Response of the ‘Granada’ and ‘MxR_01’ genotypes to shelf-life ripening. A) A principal component analysis of the volatile compounds (left) and the gene expression (right) data sets. The first two principal components are shown (PC1 and PC2) for each analysis. Three replicates per genotype and treatment are shown. The red dotted circles indicate the genotype of the samples. B) Venn diagram of volatiles (left) and genes (right) that change significantly (p<0.05 for the volatile data, and FDR and a q-value of <0.05 for the gene expression data) after shelf-life ripening. Red and blue arrows indicate that the volatile or gene expression increase or decrease, respectively, after treatment. For volatiles, the fold change is indicated in parentheses below each one. For the three compounds that change in both genotypes, the fold change for ‘Granada’ is indicated on the left, while that for ‘MxR_01’ is on the right. For genes, the number of genes increasing or decreasing after treatment is indicated.
