Influence of rapid environmental changes on cnidaria-dinoflagellate symbioses

My broad research interests concern symbiotic interactions among marine invertebrates in both evolutionary and physiological context. While it is widely admitted that symbiosis is an important driving force of metazoan evolution and of their adaptation to the environment, few studies evoked symbiotic interactions in relation with environmental stresses. Using a multidisciplinary integrated approach (Genomics, Physiology and Cellular biology), my current research focuses on investigating the influence of environmental changes on cnidaria-dinoflagellate symbioses in order to better understand the impact of global warming and ocean acidification in coral reef ecosystems. Recently, functional studies have suggested the key role of multiple cell death pathways, such as apoptosis and autophagy, in the bleaching process. However, despite the importance of bleaching phenomenon, the interconnectivity between these major cellular pathways and physiological responses to rapid environmental changes remains unresolved in the case of coral-dinoflagellate symbiosis. My research aims to specify the influence of various environmental stresses on the physiology of the reef building coral Acropora millepora and the sea anemone Aiptasia spp by investigating the molecular regulation of apoptotic and autophagic cellular processes in order to address different questions such as: Does during an hyperthermic stress, apoptosis and autophagy genes regulation in the host confirm the hypothesis of a “see-saw” relation? Can exposure to others environmental stresses (UVs, pH) modify the molecular cross-talk between apoptosis and autophagy? Increasing our understanding of these cellular pathways controlling cnidaria-dinoflagellate symbiosis will offer key insights into the effects of environmental and climate history on acclimatization and susceptibility of coral reef to bleaching.
