Endoderm- vs ectoderm-specific expression of symbiosis genes in the snakelocks sea anemone

ABSTRACT: Transcriptional comparison between endodermal and ectodermal compartment in symbiotic sea anemones Anemonia viridis were analysed in several specimens. We generated an oligonucleotide microarray (2000 selected features), which is to date the only available oligonucleotide array for symbiotic cnidarians. We were able to identify a subset of genes clearly involved in symbiosis. RNA was extracted from ectodermal or endodermal samples were prepared from 4 symbiotic specimens. Hybridizations were performed against a single reference (VBl) in a dye-swap experiment.

Trophic endosymbiosis between anthozoans and photosynthetic dinoflagellates forms the key foundation of reef ecosystems. Dysfunction and collapse of symbiosis lead to bleaching (symbiont expulsion), which is responsible for the severe worldwide decline of coral reefs. Molecular signals are central to the stability of this partnership and are therefore closely related to coral health. To decipher inter-partner signaling, we developed genomic resources (cDNA library and microarrays) from the symbi  ...[more]
