Overview of transcriptome of peach fruit at given time points during the ethylene treatments. (a) Number of differentially expressed genes (DEGs) identified by pairwise comparison between ethylene treatment and control at each time point (p < 0.05). Up, up-regulation; Down, down-regulation. (b) Hierarchy clustering of DEGs (p < 0.05, and log₂foldchange > 1) across the different samples. The rows in the heatmap represent genes, and the columns indicate samples. The colors of heatmap cells indicate scaled expression level of genes (log₂ FPKM) across different samples. The color gradient, ranging from green, through black, to red represents low, middle and high values of gene expression. The sampling points beginning with the letter C or E indicate those belong to control and ethylene treatments, respectively. FPKM, fragments per kilobase of transcript per million fragments mapped.
