THESIS SUBJECT :
Dynamics of the coral holobionte and transcriptomic plasticity : variability inter individual, inter populational and interspecific
KEY WORDS :

THESIS PROJECT :
In the current context of the global changes, theoretical hypotheses concerning the adaptation of the sessiles longévives sorts(species) emerge and predict that a strategy of plasticity should be selected in the case of populations experimenting fluctuating environments. Nevertheless, the experimental validation and the underlying mechanisms are widely underestimated. The objective of this project is to study this question to marine cnidarians of ecological interest (the tropical scleractinian coral Pocillopora damicornis, the sort(species) mainly sténotherme) and patrimonial (the red coral Corallium rubrum, the sort(species) mainly eurytherme). Considering the consortium of bodies which represent these sorts(species) (cnidarian, symbiote and microbiote associated), we suggest studying the dynamics of the holobionte as well as his(her,its) transcriptomique plasticity by combining(organizing) approaches metagenomics, métatranscriptomiques and transcriptomiques. We suggest leading these approaches not only on our two sorts(species) of interest but also on populations of every sort(species) experimenting more or less fluctuating environments. This interspecific analysis and populational inter will be completed by an analysis of the interpersonal variability in each of these populations.
