Fig. 1. Distribution of TADs across the rice genome.

a Contact maps showing TADs across a section of rice chromosome 1. TADs identified as regions of high chromatin interactions by Armatus are outlined by black triangles. The remaining regions are inter-TADs. Tracks below Hi-C data present selected epigenetic modifications in TAD and inter-TAD regions. b Overlap between TADs called by Armatus in this study and those identified by Liu et al.⁷ Both sets of TADs overlap much more than it would be expected by chance alone. Green line—observed overlap, grey line—mean of simulated overlap, red line—significance threshold. TADs: n = 4599, inter-TADs: n = 3346.
