Abstract:
When plants are wounded, a long-distance signal is produced that activates the wound response in unwounded leaves. Recent work by Gregg Howe's group suggests that jasmonic acid is the long-distance wound signal. Previously, many data indicated that the signaling peptide systemin might function as the systemic wound signal. According to the new data, systemin is crucial for the production of the systemic wound signal in the wounded leaf, but might not travel long distances.
