A Phylogeny of C3OMT genes among 13 plant species, including Brachypodium distachyon, Dioscorea rotundata, Phalaenopsis aphrodite, Phoenix dactylifera, Acorus calamus, Curcuma longa, Arabidopsis thaliana, Solanum tuberosum, M. acuminate, M. balbisiana, O. sativa, Z. officinale, and A. trichopoda. Genes from monocots and dicots are denoted by different colored circles. The C3OMT genes were grouped into 3 clades/subfamilies, each of which is shown in a different color. The C3OMT genes in ginger are marked with an asterisk. The unique C3OMT genes in ginger are indicated by red asterisks. B Coexpression network connecting structural genes in gingerol biosynthesis with transcription factors. The color-filled hexagons represent the structural genes associated with gingerol biosynthesis that were highly (red) or lowly (blue) expressed in ginger rhizomes. The size of the hexagon represents the FPKM value ratio of each gene between Rh1 and Rh5. Expression correlations between TFs (colored solid circles) and gingerol-related genes (colored solid hexagons) are shown with colored lines (Pearson’s correlation test, P < 0.05)
