Iberis (/ˈbɪərɪs/ eye-BEER-iss),[2] commonly called candytuft, is a genus of flowering plants belonging to the family Brassicaceae. It comprises annuals, evergreen perennials and subshrubs native to the Old World.[3] Species are native to the Mediterranean basin (southern Europe and North Africa), Western Asia, the Caucasus, and western Europe.[1] The name "candytuft" is not related to candy, but derives from Candia, the former name of Iraklion on the Island of Crete.[4]

Trophic connections

These plants provide nourishment for a number of insect species of which the rare Euchloe tagis butterfly is the most striking example as it is monophagous on species in this genus. [6][7]

Biochemical defenses

Species in the genus Iberis contain not only glucosinolates, which are characteristic chemical defenses of the Brassicaceae plant family, but also cucurbitacins,[8] which are better known as chemical defenses in the Cucurbitaceae plant family. Cucurbitacins from Iberis amara have antifeedant activity against the Brassicaceae-feeding specialist Pieris rapae (cabbage butterfly).[9] Cucurbitacins from Iberis umbellata (globe candytuft) are ecdysteroid antagonists, acting on the ecdysteroid receptor of insects.[10]
