Abstract

Systemin is one of the few peptide signals currently shown to exist in plants. A well known function of the peptide is in the regulation of wound-responsive gene expression in the model system of tomato. We have recently discovered a new function of systemin. This is its ability to induce ethylene. Surprisingly, the structural requirements of this activity clearly distinguish it from other known activities of the peptide. The aim of the research is to understand this new function in detail, through: (1) defining residues of in systemin required for its activity; (2) identifying binding proteins which may function in transduction; and (3) identifying the site(s) of action of the peptide through targeted transient expression in planta. This foundation is essential if we are to understand the full implication of systemin actions in wound and pathogen signalling.
