Fig. 8: Volatile profile of Ple. Miss Joaquim ‘Agnes’ using GC-HRMS.

a Diagram illustrating the biosynthesis of unsaturated C9 aldehydes via two-step enzymatic degradation of linoleate derivatives. b Venn diagram showing the overlap between volatile compounds in flower and leaf of Ple. Miss Joaquim ‘Agnes’. c Table shows volatile compounds’ abundance by component class and their comparison between flower and leaf tissues. d Box plot showing the expression of CCD7 across the tissues of PMJ. The labellum and gynostemium of PMJ show enhanced activity of CCD7, the enzyme responsible for beta-ionone production. For each tissue, n = 3 biological independent samples were considered the center line show the medians and box limits indicating the 25th and 75th percentiles. Wilcoxon rank sum test was performed pairwise across tissue groups, and only statistically significant differences across means are reported in the plot.
