Taxonomic and functional annotation of particle metaproteomes from three selected time points during the bloom. (A) The proportion of bacterial proteins increased during the course of the bloom (B) Eukaryotic proteins made up the majority of identified proteins and showed an initial strong dominance of Bacillariophyta (C). Functional annotation of metaproteomes indicated a high contribution of metabolism-related eukaryotic proteins early in the bloom, while cellular processes and signaling increased during later time points.
