Elucidating colony bloom formation mechanism of a harmful alga Phaeocystis globosa (Prymnesiophyceae) using metaproteomics

Project description:Phaeocystis is a globally distributed Prymnesiophyceae genus and usually forms massive harmful colony blooms, which impact marine ecosystem, mariculture, human health, and even threaten coastal nuclear power plant safety. However, the mechanisms behind the colony formation from the solitary cells remain poorly understood. Here, we investigated metabolic processes of both solitary and non-flagellated colonial cells of Phaeocystis globosa at different colonial bloom stages using a metaproteomic approach. Temperature was significantly correlated with Phaeocystis colony bloom formation, and the flagellated motile solitary cells with abundant flagellum-associated proteins, such as tubulin and dynein, were the exclusive cellular morphotype at the solitary cell stage featured with temperatures ≥ 21℃. When the temperature decreased to <21℃, tiny colonies appeared and the flagellum-associated proteins were identified lower abundances in both solitary and non-flagellated colonial cells, while proteins involved in biosynthesis, chain polymerization and aggregation of glycosaminoglycan (GAG), a key constituent of gelatinous matrix, were identified higher abundances, indicating the central role of active GAG biosynthesis during the colony formation. Furthermore, light utilization, carbon fixation, nitrogen assimilation, and amino acid and protein synthesis were also enhanced to provide sufficient energy and substrates for GAG biosynthesis. This study highlighted that temperature induced re-allocation of energy and substances toward GAG biosynthesis is essential for colony bloom formation of P. globosa.

Metabolism links nutrient stress and harmful algal bloom formation

Project description:Four species of phytoplankton representing important bloom-forming species from three globally important phyla (Bacillariophyta, Haptophyta, and Ochrophyte) were cultured in this study. These species include the cosmopolitan diatom Chaetoceros affinis CCMP159 (isolated from Great South Bay, NY, USA, 1958), the haptophytes Chrysochromulina polylepis CCMP1757 (isolated from the North Sea 1988) and Gephyrocapsa oceanica RCC1303 (isolated from Arachon Bay, France, Jan 1999), and the raphidophyte Heterosigma akashiwo strain CCMP 2393 (isolated from Rehoboth Bay, Delaware, USA). Cultures were grown under three conditions: nitrogen-stress, phosphorus-stress, and replete conditions. Intracellular metabolites were extracted from cultures and analyzed with targeted and untargeted mass spectrometry-based metabolomics methods.
