Herbivores, and particularly chewing insects, cause substantial damage to the plant. In addition to lost tissue, there are great concerns of pathogen invasion and water loss at the site of the attack. One of the plant's defense strategies is the formation of wound periderm at the boundaries of the invaded or damaged region to isolate it from non-wounded healthy tissue. The development of wound periderm following insect feeding has never been specifically examined; although studies of herbivory and wound signaling have indicated extensive overlap in the respective sets of induced genes. © 2008 Springer Science+Business Media B.V.
