The cosmopolitan diatomsThalassiosiraandChaetocerosoften dominate phytoplankton communities in marinesystems. Past studies of diatom-bacterial associations have employed community-level methods and culture-based or natural diatom populations. Although bacterialassemblages attached to individual diatoms represents tight associations little is knownon their makeup or interactions. Here, we examined the epibiotic bacteria of 436Thalassiosiraand 329Chaetocerossingle cells isolated from natural samples andcollection cultures, regarded here as short- and long-term associations, respectively.Epibiotic microbiota of single diatom hosts was analyzed by cultivation and by cloning-sequencing of 16S rRNA genes obtained from whole-genome amplification products.The prevalence of epibiotic bacteria was higher in cultures and dependent of the hostspecies. Culture approaches demonstrated that both diatoms carry distinct bacterialcommunities in short- and long-term associations. Bacterial epibonts, commonlyassociated with phytoplankton, were repeatedly isolated from cells of diatom collectioncultures but were not recovered from environmental cells. Our results suggest thatin controlled laboratory culture conditions bacterial{\textendash}diatom and bacterial{\textendash}bacterialinteractions select for a simplified, but specific, epibiotic microbiota shaped and adaptedfor long-term associations.}, keywords = {2018, Chaetoceros, diatoms, diversity, heterotrophic bacteria, interactions, microbiome, rcc, RCC2560, RCC2565, Thalassiosira, Western English Channel}, issn = {1664-302X}, doi = {10.3389/fmicb.2018.02879}, url = {https://www.frontiersin.org/article/10.3389/fmicb.2018.02879/full}, author = {Crenn, Klervi and Duffieux, Delphine and Jeanthon, Christian} } @article {Balzano2012, title = {Composition of the summer photosynthetic pico and nanoplankton communities in the Beaufort Sea assessed by T-RFLP and sequences of the 18S rRNA gene from flow cytometry sorted samples}, journal = {The ISME journal}, volume = {6}, number = {8}, year = {2012}, note = {ISBN: 1751-7362 tex.mendeley-tags: 2012,rcc,sbr?hyto$_\textrmd$ipo}, pages = {1480{\textendash}1498}, abstract = {The composition of photosynthetic pico and nanoeukaryotes was investigated in the North East Pacific and the Arctic Ocean with special emphasis on the Beaufort Sea during the MALINA cruise in summer 2009. Photosynthetic populations were sorted using flow cytometry based on their size and pigment fluorescence. Diversity of the sorted photosynthetic eukaryotes was determined using terminal-restriction fragment length polymorphism analysis and cloning/sequencing of the 18S ribosomal RNA gene. Picoplankton was dominated by Mamiellophyceae, a class of small green algae previously included in the prasinophytes: in the North East Pacific, the contribution of an Arctic Micromonas ecotype increased steadily northward becoming the only taxon occurring at most stations throughout the Beaufort Sea. In contrast, nanoplankton was more diverse: North Pacific stations were dominated by Pseudo-nitzschia sp. whereas those in the Beaufort Sea were dominated by two distinct Chaetoceros species as well as by Chrysophyceae, Pelagophyceae and Chrysochromulina spp.. This study confirms the importance of Arctic Micromonas within picoplankton throughout the Beaufort Sea and demonstrates that the photosynthetic picoeukaryote community in the Arctic is much less diverse than at lower latitudes. Moreover, in contrast to what occurs in warmer waters, most of the key pico- and nanoplankton species found in the Beaufort Sea could be successfully established in culture.}, keywords = {2012, ASSEMBLE, Chaetoceros, MALINA, Pyramimonas, rcc, SBR$_\textrmP$hyto$_\textrmD$PO, sbr?hyto$_\textrmd$ipo, Souchotheque}, issn = {1751-7362}, doi = {10.1038/ismej.2011.213}, author = {Balzano, Sergio and Marie, Dominique and Gourvil, Priscillia and Vaulot, Daniel} }
