Plant Responses to Wounding

Plants react to mechanical damage by activating a set of wound-responsive genes, whose function is devoted to plant healing and prevention of subsequent pest and pathogen attacks. A wound-signalling cascade initiated at the site of injury is responsible for gene activation in local and systemic tissues.

Keywords: herbivory; jasmonic acid; wound-induced genes; wound signalling

Figure 1. Wound signalling networks in (a) potato, and (b) Arabidopsis thaliana. The molecular components involved in gene activation upon wounding, and their connections in both local and systemic leaves, are depicted. ABA, abscisic acid;  C2H4, ethylene; JA, jasmonic acid; OGAs, oligosaccharides. Arrows represent a positive interaction, a blunt-ended line indicates repression. Those genes that are activated are encircled: PIN, proteinase inhibitors; local and systemic genes, those whose expression is restricted to damaged and nondamaged tissues, respectively (see text for further explanation).
