Abstract

Coral cell cultures made from reefbuilding scleractinian corals have the potential to aid in the pursuit of understanding of the cnidarian–dinoflagellate symbiosis Various methods have previously been described for the production of cell cultures in vitro with a range of success and longevity In this study viable tissue spheroids containing host tissue and symbionts coral explants were grown from the tissues of Fungia granulosa The cultured explants remained viable for over 2 months and showed morphological similarities in tissue structure and internal microenvironment to reefbuilding scleractinian corals The photophysiology of the explants 1 week old closely matched that of the parent coral F granulosa This study provides the first empirical basis for supporting the use of coral explants as laboratory models for studying coral symbioses In particular it highlights how these small selfsustaining skeletonfree models can be useful for a number of molecular genetic and physiological analyses necessary for investigating host–symbiont interactions at the microscaleWe would like to thank the two anonymous reviewers for their helpful comments and suggestion for improvements on the manuscript We would like to also extend thanks to Cheryl Woodley Sylvia Galloway Athena Burnett Lisa May and Esti Winter NOAA Charlestown USA for their advice on explant culture methodology We are grateful for the technical assistance of Michael Johnson and Catherine Gorrie from the University of Technology Sydney Corals were collected under the Great Barrier Reef Marine Park Authority permits G11/346701 and G09/317331 issued to PJR SG was supported by an Australian Postgraduate Award APA and research funding was provided by the Plant Functional Biology and Climate Change Cluster C3 and the School of the Environment University of Technology Sydney
