Kiwifruit ripening-related genes and transcription factors expression as affected by 1-MCP, O3 and exogenous ethylene. Gene expression of aminocyclopropane-1-carboxylic acid oxidase 1 (ACO1, a-e), ethylene receptor (ETR, f-j), expansin 2 (EXP2, k-o), geranylgeranyl diphosphate synthase (GGPS, p-t) and lipoxygenase 1 (LOX1, u-y) in kiwifruit ripened under ambient air or exogenous ethylene (ETH) at various ripening time points at 20 °C following 6 months of cold storage. Real-time RT-qPCR was used to analyse the relative mRNA abundance on three biological repeats per treatment. Vertical bars in figure plates represent the least significant difference (LSD, P = 0.05), which was used for comparisons of means between treatments (exposed or not to exogenous ethylene) and ripening time points
