Figure 5

Embryonic expression patterns of Sp genes in Oncopeltus fasciatus. (a-c) Expression of the Sp1-4 representative after serosal closure (a), at early germband elongation (b), and at full germband elongation (c). (d, e) Expression of the Sp6-9 representative Of-Sp8/9 at full germband elongation (d) and mid germband retraction (e). The arrowhead and arrow in d denote expression in the brain and ventral nervous system, respectively. All embryos are oriented with anterior to the top. Abbreviations see Fig. 4. Additional abbreviations: hl, head lobe; an, antennal segment/appendage.
