Plants respond to being wounded by increasing the production of proteinase-inhibitor genes, which in turn block the feeding of insects that caused the damage. O'Donnell et al. show (p. 1914) that the signals regulating expression of these genes include ethylene as well as jasmonates. Ethylene production is detectable shortly after wounding and well before changes in the transcription of the proteinase-inhibitor genes are detected.
