The expression of transcripts putatively involved in the biosynthesis of terpenes and sterols. The mRNA expression of genes putatively involved in the biosynthesis of volatile monoterpenes (A), tri-terpenoids and sterols (B), di- and tetra-terpenoids (C), as determined using RT-qPCR, and a schematic representation of this pathway. IPP: Isopentenyl diphosphate; GPP: Geranyl diphosphate; GES: geraniol synthase; LS: Limonene synthase; FPP: Farnesyl diphosphate; FPPS: FPP synthase; GGPP: Geranyl geranyl pyrophosphate; GGPS: GGPP synthase; SQS: Squalene synthase; LUPS: Lupeol synthase. The relative mRNA levels are expressed as ΔΔCt. Bars = ±SE, n = 3. Different letters indicate significant differences between samples as determined using analysis of variance (Bonferroni’s post hoc tests, P < 0.05).
