Expression profiles of RsHSP70 genes in response to abiotic stress treatments. A Heatmap of differential expression of RsHSP70 genes in response to heat, drought, cd, salt and chilling stress. The color scale of heatmap is based on the log2-transformed FPKM values after the addition of a pseudocount of 0.01 between experimental and control tissues are shown. B Expression profiles of selected genes under heat, drought, cd, salt and chilling stresses from RNA-seq data and qPCR analysis. Correlation (R.2 = 0.7383–0.9295, P < 0.05) between RNA-seq data and qPCR results. Each bar shows the mean ± SE of the triplicate assay. Different letters indicate significant differences among treatments (P < 0.05, ANOVA)
