Proteomics provides new insights into the reaction of reef organisms to environmental stress

Similar to corals, foraminiferas living in tropical reefs also bleach when exposed to rising water temperatures. In marine sciences, the tiny protozoons can be used as models for researching the effects of climate change on calcium carbonate-producing organisms. Scientists from ZMT (Leibniz Centre for Tropical Marine Research) Bremen, ISAS, and the University of Bremen have now analysed how tropical foraminifera in coral reefs and their symbiotic algae deal with rising temperatures on a molecular level. By applying novel proteomics methods, they were able to distinguish the heat stress reactions of host and symbiont for the first time. The results of this project, which was funded in the scope of the Leibniz competition, have now been published in the journal Scientific Reports.
