For example, scientists could engineer high-yield plants by cranking up the activity of the morphine synthesis genes, Larkin says. Scientists could also block morphine production with engineered ...

Scientists inserted an orange pigment into yeasts, right, to help find the missing enzyme needed to complete the synthesis of morphine in the microorganism. Making morphine — or heroin,* for ...

Furthermore, conolidine had no effect on the locomotor activity of mice, while morphine did. The authors have not yet determined conolidine’s mechanism of action. Tarselli’s synthesis of ...

Scientists inserted an orange pigment into yeasts (right) to help find the missing enzyme needed to complete the synthesis of morphine in the microorganism. That day is approaching faster than ...
