Fig. 2

a The distribution characteristics of the compartments on the linear chromatin. The upper track shows the partitioning of A compartments (blue histogram) and B compartments (red histogram). The lower track shows chromatin interactions in Chr 1, Chr 14, and Chr 35 at 200 kb resolution. b The types of switched A/B compartments during muscle development of the two breeds. The outermost grey bars represent stable compartments and the pink bars represent switched compartments. c Proportion of chromatin transcriptionally active regions (TARs) in the genome in the breast muscle of adjacent periods. The pie chart divides chromatin into different types based on compartmental switching. The chromatin switched to TARs is the sum of common TARs and breed-specific TARs. d-e Two representative functional genes located in TARs during the neonatal and starter stages of two breeds, including ATAC1 and SQLE. The dashed line boxes indicate the chromosomal locations of the interested genes. The tracks show the compartment (top panels), ATAC-seq (middle panels), and gene expression (bottom panels) features at 100 kb resolution.
