Heterologous expression of Ginkgo biloba flavanone 3-hydroxylase acts as a key metabolic switch partitioning flavonoid metabolic flux in transgenic tobacco
{{output}}
GbF3H acts as a hierarchical switch that suppresses NtFLS1 but activates NtFLS2, thereby diverting flavonoid flux away from flavonols and toward isoflavonoids in transgenic tobacco. Flavanone 3-hydroxylase (F3H) is a key branch-point enzyme in the flavonoid bi... ...
