Fig. 6. The genetic interaction partners of DAAM. Trachea dissected out from third instar DAAM^Ex1 mutant larvae display a moderate cuticle phenotype (A), which is strongly enhanced by removal of one copy of RhoA (B), Tec29 (C) and Src42A (D). The DAAM trachea phenotypes are already exhibited in first instar larvae (E,F). Homozygous mutant Tec29 (G) and Src42A (H) first instar larvae display a moderately strong taenidial phenotype similar to DAAM^Ex1 (compare G and H with E). Consistent with this, apical actin organization is partly impaired in Tec29 (I) and Src42A (J) mutant embryonic tracheal tubes (compare I and J with Fig. 4E). Scale bars: 50 µm in A-H; 10 µm in I,J.
