One plant produced sesquiterpene, (E)‐β‐farnesene (EBF), has been considered a potential defense against aphids, since its emission by plants causes aphids to drop off the plant or depart from the feeding site.

For many aphids, EBF is the principal constituent of the aphid alarm pheromone, and the constitutive production of EBF by plants could hold promise in the control of specific aphid pests

The hydrolyzing enzyme, myrosinase (a thioglucosidase), is stored in different cells than its substrates. While myrosinase-containing cells are mostly glucosinolate-free, the so-called sulfur-rich cells (or S-cells) contain high concentrations of glucosinolates.
