A quantitative PCR (QPCR) assay based on the use of SYBR Green I was developed to
assess the abundance of specific groups of picoeukaryotes in marine waters. Six primer sets …

Microbes are dominant drivers of biogeochemical processes, yet drawing a global picture of
functional diversity, microbial community structure, and their ecological determinants …

Marine plankton support global biological and geochemical processes. Surveys of their
biodiversity have hitherto been geographically restricted and have not accounted for the full …

exhibit latitudinal trends in their … richness, which we did not assess here because of its strong …

Picoeukaryotes are a taxonomically diverse group of organisms less than 2 micrometers in
diameter. Photosynthetic marine picoeukaryotes in the genus Micromonas thrive in …

… not be performed for PRAS06, but the probe did not show any nonspecific labeling with the
strains tested. PRAS01, PRAS03, and PRAS05 hybridized only target strains, but not all … not …

There is increasing awareness that many terrestrial and aquatic organisms are not strictly
heterotrophic or autotrophic but rather mixotrophic. Mixotrophy is an intermediate nutritional …

The interrogation of genetic markers in environmental meta-barcoding studies is currently
seriously hindered by the lack of taxonomically curated reference data sets for the targeted …

Species interaction networks are shaped by abiotic and biotic factors. Here, as part of the
Tara Oceans project, we studied the photic zone interactome using environmental factors and …

… This is probably because our samples are not from silicate-replete conditions where
diatoms were blooming. Furthermore, our analysis did not incorporate data from high latitudes, …
