Never-before-seen plant metabolites discovered




Purdue University researchers have captured evolution in action through the discovery of a new set of metabolites synthesized by Arabidopsis plants, according to research findings published this week in the journal Science.

Clint Chapple, distinguished professor of biochemistry; former Purdue graduate student Jing-Ke Weng; current Purdue graduate student Yi Li; and Huaping Mo, associate director of the Purdue Interdepartmental NMR Facility, were studying how new metabolic pathways evolve in plants when they discovered the metabolites, which they are calling arabidopyrones. Many different metabolites are used by plants for defense, pigmentation and to attract pollinators, while others are used by humans as pharmaceuticals and flavorings.
