Correlation of chromatin 3D structure and gene expression under nitrogen deprivation in N. oceanica. A Comparison of the number of up- and downregulated genes under C0 vs. N1, C0 vs. N2, and N1 vs. N2, respectively. Fold change ≥ 2. B Venn diagram of overlapped DEGs under C0 vs. N1 and C0 vs. N2. C, D KEGG pathway enrichment analysis of DEGs under C0 vs. N1, C0 vs. N2, respectively. E Pie chart showed the percent of A/B compartment switching under C0 vs. N1 and C0 vs. N2. F Gene expression features of A/B compartments. The gene expression (FPKM value) of A compartments, A to B switching compartments, different compartments, B to A switching compartments, and B compartments under C0 vs. N1 and C0 vs. N2, respectively
