Figures & data
Figure 1 Within-plant signaling by volatiles. Volatiles (shadowed area) fill the aerial space around an herbivore-damaged emitter leaf(E, marked grey) and can rapidly induce spatially neighboring receiver leaves (R), which might anatomically be very distant. Volatile-mediated signaling (bold arrow) that functions via green leaf volatiles such as the displayed (Z)-3-hexenyl acetate thus allows much shorter signaling ways from emitter to receiver leaf that molecules such as jasmonic acid (JA) which move within the plant veins (scattered arrow).
