Figure 2

Expression patterns of Tt.twist and Tt.GATA456. 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.twist expression throughout the archenteron wall at gastrula stages and in the anterior and chaetal sac mesoderm (black arrows) in larval stages. (A, E) The location of the blastopore in the radial gastrula stage is denoted by an asterisk. (I-P) Tt.GATA456 expression in the archenteron roof and walls at gastrula stages. Expression in the endoderm, pedicle mesoderm (black arrowheads), and chaetal sac mesoderm (black arrows) in larval stages. Scale bars are 50 μm in length.
