From: Hox gene expression during development of the phoronid Phoronopsis harmeri
Expression of head-specific genes in early larva (a–e, h, i, n–p, v, w) and 8-tentacle stage actinotrocha (f, g, j–m, q–u, x, y) of Phoronopsis harmeri and comparison of expression of head-specific and Hox genes in both larval stages (z). For each panel the name of hybridized gene is shown in the white box above micrographs. Entire larvae in the dorso–ventral (a, d, f, h, j, n, o, q, v, x) and lateral (b, c, e, g, i, k, p, r, w, y) views. Details of expression in 8-tentacle stage larvae in oral hood and anterior body region (l), hood musculature (m), apical organ, preoral coelom and rim of the hood (s) and tips of the tentacles (t, u). Black arrowheads point to the particular expression domains (see text for details), while asterisks indicate unspecific background staining. Scalebars 25 μm
