Extended Data Fig. 1: Genome-wide analysis of chromatin interactions in papaya SunUp and Sunset genomes.

Hi-C interactions heatmap diagram at 500Kb resolutions for the entire nine chromosomes and HSY region were showed from top left to bottom right in order (1–9, indicate Chr1-Chr9, HSY indicates hermaphrodite-specific Yh chromosome region). The color bars beside heat maps indicate strong interactions in red and weak interactions in yellow.
