Biosynthetic pathway of steroidal glycoalkaloids. Levels of detectable metabolites are expressed as fold/ISTD (Internal Standard: formononetin) in parental lines male P1 “(67/3)”, female P2 (“305E40”), and the F1 progeny. Metabolites marked in red have been identified by the untargeted analysis, in blue by the targeted one.
