Specialized structures in plants and animals help attract and mediate communication with bacterial symbionts.

A seagrass relies on symbiotic bacteria inside its roots to fix nitrogen. This is the first time scientists have demonstrated that this relationship occurs in a marine plant.

Researchers can now explain how some marine plants obtain their nitrogen.

Scientists have documented examples of corals “remembering” prior exposure to heat stress in the field, and are now simulating these phenomena in the lab to better understand their cellular and molecular underpinnings.

Corals that previously experienced heat stress respond better the next time around. Researchers are trying to figure out how, and hope to one day take advantage of the phenomenon to improve coral restoration efforts. 

The endosymbiont Coxiella affects tick serotonin production and subsequent blood-feeding behavior, a study finds.

Having two different endosymbionts may allow the ciliate Pseudoblepharisma tenue to live in both oxygen-rich and oxygen-poor zones of the muddy bogs of southern Germany.

The transcription of DNA drives the remarkably tidy organization of chromosomes in the dinoflagellate Symbiodinium microadriaticum.

Researchers uncover the “body-snatching” tactics of fungi that flourish immediately after wildfires.

A newly identified group of viruses may help suppress eukaryotes’ immune response and promote tolerance of endosymbiotic bacteria.

Researchers suggest the viruses can help endosymbiotic bacteria get along with their hosts.

The finding that a bacterium within a bacterium within an animal cell cooperates with the host on a biosynthetic pathway suggests the endosymbiont is, practically speaking, an organelle.

Gates was director of the Hawaii Institute of Marine Biology and a strong advocate for coral conservation.

Contrary to some hypotheses, the organelles did not descend from any known lineage of Alphaproteobacteria, researchers find.

Scientists study the unusual genome evolution of the bacteria that live within a genus of cicadas.
