Outline of Final Research Achievements

Far more intimate knowledge of scleractinian coral biology is essential in order to understand how diverse coral-symbiont endosymbioses have been established, especially the establishment and maintenance of obligate symbiosis. Genomic data undergird studies of all symbiotic processes. We decoded genomes of the coral Acropora digitifera in 2011 and then, during the period of this research, characterized detail gene loss in amino acid metabolism, genes involved in calcification, innate immunity, apoptosis, UV resistance and others. Then, we decoded the Symbiodinium minutum genome in 2013 and characterized expansion of certain gene families, molecular basis for permanently-condensed chromatin, and others. The Symbiodinium plastid and mitochordarial genomes are also decoded. Since many questions regarding the coral-Symbiodinium symbiosis remain, we are now studying the questions one-by-one with the decoded genome information.
