Hi-C and Circos plots of two mahogany genomes (a) Hi-C map of the S. macrophylla and K. senegalensis genome showing genome-wide all-by-all interactions. The map shows a high resolution of individual chromosomes that are scaffolded and assembled independently. The heat map colors ranging from light pink to dark red indicate the frequency of Hi-C interaction links from low to high (0–10). (b) Circos plot of S. macrophylla and K. senegalensis genome. Concentric circles from outermost to innermost show (I) chromosomes and megabase values, (II) gene density, (III) GC content, (IV) repeat density, (V) LTR density, (VI) LTR Copia density, (VII) LTR Gypsy density and (VIII) inter-chromosomal synteny (features II-VII are calculated in non-overlapping 200 Kb sliding windows).
