Transcriptome Profiling across Five Tissues of Giant Panda

Figure 1

Overview of all genes expressed level in the giant panda. (a) Statistical histogram of the number of genes expressed in each tissue using the R language function barplot. (b) Violin plot generated by the ggplot2 R package based on FPKM value of all genes in each tissue. The ordinate represents log10(FPKM+1). Each region of violin plot corresponds to five statistics (top-down, maximum, upper quartile, median, lower quartile, and minimum). The width of each violin represents the number of genes under that expression. (c) Hierarchical clustering heatmap of all expressed genes based on the normalized FPKM values. It generated by the pheatmap R package and the red-blue spectrum represents the normalized FPKM values. (d) Principal component analysis based on the FPKM value of all expressed genes using the ggplot2 R package.
