Figure 9.15

Gradient of Caudal protein in the syncitial blastoderm of a wild-type Drosophila embryo. The protein (stained darkly) enters the nuclei and helps specify posterior fates. Compare with the complementary gradient of Bicoid protein in Figure 9.13. (From Macdonald and Struhl 1986; photograph courtesy of the authors.)
