Toll signalling acts downstream of JNK in eye development. (a–o) Light micrographs showing Drosophila adult eyes. The small and rough eye phenotype resulting from ectopic expression of dTAK1 (a) or HepCA (f) is suppressed partially by RNAi-mediated knocking-down of bsk (c and h), pelle (d and i) or dorsal (e and j), but not of LacZ (b and g). The rough eye phenotype produced by GMR>Bsk (k) is obviously suppressed by RNAi-mediated inactivation of Toll pathway components: pelle, dorsal and Dif (m–o), but not by the expression of GFP (l). (p) A diagram for the key components of the Egr–JNK pathway. See the electronic supplementary material for detailed genotypes.
