Researchers from Flinders University and the South Australian Genomics Centre (SAGC) are undertaking a whole-genome sequencing project to study Karenia mikimotoi, the microscopic algae suspected to be driving the harmful algal bloom currently impacting South Australia’s coastline.
Supported by Bioplatforms Australia through the National Collaborative Research Infrastructure Strategy (NCRIS), the project will generate the first high-quality reference genome for K. mikimotoi. This genomic resource will help address critical knowledge gaps surrounding the species’ toxicity, bloom dynamics, and ecological impacts.
Led by Dr Michael Doane and Professor Elizabeth Dinsdale from the Flinders Accelerator for Microbiome Exploration (FAME) Lab, in partnership with SAGC experts, the project will apply advanced sequencing and assembly approaches developed through national infrastructure investments. The K. mikimotoi genome is estimated to be around 16 times larger than the human genome, making this sequencing effort a technically challenging but significant milestone for marine research in Australia.
The assembled genome will provide an essential foundation for understanding toxin production, bloom persistence, and the evolutionary traits that allow K. mikimotoi to thrive in changing marine environments. Insights gained through this work will support improved monitoring and management of harmful algal blooms in South Australian waters and beyond.
By enabling rapid access to national genomic platforms and expertise, Bioplatforms Australia is supporting research that strengthens Australia’s capacity to respond to emerging environmental challenges.
