TI - Metabolic engineering of the indole pathway in Catharanthus roseus hairy roots and increased accumulation of tryptamine and serpentine N2 - Transgenic hairy roots of Catharanthus roseus were established with glucocorticoid inducible tryptophan decarboxylase (TDC)expression alone or in combination with inducible expression of a feedback-resistant anthranilate synthase alpha subunit (AS)from Arabidopsis. Northern blot analysis confirmed transcription of the anthranilate synthase gene upon induction in the double line (TDC+AS)and in vitro enzyme assays confirmed increased resistance to feedback inhibition by tryptophan. In TDC enzyme assays, increases of 48 UR - https://drive.google.com/file/d/1Ok9zVgwEM_Av9GFpvrSelcnNJmFWVZib/view?usp=drivesdk ER -
