Terpenoid pathway analysis. (A) Schematic diagram of terpenoid pathways. Abbreviations: MEP: methylerythritol phosphate; MVA: mevalonic acid; G3P: glyceraldehyde 3-phosphate; DXP: 1-deoxy-D-xylulose-5-phosphate; DXS: DXP synthase; DXR: DXP reductoisomerase; CMS: 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase; CMK: 4-(cytidine 5′-diphospho)-2-C-methyl-D-erythritol kinase; MCS: 2-C-methyl-D-erythritol 2, 4-cyclodiphosphate synthase; HDS: 4-hydroxy-3-methylbut-2-en-1-yl diphosphate synthase; HDR: HMBPP reductase; IPP: isopentenyl diphosphate; IDI: isopentenyl pyrophosphate isomerase; DMAPP: dimethylallyl diphosphate; FPP: farnesyl diphosphate; GPP: geranyl pyrophosphate; GGPP: geranylgeranyl pyrophosphate; AACT: acetyl-CoA acetyltransferase; HMGS: HMG-CoA synthase; HMGR: HMG-CoA reductase; PMK: phosphomevalonate kinase; MPDC: mevalonate diphosphate decarboxylase; NES1: nerolidol synthase 1; CCD: carotenoid cleavage dioxygenases; (B) Transcript level of biosynthetic genes related to terpenoid pathways in the fruit of ‘Benihoppe’ (WT) and ‘Xiaobai’ (mut) at four developmental stages. Darker red indicates a higher expression level, whereas darker blue indicates a lower expression level.
