A nuclear-phased, chromosome-scale genome assembly of the dikaryotic fungus Puccinia striiformis f. sp. tritici (Pst) isolate 104E. (A) Karyoplot of the 18 chromosomes of haplotype A, showing CpG methylation and transposable element (TE) density as peaks, and gene density as heatmaps within chromosome ideograms (10 kbp sliding windows). Locations of centromeres, telomeres, secretome genes, the ribosomal DNA (rDNA) array, and assembly gaps are annotated as per the legend. The mating type loci are labeled in black text above the corresponding chromosomes. (B) Hi-C contact heatmap of the full dikaryotic genome assembly consisting of 36 chromosomes. The two nuclear haplotypes A and B display a clear signal of spatial separation.
