Geographic and evolutionary diversification of glucosinolates among near relatives of Arabidopsis thaliana (Brassicaceae)

Glucosinolates are defensive, secondary metabolites that display both intra- and interspecific variation in the order Brassicales. As such, glucosinolate physiology has provided an opportunity to study the geographical, organismal, and genetic processes influencing the evolution of plant defenses at a macroevolutionary scale.
