Erysimum cheiranthoides
Also called Treacle mustard, Wormseed mustard, Treacle Wallflower, Wallflower Mustard, Worm Seed Wallflower
Wormseed wallflower is a fast-growing annual mustard with bright yellow flowers, native to temperate Europe and Asia. It grows easily from seed in sunny, open ground and is often used as a research model plant.
Erysimum cheiranthoides, the treacle-mustard, wormseed wallflower, or wormseed mustard is a species of Erysimum native to most of central and northern Europe and northern and central Asia. Like other Erysimum species, E. cheiranthoides accumulates two major classes of defensive chemicals: glucosinolates and cardiac glycosides.
Erysimum cheiranthoides is native to temperate areas of Europe and Asia.
Because Erysimum is in the family Brassicaceae, it has been proposed that many of the genetic resources that already exist for Arabidopsis thaliana (an extensively studied model organism) can be used with Erysimum to aide in genetic analysis, making this genus particularly attractive for studying the cardenolide biosynthetic pathway. E. cheiranthoides itself is diploid and has a relatively small genome (~200 Mbp across 8 chromosomes), can be grown from seed to seed production as fast as 10 weeks, and performs well in a laboratory setting. The genome of E. cheiranthoides variety Elbtalaue has been sequenced. As E. cheiranthoides has many genetic similarities to A. thaliana, it is likely that techniques for genetically modifying A. thaliana and related research methods will also work for E. cheiranthoides. Mutated isolates of E. cheiranthoides with altered cardiac glycoside content have been identified.
