Figure 4. Gain and loss of PPP genes in Drosophilidae.

Figure 4

The basic PPP set of insects is in a black box. Gained genes are in blue and lost genes are in red boxes. The broken line indicates that the Pp2B-14D gene was gained in the Diptera. The family tree of the 12 Drosophila species with a mutational clock is presented in Figure S1A.
