BACKGROUND Marine ecosystems are composed of a diverse array of life forms, the
majority of which are unicellular—archaea, bacteria, and eukaryotes. The power of these …

Interactions between microorganisms and clay minerals are ubiquitous in nature and are
involved in the formation and transformation of clay minerals and the global cycles of many …

Background Metagenomics is revolutionizing the study of microorganisms and their
involvement in biological, biomedical, and geochemical processes, allowing us to …

Chloroplast function is orchestrated by the organelle's intricate architecture. By combining
cryo-focused ion beam milling of vitreous Chlamydomonas cells with cryo-electron …

Abstract The Jiaozhou Bay as a model marine ecosystem in China has been intensively
investigated over the last 90 years. However, detailed phytoplankton community …

Symbioses between nitrogen (N) 2–fixing prokaryotes and photosynthetic eukaryotes are
important for nitrogen acquisition in N-limited environments. Recently, a widely distributed …

Biological interactions underpin the functioning of marine ecosystems, be it via competition,

Marine picocyanobacteria, comprised of the genera Synechococcus and Prochlorococcus,
are the most abundant and widespread primary producers in the ocean. More than 20 …

Grazing rate estimates indicate that approximately half of the bacterivory in oligotrophic
oceans is due to mixotrophic flagellates (MFs). However, most estimations have considered …

Oligotrophic subtropical gyres are the largest oceanic ecosystems, covering> 40% of the
Earth's surface. Unicellular cyanobacteria and the smallest algae (plastidic protists) …
