a n-HomoMet-derived and other aliphatic GSLs as specified in Table 5. Searched for but not detected (all three species): The typical Barbarea seed isoferuloyl derivatives (6’iF PE, 6’iF IM, 6’iF BAR, 6’iF EBAR), as well as hypothetic isoferuloyl and benzoyl derivatives of other dominating GSLs. Searched for but not detected in N. officinale: BZ, 4hBZ, 4hEBAR.Searched for but not detected in P. virginica and R. sylvestris: all substituted IMs: 4hIM, 1moIM, 4moIM, 1,4moIM. Searched for and not detected in P. virginica: BZ, 4hBAR, hydroxy-methoxy derivatives 4moEBAR and 3/4 hmoEBAR (“ x1 ”). GSL data with an asterisk indicate lack of MS2 confirmation of analyte identity due to low level.
b Confirmed by UHPLC-QToF (Supplementary Fig. S4) and quantified tentatively based on N 3 samples.
