Plants produce electrical signals when their leaves are damaged. While some of the key molecules required for this process have been identified, the mechanism by which the electrical signal propagates has been unclear until now. The research team discovered that proteins released from damaged tissues travel long distances in the plant tissue to trigger the electrical signal. Farmer Laboratory - UNIL - Plants have a powerful warning system in case of attack, based on a sophisticated communication mode. In a study published in the journal "Cell", the group of Prof. Edward Farmer of the University of Lausanne details the mechanism of propagation of the electrical signal essential to this defense process . Leaves are extremely sensitive to damage. When one of them is damaged by a herbivore, an insect or a parasite, it reacts quickly by sending electrical signals to the other leaves in order to inform them of its 'health'.
