Negative feedback by  dMK2  on  dERK/rolled  in ectopic wing vein development. (A, B) Representative ectopic vein patterns (black arrows) in control (a) and transgenic lines (b,c); percentages of flies with ectopic wing veins in different genetic contexts (indicated below graph; B); #: sd::Gal4 driver-induced ectopic veins nearby vein 2 (l2; white arrow head compare A), were not scored; *: significantly different from corresponding genotype without dMK2-LOF (z-test; P < 0.001).
