Metabolite accumulation and expression of genes in the two putative dhurrin turnover pathways. The transcript boxes are simplified versions of the earlier figures: GST1 (Fig. 7b), GST2 (Fig. 7c), NIT4A/B2 (Fig. 5), UGT1 (Fig. 10b), UGT2 (Fig. 10d) and nitrilase/amidase (Fig. 8). The dhurrin acid and amide can in principle be formed via two different routes: from dhurrin or directly from pOHMn, *which then requires an additional glycosylation step in order to get the dhurrin acid and amide
