Here they use scRNA-seq to show that, in the hemichordate Schizocardium californicum, ectoderm and endoderm shift transcriptional identity from larva to adult while mesoderm is transcriptionally conse...

Epithelial cell extrusion in a sea anemone shares key hallmarks with bilaterians and is dynamically regulated by nutritional status. During starvation-induced body shrinkage, extrusion likely contribu...

Coral reefs depend on an intracellular symbiosis between cnidarian hosts and photosynthetic dinoflagellates that is disrupted by ocean warming, causing coral bleaching. Yet how these responses are dis...

Siphonophores (Cnidaria: Hydrozoa) are pelagic colonial marine invertebrates with many highly specialized bodies (zooids) within a single colony. Their unique biology and ecological importance have ma...

Monoamines such as serotonin, dopamine, and tyramine regulate physiological and behavioral processes in bilaterian animals, but the evolutionary origi…

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 ...

Cnidae are explosive harpoon-like organelles localized within stinging cells, or cnidocytes, of the phylum Cnidaria (jellyfish, hydroids, sea anemones, and corals). These unique Golgi-derived vesicula...

Embryonic ‘organizer cells’ can tell embryos of various phyla what kind of body to build.

Experiments using the comb jelly Mnemiopsis leidyi and the sea anemone Nematostella vectensis reveal that the emergence of a core signalling pathway may have been a key innovation enabling the transit...

Computational assessment identifies probe binding errors in a widely used commercial platform for spatial transcriptomics.

Small changes in the non-coding part of the genome have a key role in sex determination.

Abstract. The explosion of body forms found in bilaterians is thought to be tied to the diversification of Hox transcription factors, which play a critical

A chromosome-level brachiopod genome reveals deep conservation of BMP-mediated dorsal–ventral patterning and neural inhibition, suggesting the spiralian ancestor retained the ancestral mechanism in bi...
