  Fig. 2. Xenopus AbdB-type Hox genes have specific domain of expression along the anteroposterior axis. Black and white arrows indicate the anterior limit of gene expression in the CNS and the paraxial mesoderm, respectively. Black arrowheads indicate anterior limits in the kidney. First column: expression pattern at stage 20 with the exception of U, which is a stage 26 embryo. Second column: stage 32. Third column: stage 39. Fourth column: detail of expression in the tail bud at stage 32. (A–D) Xhoxa9; (E–H) Xhoxd9; (I–L) Xhoxd10; (M–P) Xhoxa11; (Q–V) Xhoxc12; (U–X) Xhoxa13, arrow in W points to the expression in the most distal part of the hindgut.

  Fig. 4. Xenopus AbdB-type Hox gene expression in the developing gut. Expression is confined to the prospective large intestine. It is mesodermal in all cases except Xhoxa13, where it is both endodermal and mesodermal (see insets P′ and T′). pr, proctodeum.
