malfunction
suppression of CYP82Y1 using virus-induced gene silencing causes a significant reduction in the levels of noscapine, narcotoline, and a putative downstream secoberbine intermediate and also results in increased accumulation of the upstream pathway intermediates scoulerine, tetrahydrocolumbamine, canadine, and N-methylcanadine
