Tissue-specific chromatin interactions in immature ear and shoot. a The heat map of fragments per kilobase of transcript per million (FPKM) value (left panel) and chromatin interaction (right panel) of all genes in immature ear and shoot. b The heat map of chromatin interactions of immature ear-specific expressed genes (p = 0.006, two-sided t test), common genes, and shoot-specific expressed genes (p = 0.002, two-sided t test) in immature ear and shoot, respectively. c An example of immature ear-specific chromatin interaction. FEA4 gene (highlighted in dark green) interacted with a distantly located (∼17 kb) distal PET peaks (D) (highlighted in yellow) in immature ear. In contrast, the FEA4 gene in shoot was not expressed and had no interaction with that D. d An example of shoot-specific chromatin interaction. PSBS1 gene (highlighted in dark green) interacted with a distantly located (∼58 kb) D (highlighted in yellow) in shoot. In contrast, the PSBS1 gene in immature ear was not expressed and had no interaction with that D. The green rectangle represents the corresponding gene. The blue and orange rectangles indicate P and D, respectively
