Cloned(Commentary)

Cloned (Comment) Organism
CYP93G1 is placed under the control of the cauliflower mosaic virus 35S promoter and transformed into the Arabidopsis transparent testa6 (tt6) mutant. Transgenic expression of CYP93G1 in Arabidopsis thaliana results in the accumulation of different flavone O-glycosides, which are not naturally present in cruciferous plants Oryza sativa
