ABSTRACT
Biosynthesis of steroidal plant hormones, brassinosteroids, was studied using the cell culture system of Catharanthus roseus. Feeding labeled compounds of possible intermediates to the cultured cells, followed by analyzing the metabolites by gas chromatography-mass spectrometry disclosed the pathways from a plant sterol, campesterol, to brassinolide. There are two pathways, named the early C6-oxidation pathway and late C6-oxidation pathway, both of which would be operating in a wide variety of plants. Recent findings of brassinosteroid-deficient mutants of Arabidopsis and the garden pea by several groups, and the possible blocked steps of the mutants in the biosynthetic pathways are also introduced.
