including taxonomic groups known to be associated with seaweeds as epibionts, endobionts, parasites, and commensals. Additionally, we revealed previously unrecorded sequence types, including novel phaeophyte OTUs, particularly in the Fucus spp. samples, that may represent fucoid genomic variants, sequencing artifacts, or undescribed epi-/endophytes. Our results provide baseline data and technical insights that will be useful for more comprehensive seaweed eukaryome studies investigating the evidently lineage-rich and functionally diverse symbionts of brown algae.

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.
