This study identifies an XX/XY sex determination system in the cnidarian Hydractinia symbiolongicarpus, establishing it as a model for studying sex determination in non-bilaterian animals.

The paper identifies a family of immunoglobulin superfamily genes in the cnidarian Hydractinia symbiolongicarpus, showing they are homologous to vertebrate histocompatibility genes and suggest an ancient origin of V-set domains.

This paper introduces CRISPR/Cas9-mediated gene knockin in Hydractinia symbiolongicarpus, enabling stable transgene integration and germline transmission for functional genomics studies.
