Fig. 3. Genetic interactions between Src42A and shg/arm. Anterior is leftwards in A-J. (A-C) Enhancement of the rough eye phenotype of sev-Src42A[KR]/+ flies (A) by shg^E(7A-1) (B) and shg^R64a (C). (D,E) Lateral views of stage 13 embryos of wild-type (D) and shg^E(7A-1) (E) stained for E-cad, showing significant E-cad-signal reduction in shg^E(7A-1). (F-J) Dorsal views of stage 15 embryos stained for Fas3, indicating dorsal open phenotype in double mutants. (K-N) Thorax-cleft phenotypes. Classification except for class 4 is based on Tateno et al. (Tateno et al., 2000). (O) Numerical data show that thorax-cleft phenotypes of Src42A^6-1 are enhanced by the introduction of a shg mutation, shg^g317.
