Biosynthetic routes leading to isoprenoids in Arabidopsis cell; the involvement of the genescis‐prenyltransferase 3 and putative role of α/β‐hydrolase is indicated. Depicted are seven metabolites analysed in this study. Two pathways, the mevalonate (MVA) and methylerythritol phosphate (MEP) pathways, are generating IPP in parallel, both contributing to particular isoprenoids (Akhtar et al., 2017; Hemmerlin et al., 2012; Jozwiak et al., 2017). Blue arrows illustrate the exchange of intermediates between the MVA and MEP pathways. DMAPP, dimethylallyl diphosphate; FPP, farnesyl diphosphate; GPP, geranyl diphosphate; GGPP, geranylgeranyl diphosphate; IPP, isopentenyl diphosphate [Color figure can be viewed at wileyonlinelibrary.com]
