The transcriptomic response of the coral Acropora digitifera to a competent Symbiodinium strain: the symbiosome as an arrested early phagosome

Data from the National Center for Biolotechnology Information, Gene Expression Omnibus GEO accession: GSE76976Organism: Acropora digitiferaExperiment type: Expression profiling by high throughput sequencingSummary: Despite the ecological significance of the relationship between reef-building corals and intracellular photosynthetic dinoflagellates of the genus Symbiodinium, very little is known about the molecular mechanisms involved in the establishment of the relationship. Indeed, microarray-based analyses point to the conclusion that host gene expression is largely or completely unresponsive during the establishment of symbiosis with a competent strain of Symbiodinium. In the present study, the use of Illumina RNAseq technology allowed detection of a transient period of differential expression involving a small number of genes (1073 transcripts;
