| Abstract: | Effects of elicitors (mannan,  -1,3-glucan, and ancymidol) on the activity of several key enzymes participating in lignan biosynthesis were studied in Linum austriacum L. cell cultures. The activities of L-phenylalanine ammonia-lyase, polyphenoloxydase, tyrosine ammonia-lyase, soluble phenoloxidase, and membrane-bound and soluble oxidases were assayed. The elicitors under study affected various steps in the metabolic pathway of lignan biosynthesis. Elevated enzyme activity accompanied an elicitor-enhanced synthesis of podophyllotoxins and peltatins. |
