To investigate the representation of genes among the five tissue types, hierarchical clustering of tissues, based on global gene expression and GO terms, was performed on 100 genes with the highest sum of all transcripts per million (TPM). The biological identity of the tissues was clearly reflected in the analysis by hierarchical clustering of the RNA‐Seq‐based transcriptome (Figure 3; Table S9). Predicted genes showed substantial variation in their expression over tissues, reflecting tissue‐specific biological activities. For instance, in leaf and petiole tissue GO‐based clusters G1 and G2 were enriched and genes‐encoding proteins involved in photosynthesis, binding and chloroplast thylakoid membranes were over‐represented consistent with the specialized biological function of these tissues. Likewise, the root transcriptome profile showed enriched expression for stress and defence responses with genes encoding for cysteine‐type endopeptidase inhibitor activity. However, the G3 cluster indicates commonalities in the transcriptome of all above ground vegetative tissue types and showed enrichments for translational and structural ribosomal pathways.
