Physical and chemical signals and their action in systemic responses of plants to local wounding
Original language description
Wounding, caused either by physical injury or by herbivore or insect attack, is one of the most severe plant stresses. Higher plants respond to such stress by initiating various defence-related processes, which include accumulation of defence-related proteins, gene expression, stomata movements and changes in respiration and photosynthesis. These processes take place locally, i.e. in the wounded leaf, but many defence responses were detected also in undamaged leaves distal to the site of wounding (systemic response). This finding indicates that a signal moves from the injured tissue to the distant untreated parts of the plant, where it triggers systemic response. Several kinds of chemical and physical signals have been identified in plants responding to local stress. Despite intensive research, there are still many controversial questions about the origin of these long-distance moving signals, their interaction and connection to systemic defence responses. In the following chapter, the
