Answer
Infected cells send hormonal signals to other cells in the plant, causing a systemic acquired resistance response. The hormone used is salicylic acid, which is stimulated by receptor binding in general and specific immunity. Salicylic acid can also be converted to a gaseous derivative to extend the signal to nearby plants as well.
