Tunneling behavior of various genotypes examined in these studies.
Images of cleaned agarose plates from tunneling assays for key genotypes are shown. Tunneling was quantitated using Image J. Five control genotypes (panels (d)-(h)) show robust tunneling. lov91Y-Gal4 > RNAi larvae show comparable tunneling activity (panel (c)) but tunneling is completely absent for cut(ue)-Gal4 > RNAi and btl-Gal4 > RNAi larvae (panels (a) and (b). lov91Y-Gal4 /lov def larvae show limited tunneling behavior (panel (i)).
