Journal ArticleDOI
Application of denaturing gradient gel electrophoresis (DGGE) to study the diversity of marine picoeukaryotic assemblages and comparison of DGGE with other molecular techniques.
TL;DR: The prasinophyte group appeared to be the most abundant group in the surface Mediterranean samples as determined by the authors' molecular analyses, and the DGGE method provided a reasonably detailed view of marine picoeukaryotic assemblages and allowed tentative phylogenetic identification of the dominant members.
Journal ArticleDOI
Study of genetic diversity of eukaryotic picoplankton in different oceanic regions by small-subunit rRNA gene cloning and sequencing.
TL;DR: The diversity of marine picoeukaryotes was determined by sequencing cloned 18S rRNA genes in five genetic libraries from North Atlantic, Southern Ocean, and Mediterranean Sea surface waters, and the phylogenetic diversity in each library was rather great, and each library included many different OTUs and members of very distantly related phylogenetic groups.
Journal ArticleDOI
Changes in archaeal, bacterial and eukaryal assemblages along a salinity gradient by comparison of genetic fingerprinting methods in a multipond solar saltern.
Emilio O. Casamayor,Ramon Massana,Susana Benlloch,Lise Øvreås,Beatriz Díez,Victoria Goddard,Josep M. Gasol,Ian Joint,Francisco Rodriguez-Valera,Carlos Pedrós-Alió +9 more
TL;DR: Although the particular taxonomic composition of microbial communities inhabiting a multipond solar saltern could vary among protocols, the general structure of the microbial assemblages was maintained.
Journal ArticleDOI
Unveiling the organisms behind novel eukaryotic ribosomal DNA sequences from the ocean.
TL;DR: One lineage accounted for up to 46% (average during an annual cycle, 19%) of heterotrophic flagellates in a coastal environment, providing evidence that novel stramenopiles are important and unrecognized components of the total stock of bacterial grazers.
Journal ArticleDOI
Functional convergence of microbes associated with temperate marine sponges
Marta Ribes,Eroteida Jiménez,Gitai Yahel,Paula López-Sendino,Beatriz Díez,Beatriz Díez,Ramon Massana,Jonathan H. Sharp,Rafael Coma +8 more
TL;DR: In this paper, the authors identified and quantified the microbial communities associated with three common Mediterranean sponge species, Dysidea avara, Agelas oroides and Chondrosia reniformis (Demospongiae), that cohabitate coralligenous community.
