Host or symbiont? Proteomics gives new insights into reef organisms’ reaction to environment stress

Similar to corals, foraminifera in tropical reefs bleach as the water temperature rises. In research, these unicellular organisms can help to investigate the effects of climate change on calcifying organisms. Scientists from Bremen and Dortmund have analysed how tropical foraminifera and their symbiotic algae deal with rising sea temperatures on a molecular level. New proteomics methods have now for the first time enabled them to differentiate between host and symbiont reactions to thermal stress. The results of the project, funded by the Leibniz competition, have been published in the journal Scientific Reports. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)
