Abstract
In the course of investigations on brassinosteroid (BS) biosynthetic and metabolic pathways in plants, an approach using HPLC/APCI-MS analysis of underivatized BS for their identification in plant material has been developed. Its application to root-callus suspension cultures of Arabidopsis thaliana led to the first identification of 3-epibrassinolide as natural brassinosteroid.
