Validation of transcriptome data by qRT-PCR. Genes were selected based on gene enrichment analysis of the wounding stress (0.25 h) condition. Quantitative real-time PCR analysis was performed for 15 genes, and the values (least squares means) were fitted to a linear regression model. Both the x- and y-axes are shown in a log2 scale. Real-time PCR data was obtained from three independent experiments. Actin (Act2) was used as an internal control.
