Functional communities of chromatin interactions in chromatin interaction network (ChINs). a All the ChINs identified in immature ear. Here only showed the ChINs with more than 30 nodes. b Enrichment of gene ontology (GO) terms in top 50 ChINs in immature ear and shoot. Only significant GO terms (false discovery rate (FDR) <0.05) are presented in the left panel. Enrichment of GO terms is represented as scaled proportions of the observed number of hits in a ChIN component (orange) vs. the expected number of hits in the genome (blue). The right panel showed a ChIN in immature ear, where all genes were enriched in cell function (GO term). c The ChIN for ZmASR1 (in red) in shoot. The arc map in left bottom showed the region span of all chromatin interactions in this ChIN on genome. d The ChIN for Dwarf8 (in pink), which regulates plant height and flowering time, in immature ear. There were other nine genes (GIF1, UB2, bHLH27, bHLH212, DOF27, DOF28, SBP16, SBP17, and Zm34359; in red) potentially associated with flowering in this ChIN. Circos map in the left bottom showed the region span of all chromatin interactions in this ChIN. Chromatin interactions with distance longer than 1 Mb are highlighted by orange arcs, others in blue. Ellipses in blue and red indicated proximal PET peaks (P) and distal PET peaks (D), respectively, in ChIA-PET datasets. P–P, P–D, and D–D interaction are presented in blue, green, and red edges in network. Source Data of Fig. 7d are provided as a Source Data file
