Project description:We monitored gene expression response of the symbiotic sea anemone Anemonia viridis subjected to a thermal and/or UV stress. A symbiosis-dedicated oligonucleotide microarray (2000 selected features) was generated, representing to date the only available oligonucleotide array used for symbiotic cnidarians (GPL10546). We are describing here the expression evolution during the first phase (5 days) of the stress.

Tissue specific differential expression in response to a thermal stress in the snakelocks sea anemone.

Project description:Differential expression between endodermal (zooxanthellate) and ectodermal tissue layers in the endosymbiotic sea anemone Anemonia viridis has been analyzed for 3 specimens subjected to a thermal stress (+10°C) for a 2 days period. A symbiosis-dedicated oligonucleotide microarray (2000 selected features) was generated, representing to date the only available oligonucleotide array used for symbiotic cnidarians (GPL10546). We are describing here the preferential expression in ectoderm vs endoderm (also called epidermis and gastroderm, respectively) during the time course of this thermal stress. RNA was extracted from ectodermal or endodermal dissected tissues. 3 different symbiotic anemones were subjected to a thermal and UV stress (+10°C), sampled at T0, T12h and T36h. Tissue dissections were carried out from tentacles immediately after sampling. For each sample, dye-swap hybridizations compared T0 and later time points. For each time point, statistical analysis combines the 3 biological replicates.

Proteotranscriptomics of the most popular hoast sea anemone Entacmaea quadricolor reveals not all toxin genes expressed are recruited into its venom arsenal

Project description:While the unique symbiotic relationship between anemonefish and sea anemones is iconic, it is still not fully understood how anemonefish withstand and thrive within this venomous host environment. In this study we used a proteotranscriptomics approach to elucidate the proteinaceous toxin repertoire from the most popular host sea anemone Entacmaea quadricolor. Although 1251 different toxin or toxin-like RNA transcripts were expressed in E.quadricolor tentacles and 2736 proteins were detected in milked venom, only 135 (approx. 10%) of proteins in venom were classified as putative toxins. This work raises the perils of defining a dominant venom type based on transcriptomics data alone in sea anemones, as we found that the dominant venom type differed between the transcriptome and proteome data. Moreover, anemonefishes interact with sea anemone proteins, so it is important when determining the dominant toxin type to examine the peptides and proteins that are present in host sea anemone venom and mucus which anemonefishes are known to interact.
