Figure 1

Expression of Nvi-ParaHox genes in the prostomium. White asterisks mark the site of the stomodeum, which is under the prototroch in the hyposphere. (a-c) Embryos are viewed from the animal pole. Nvi-Gsh is expressed in early stages in bilaterally symmetrical cells of the episphere. White arrows mark Nvi-Gsh expression in the stomodeum. (d-f) During the nectochaete stages Nvi-Gsh is expressed in a small group of cells at the ventral (d, e) and the dorsal (f) sides of the prostomium. (g, h) Expression of Nvi-Xlox. (g) View from the animal pole. Early expression is very weak and occurs transiently in the lateral areas of the episphere. (h) At the nectochaete stage Nvi-Xlox is expressed in a pair of lobes in the cerebral ganglion.
