Genome-wide searches and molecular analyses highlight the unique evolutionary path of flavone synthase I (FNSI) in Apiaceae
{{output}}
Flavone synthase is a key enzyme for flavone biosynthesis and is encoded by two gene families: flavone synthase I (FNSI) and flavone synthase II (FNSII). FNSII is widely distributed in plants, while FNSI has been reported in rice (Oryza sativa) and seven speci... ...
