Figure 1

On herbivore attack, levels of the plant hormone jasmonate increase, triggering defence responses. Mousavi et al.1 show that leaf injury, caused by herbivory or mechanical wounding, induces the transmission of electrical signals that are generated by the activity of glutamate-receptor-like (GLR) ion channels. These signals induce the formation of jasmonate at local and distant sites in the plant.
