Utilisation of the MVA pathway to produce elevated levels of the sesquiterpene α-copaene in potato tubers

► We describe the first report of metabolic engineering of sesquiterpenes in potato. ► Transgene expression level and α-copaene abundance positively correlate. ► Flavour metabolite correlations with taste panel assessments are reported. ► Sensory analysis suggests that α-copaene is not a major component of potato flavour.
