Expression of Aurelia aurita otx and gata orthologs during strobilation and in free ephyrae. a–c Aa-otx1 is expressed in the oral ectoderm of each individual ephyral disc (a), before the otx signal gradually fades in later stages. Aa-otx1 remains specifically expressed in individual cells at the oral ectoderm of the free ephyra (b) and in distinct cell clusters in the rhopalia (c). Aa-gata (d–i) is weakly expressed in the aboral ectoderm of each ephyral disc during strobilation (d, arrowheads). In the free ephyra, it is broadly expressed in the ecto-and endoderm (e, f) and in specific cells lining the mouth of the ephyra, presumably neurons (h, i). Colours in schematics represent Aa-gata (green) and Aa-otx (red). For clarity, broad Aa-gata expression and single cells of Aa-otx in the ephyral ectoderm are not represented in (h)
