Beautiful work on the establishment of symbiosis in anthozoans.

And a good opportunity to re-read an exciting related paper from last year.

Co-option of lysosomal machinery shapes the evolution of the intracellular photosymbiosis supporting coral reefs
Corals harbor intracellular algal symbionts in specialized organelles that enable them to build diverse reef ecosystems. Corals and other cnidarians have repeatedly evolved this symbiosis through the ...

Top: The phylogenetic position of Nematostella and localization of Vasa2 +/Piwi1+ cells within the juvenile polyp body plan. (A) Simplified phylogenetic tree highlighting the phylogenetic position of the sea anemone Nematostella vectensis and other animal taxa relevant for this study. All animal silhouettes are licensed under CC0,1.0 Universal Public domain and taken from https://www.phylopic.org. (B–D) Schematics showing the localization of Vasa2+/Piwi1+ cells in a juvenile polyp, depicted in longitudinal (B) or cross-section (C, D).

Cells can form patterns within themselves just like embryos do. How? Connie Yan's new preprint shows how the anterior-posterior cytoskeleton pattern in Stentor is dictated by regionalized scaffolding proteins

🚨🚨 preprint alert! 🚨🚨
I wish to introduce CARDIB, not the singer, but the protein.
CARDIB=CARD Inhibitory Binding protein.
In our new work we discover this antiviral protein that is found in all Anthozoa (sea anemones and corals 🪸) but not in other animals.

An ancient anthozoan protein reveals an alternative evolutionary path of antiviral signaling
How antiviral immunity first arose in animals is a central question in evolutionary biology. Using the sea anemone Nematostella vectensis, we identify CARDIB, a previously uncharacterized gene located...

Drawing together findings from several projects over many years, we make a case that neural cell types in the Clytia larva have two embryological origins: i-cells and ectodermal.

Separation of the Early gastrula into oral and aboral halves shows that some neural cell tupes derive from aboral ectoderm, and others from i-cells

Our paper on the role of neurons in Nematostella head regeneration is now out at @currentbiology.bsky.social Big thank you to all collaborators, it was a pleasure!

Ectopic head regeneration after nervous system ablation in a sea anemone
Via genetic ablation of neurons, Mazloumi Gavgani et al. show that the nervous system is essential for defining axial polarity during whole-body regeneration in the sea anemone Nematostella vectensis.
