Volatile evolution patterns in the ‘Granada’ (Gra) and ‘MxR_01’ time-course series. A) The heatmap and cluster analysis of volatile compounds in the two time-course series (three replicates per stage are shown). The clusters observed (1–13) are indicated in the dendrogram. Data are expressed as log2 of a ratio (sample/common reference). Red boxes indicate those groups of compounds that increase (I) or decrease (II) during ripening. B) The evolution patterns for volatiles that change during ripening (I and II). An average profile of all the members of each cluster is shown. For each maturity stage (S1 to S4) and shelf-life response (S4+SL), the mean of the samples (n=3) is shown. Data are expressed as fold changes in relation to S1 (of each genotype) on the log2 scale. The positive region of the y axis is used for values higher than those of S1, while the negative region is for values that are lower than those of S1.
