Importance of organism and transcriptomesDinoflagellates and bacteria are intimately associated in the marine environment, and many bacteria can break down phytoplankton-derived dimethylsulfonium compounds, like DMSP. L. polyedra also produces some of the lesser known dimethylsulfonium derivatives, including gonyauline and/or gonyol. We are interested in how the production of these compounds as well as the interaction between dinoflagellates and bacteria vary under different conditions (i.e. light versus dark). This work will also provide insight into multi-derivative-dimethylsulfonium-producing dinoflagellates (i.e., those that produce sulfonium compounds other than DMSP) and the fate of these compounds in the oceans and atmosphere.
