Résumé
The biosynthesis of (S)2-hydroxy-2-phenylethylglucosinolate was studied in Resela luteola L. Labeled compounds (¹⁴C and ¹⁵N) were administered to plant shoots and the incorporation of tracer into either the aglycone or glucosinolate was measured. l-2-Amino-4-phenylbutyric acid was more efficiently converted into (S)2-hydroxy-2-phenylethylglucosinolate than were the stereoisomers of 2-amino-4-hydroxy-4-phenylbutyric acid. The C-2 and amino nitrogen of these precursors were incorporated into the glucosinolate as a unit. The presence of 2-phenylethylglucosinolate in the plant was confirmed. Results of tracer studies supported the biosynthetic scheme: phenylalanine → → 3-benzylmalic acid → → 2-amino-4-phenylbutyric acid → → 2-phenylethylglucosinolate → 2-hydroxy-2-phenylethylglucosinolate.
