"SEND (sex, energy, nutrients, defense): a power toolkit for dinoflagellates to thrive" 

Abstract: 

Diatoms and dinoflagellates are two major groups of phytoplankton that play pivotal roles in marine biogeochemistry. Dinoflagellates are ecologically very successful, occupying diverse econiches. While diatoms dominate spring blooms in the temperate seas, dinoflagellates often succeed diatom blooms and dominate the late spring to summer phytoplankton assemblages. Besides, dinoflagellates are major contributors of coral reef growth, harmful algal blooms, and marine biotoxin. Yet our understanding on how a dinoflagellate gains competitive advantages and thrive in their diverse habitats is still very limited. While diatom ecology has benefited from genomics and functional genetics, such contemporary molecular tools are not as accessible for dinoflagellates. Nevertheless, recent (slow but steady) advances have brought insights into how dinoflagellates regulate gene expression, acquire resources, and adapt to their life style (e.g. symbiosis with corals). I will use some of the latest discoveries as examples to explore what a toolkit a dinoflagellate may possess to grow its population into a bloom condition.
