Plants know where it hurts: root and shoot jasmonic acid induction elicit differential responses in Brassica oleracea.
Plants respond to herbivore attack by rapidly inducing defenses that are mainly regulated by jasmonic acid (JA).Due to the systemic nature of induced defenses, attack by root herbivores can also result in a shoot response and vice versa, causing interactions between above- and belowground herbivores.However, little is known about the molecular mech
