Fig. 5. Secondary modifications in glucosinolate (GSL) biosynthesis. (A) Biosynthesis of secondary modifications in Trp-derived GSLs ("indole GSLs") in Arabidopsis thaliana (Pfalz et al. 2011, 2016). (B) Biosynthesis of a more complex indole GSL is still unknown. (C) Two possible biosyntheses of p-hydroxybenzyl GSL (23), the relative importance of which in nature is not known. In the current paper, bold and square brackets around GSL numbers indicate incomplete MS and NMRdocumentation for their existence (Section 2).
