Expression pattern of the Cs-Ubx-1 and Cs-Ubx-2 genes. The anterior expression border of both Ubx genes is in the second opisthosomal segment (O2). The one of Cs-Ubx-1 (A) is at the anterior edge of O2, while the one of Cs-Ubx-2 is at posterior portion of O2 and corresponds to the parasegment boundary [15]. The opisthosomal limb primordia that will form the respiratory organs and spinnerets are visible on O2-O5. Abbreviations: L4: walking leg 4, O1-O6: opisthosomal segment 1–6.
