Abstract
The crustacean genus Daphnia holds a key position in aquatic ecosystems rendering it an important model organism in environmental research. Its enormous sensitivity to environmental changes is often accompanied by complex plastic responses resulting in different phenotypes from the same genetic background. This plasticity enables Daphnia to survive in heterogeneous environments. The molecular underpinning of these responses are of general interest as they may not only reveal mechanisms of plastic adaptation but also help to predict the impact of global environmental changes. Proteomics is especially suitable to analyse such molecular mechanisms, as proteins are the functional key players of most biochemical processes. In this review, we highlight crucial methodological steps for performing high-quality Daphnia proteomics. Furthermore, we report proteome studies which are able to link genotype and phenotype for a variety of plastic traits, emphasizing the great potential of Daphnia as a model organism for studying the effects of fluctuating and changing environments.
