The proposed model of aboveground to belowground defense signaling in the maize inbred Mp708. Caterpillar feeding in the whorl (1) sends a currently unidentified signal through the vascular system to the roots, where Mir1-CP and possibly other defense gene products accumulate (2) and protect plants against root feeding herbivores. The roots (3) serve as a potential source of Mir1-CP that can be translocated back to the whorl in response to caterpillar feeding. Drawing by Nick Sloff.
