The paper shows that cnidarian stinging cells, specifically spirocytes, are highly conserved over 600 million years, while nematocytes show more diversification, controlled by the FoxL2 gene.

The paper identifies an evolutionary rewired gene regulatory network in stony corals that specifies secretory cells, using chromatin profiling and transcriptomics in Astrangia poculata.

The paper compares feeding and catch tentacles in two sea anemone species to show how catch tentacles achieve their unique aggressive function through distinct cell and tissue dynamics.

The paper uses ATAC-seq to analyze chromatin accessibility during embryonic development in Hofstenia miamia, identifying regulatory mechanisms and gene networks involved in differentiation.

The paper identifies a lineage-specific gene, kj, essential for efficient sperm entry into eggs in Drosophila melanogaster, with no detectable sequence similarity to other proteins.

This study identifies a de novo gene, atlas, essential for male fertility in Drosophila by facilitating chromatin condensation in spermatids, and reveals its complex evolutionary history.
