Executive Summary : | Dinoflagellates are marine phytoplanktons that generate valuable oxygen comparable to land plants and have
profound effects on ocean biogeochemical cycles29. Dinoflagellates are also the key drivers of the marine food
web and act as global carbon pumps. Therefore stress factors destabilizing dinoflagellates will not only impact
the global oxygen levels but also impinge on the biogeochemical equilibrium. The ocean pH and temperature
stress have severe impact on dinoflagellate growth, species diversity, harmful algal blooms, decoupling of
dinoflagellate - coral symbiosis5 and differential intra and inter genus response. This encourages thorough
systematic investigation of dinoflagellate systems under stress. This project proposes to understand the molecular
underpinnings of OA and SST’s impact on photosynthesis and nitrogen metabolism in dinoflagellates |
