Phytochemistry Studies

Cardiac glycosides protect wormseed wallflower (Erysimum cheiranthoides) against some, but not all, glucosinolate-adapted herbivores.

Researchers studied how the evolution of a new defensive compound in a plant affects its interactions with herbivores. They identified enzymes involved in the production of the compound and found that it effectively defended against some, but not all, specialist herbivores. This research helps understand the chemical arms race between plants and insects.
