Simplified biosynthetic of isorhamnetin by (A) the shikimic and (B) the phenylpropanoid pathways. PAL: phenylalanine ammonia lyase, C4H: cinnamate 4-hydroxylase, 4CL: 4-coumaroyl-coenzyme A ligase, CHS: chalcone synthase, CHI: chalcone-flavanone isomerase, FNS: flavone synthase, F3D: flavanone 3-dioxygenase, FS: flavonol synthase, FMT: flavone 3′-O-methyltransferase.
