Microalgae are important primary producers and form the basis for the marine food web. As global climate changes, so do salinity levels that algae are exposed to. A metabolic response of algal cells partly alleviates the resulting osmotic stress. Some metabolites involved in the response are well...

Collodaria (Radiolaria) are widespread marine planktonic protists that host photosynthetic microalgal symbionts. Within this photosymbiosis, they can contribute substantially to primary production, particularly in oligotrophic ocean regions. Despite their ecological importance, the mechanisms und...

Marine planktonic Radiolaria harboring symbiotic microalgae are ubiquitous in the oceans and abundant in oligotrophic areas. In these low-nutrient environments, they are among the most important primary producers. Systematic studies of radiolarian biology are limited because radiolaria are non-cu...
