Differential accumulation of algal biotoxins within diploid and triploid Pacific Oysters and Sydney Rock Oysters. The major commercial shellfish in NSW, Sydney rock oysters and Pacific oysters, can accumulate paralytic shellfish toxins with potentially severe human health impacts. This project will determine the impacts of ocean climate change on toxin uptake and metabolism, and investigate its genetic basis in a native oyster species.
Can lateral gene transfer lead to ecological innovation in eukaryotes? The role of saxitoxin in the diversification of Alexandrium. This project will determine the processes that led to the acquisition and diversification of the genetic basis for a potent neurotoxin, saxitoxin. This project will determine its impact on the evolution of the marine producing organisms and investigate novel genetic methods of toxin detection.
The role of toxin biosynthesis for marine dinoflagellates - an evolutionary ecological approach. Dinoflagellates are a group of microalgae that include coral symbionts and phytoplankton. Many species produce potent toxins that can be a problem in the aquaculture industry. This project will use novel genetic methods to investigate the evolution and ecology of toxin production in a variety of marine dinoflagellates.
