Summary of circular chromosome conformation capture (4C) interactomes. Circos plots illustrate the 4C interactome, transcription rate, and chromosomes with euchromatic and centromeric regions. Line color refers to the color of the viewpoint names at the periphery of the Circos plots. Only interactions with a P < 10-3 are plotted. (A) Trans- interactions; (B) cis interactions; (C) 4C interactome of viewpoint FIS2. Color code refers to significance levels. Gene density (blue circles) and transposable element density (purple circles) are indicated to illustrate the occurrence of heterochromatin and euchromatin. The region covered by the knob hk4s is highlighted with a transparent rectangle on the short arm of chromosome 4. Interaction values equal to ∑i(log2(number of reads in fragmenti)), where i stands for a fragment within a given window, are scaled to the viewpoint’s total library size.
