Aphid resistance segregates independently of cardiac glycoside and glucosinolate content in an Erysimum cheiranthoides (wormseed wallflower) F2 population.

Summary

Scientists studied two wormseed wallflower plant isolates and found differences in their defensive metabolites and resistance to aphids. Genetic factors affect metabolite production, but other unknown processes contribute to aphid resistance.

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

Summary

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.

Reversing the escape from herbivory: Knockout of cardiac glycoside biosynthesis in wormseed wallflower ( Erysimum cheiranthoides L., Brassicaceae).

Summary

Wallflowers produce glucosinolates and cardiac glycosides to defend against herbivores. Knocking out enzymes involved in cardiac glycoside biosynthesis makes them susceptible to herbivory. Specialist herbivores are unable to feed on wallflowers without cardiac glycosides.
