Most of the genetic, cellular, and biochemical diversity of life rests within single-celled
organisms—the prokaryotes (bacteria and archaea) and microbial eukaryotes (protists) …

Practical experiments drive important scientific discoveries in biology, but theory‐based
research studies also contribute novel—sometimes paradigm‐changing—findings. Here, we …

Microbes gain access to eukaryotic cells as food for bacteria-grazing protists, for host
protection by microbe-killing immune cells, or for microbial benefit when pathogens enter …

Bacteria commonly form aggregates in a range of coral species [termed coral-associated
microbial aggregates (CAMAs)], although these structures remain poorly characterized …

Animals and microorganisms often establish close ecological relationships. However, much
of our knowledge about animal microbiomes comes from two deeply studied groups …

The replication of DNA is a complex biological process that is essential for life. Bacterial
DNA replication is initiated at genomic loci referred to as replication origins (oriC s) …

Global estuarine ecosystems are experiencing severe nitrogen pollution and ocean
acidification (OA) simultaneously. Sedimentary denitrification is an important way of reactive …

The removal of carbon dioxide from the atmosphere by the marine biological pump is a key
regulator of Earth's climate; however, the ocean also serves as a large source of nitrous …

Mitochondria and plastids power complex life. Why some genes and not others are retained
in their organelle DNA (oDNA) genomes remains a debated question. Here, we attempt to …

Anaerobiosis has independently evolved in multiple lineages of ciliates, allowing them to
colonize a variety of anoxic and oxygen‐depleted habitats. Anaerobic ciliates commonly …
