Symbiodinium Genome

Research Area 1: SymbiOmics - Decoding Structure and Function of the coral metaorganism

Details


We are currently completing sequencing, assembly, and annotation of the coral hologenome of Stylophora pistillata, a cosmopolitan and common coral species that serves as a physiological model system in numerous studies. The availability of the complete gene set encoded in the genomes of the coral animal, the dinoflagellate symbiont, and the associated bacteria promises an unprecedented view on the composition, structure, and function of coral metaorganisms. These data will contribute to our understanding of the contribution of each holobiont member species and how it relates to metaorganism function. To this date, we have analyzed and published the transcriptomes of S. pistillata and its symbiont Symbiodinium microadriaticum. In addition to characterizing the expressed gene set, these studies were the first to identify and characterize miRNAs and the associated RNAi machinery in a coral and a Symbiodinium symbiont. We have also sequenced and published the microbiome of the coral Stylophora pistillata. This work has revealed a prevalent group of bacteria in the genus Endozoicomonas that reside deep within the coral tissue.
