Figure 3

Expression patterns of Tt.dachshund, Tt.mPrx, and Tt.NK1. All images are oriented with anterior to the left. Panels (A-D) and (I-L) are lateral views. Panels (E, F) and (M, N) are blastoporal views. Panels (G, H) and (O, P) are ventral views. For detailed descriptions of expression patterns, see text. (A-H) Tt.dachshund expression in the archenteron walls at gastrula stages. Broad mesodermal expression at larval stages, along with additional domains in the pedicle lobe ectoderm (black and white arrows) and the dorsal eyespot (black arrowhead) and ventral ganglion (white arrowhead) regions of the apical lobe. (I-P) Tt. mPrx expression in the archenteron walls at gastrula stages. Expression in the lateral mesoderm at the boundary of the mantle and pedicle lobes in larval stages. (Q, R, U, V) Tt.NK1 expression in the archenteron walls (black arrow) and blastopore lip (black arrowhead) at gastrula stages. (S, T, W, X) Expression of Tt.NK1 in the pedicle mesoderm (black arrow) and posterior apical ectoderm (white arrowhead) at larval stages.
