A based gene expression (RNA-seq) transcriptional atlas generated for the major organs of C. draco. a Venn diagram of the preferentially expressed unigenes in which solely those consider to be organ-specific and ubiquitous are represented. b Principal component analysis (PCA) of global transcriptional profiles. c Hierarchical clustering (HC) based on FPKM values calculated for C. draco unigenes preferentially expressed in some of the major organs analysed (leaves, fruits, stems, roots, inflorescences, and flowers). The dark blue represents higher expression values while the lowest values are shown in white
