Figure 3

Cupiennius salei embryos stained with Hox gene probes. (A and B) Staining with LAB. The anterior border of staining is within the pedipalpal segment (A), and the posterior border is within the last leg segment (B). The chelicerae are completely free of staining. (C) Staining with DFD. All four leg segments are stained. (D–E) Staining with ANTP. Staining is evident directly adjacent to the last leg-bearing segment but covers the posterior half of L4 (E). (F) Staining with UBX-1. The anterior border of expression is seen within abdominal segment 1. (G) Staining with UBX-2. Expression begins in abdominal segment 2. (H) Staining with ABD-A. Expression begins within abdominal segment 3. (I and J) Close comparison of expression borders of UBX-1 (I) and UBX-2 (J) and immunostaining with the broadly cross-reacting antibody FP6.87 against UBX and ABD-A homeoboxes (24) in K; the staining of the leg (L4) is an artifact of the labeling procedure used in this case. Abbreviations as in Fig. 2.
