Figure 8From: Molecular characterization and embryonic origin of the eyes in the common house spider Parasteatoda tepidariorum 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.Back to article page
