Mixotrophs are important components of the bacterioplankton, phytoplankton,
microzooplankton, and (sometimes) zooplankton in coastal and oceanic waters. Bacterivory …

Phosphorus (P) is an essential nutrient for marine phytoplankton and indeed all life forms.
Current data show that P availability is growth‐limiting in certain marine systems and can …

While our knowledge about the roles of microbes and viruses in the ocean has increased
tremendously due to recent advances in genomics and metagenomics, research on marine …

Protists, which are single-celled eukaryotes, critically influence the ecology and chemistry of
marine ecosystems, but genome-based studies of these organisms have lagged behind …

The recognition of a new family of rhodopsins in marine planktonic bacteria, proton-pum**
proteorhodopsin, expanded the known phylogenetic range, environmental distribution, and …

Marine microeukaryotes play a fundamental role in biogeochemical cycling through the
transfer of energy to higher trophic levels and vertical carbon transport. Despite their global …

Background Dinoflagellates are taxonomically diverse and ecologically important
phytoplankton that are ubiquitously present in marine and freshwater environments. Mostly …

Although gene regulation can occur at both transcriptional and epigenetic (microRNA)
levels, combined transcriptomic and microRNAomic responses to environmental stress are …

Proton-pump rhodopsin (PPR) in marine microbes can convert solar energy to bioavailable
chemical energy. Whereas bacterial PPR has been extensively studied, counterparts in …

Abstract Pigments absorbing 350–1,050 nm radiation have had an important role on the
Earth for at least 3.5 billion years. The ion pum** rhodopsins absorb blue and green …
