Embryonic expression of dachshund homologues in the head of P. tepidariorum. (A to E) Expression of Pt-dac1 during head development. The arrowhead in A to C points to expression at the lateral edge of the head lobes. The arrowhead in D and E points to expression in the primordia of the anterior lateral eyes. (F to J) Expression of Pt-dac2 during head development. Expression in the lateral eye primordia is denoted by white arrowheads in H to J. The black arrowhead in H denotes expression anterior to the labrum. All embryos are shown in frontal aspect. The developmental stage is indicated in each panel in the lower left corner.
