Genomic analysis of the tryptome reveals molecular mechanisms of gland cell evolution

Understanding the drivers of morphological diversity is a persistent challenge in evolutionary biology. Here, we investigate functional diversification of secretory cells in the sea anemone Nematostella vectensis to understand the mechanisms promoting cellular specialization across animals.We demonstrate regionalized expression of gland cell subtypes in the internal ectoderm of N. vectensis and show that adult gland cell identity is acquired...
