Effects of UV and temperature on gene expression in the snakelocks sea anemone

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.

Epigenomic and transcriptomic profiling of cnidocyte subtypes in the sea anemone Nematostella vectensis [Cut & Tag]

Project description:Cnidarians, including corals, sea anemones, and jellyfish, possess specialized stinging cells called cnidocytes that function in prey capture and defense. These cells represent a striking evolutionary innovation and include distinct types such as venom injecting nematocytes and mechanically acting spirocytes. While their biomechanics and transcriptional regulation have been studied extensively, little is known about their epigenetic regulation. Here, we combined epigenetic profiling with RNA sequencing in the sea anemone Nematostella vectensis to explore regulatory programs underlying cnidocyte diversity. We identified cell type specific regulatory elements in promoter and enhancer regions and linked them to distinct gene expression programs. This analysis revealed fundamental differences between nematocytes and spirocytes and uncovered a previously unrecognized nematocyte population that expresses the nep3 toxin but lacks most other toxins. These findings highlight the complexity of cnidocyte regulation and suggest greater cellular diversity within this defining cnidarian cell type than previously appreciated.

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.

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.
