From: Hox gene expression during development of the phoronid Phoronopsis harmeri
Whole-mount in situ hybridization of each Hox gene during larval development of Phoronopsis harmeri. Name of each hybridized gene is shown on the left, while developmental stages are indicated on the top. All the stages are presented with anterior to the top. Larvae on panels a, c, e, g and i are in dorso-ventral view, whereas larvae on panels b, d, f, h and j in lateral view with ventral to the left. The black line indicates the onset of expression of each Hox gene based on in situ hybridization data. Black arrowheads indicate expression in the metasomal sac, blue arrowheads expression in the protonephridia, red arrowheads expression in the mesoderm, green arrowheads expression in the telotroch and magenta arrowheads expression in the digestive system. The detailed expression patterns are described in the text. Photographs are not to scale
