DmVav cannot connect Rac1 activation to the stimulation of the JNK pathway. Embryos wild type (wt, A) or expressing the indicated DmRac1 (B) and DmVav (C) proteins in segmental stripes of the embryonic ectoderm were subjected to whole mount in situ hybridization using an anti-sense probe to the JNK target dpp. After development of signals, embryos were mounted and photographed. The arrow indicates a stripe positive for dpp expression (B).
