Venn diagrams illustrating co-regulated functional categories (MapMan and metal homeostasis categories) in the eight pairwise comparisons of transcriptome data. (A, B) Venn diagrams summarizing co-regulation data of enriched categories in pairwise comparisons of (A) root and (B) leaf transcriptome data. Each circle represents the pairwise comparison indicated. The numbers indicate the respective categories that were found enriched (see C, D). If categories were enriched in more than one comparison the respective number is found in the overlap region of the circles. (C, D) Designation of categories that were found enriched in (C) root comparisons and (D) leaf comparisons. Red coloured numbers indicate induced categories, green coloured numbers indicate repressed categories.
