Despite the ecological significance of the relationship between reef-building coralsand intracellular photosynthetic dinoflagellates of the genus Symbiodinium, very littleis known about the molecular mechanisms involved in its establishment. Indeed,microarray-based analyses point to the conclusion that host gene expression is largelyor completely unresponsive during the establishment of symbiosis with a competentstrain of Symbiodinium. In this study, the use of Illumina RNA-Seq technologyallowed detection of a transient period of differential expression involving a smallnumber of genes (1073 transcripts; <3% of the transcriptome) 4 h after the exposure of Acropora digitifera planulae to a competent strain of Symbiodinium (a clade B strain).This phenomenon has not previously been detected as a consequence of both thelower sensitivity of the microarray approaches used and the sampling times used. The results indicate that complex changes occur, including transient suppression of mito-chondrial metabolism and protein synthesis, but are also consistent with the hypothesisthat the symbiosome is a phagosome that has undergone early arrest, raising the possi-bility of common mechanisms in the symbiotic interactions of corals and symbiotic seaanemones with their endosymbionts.
