Fig. 1: Chromosomal features of G. hirsutum and G. barbadense genomes with integration of genetics and epigenetics data.

a, Gene density in each chromosome. b, Transposable element (TE) content in each chromosome. For a and b, green lines represent data in G. hirsutum and blue lines represent data in G. barbadense. c, SNP density between G. hirsutum and G. barbadense. d, InDel density between G. hirsutum and G. barbadense. e, 5mC DNA methylation levels. f, 6mA DNA methylation levels. g, Histone modification levels of H3K4me3 (yellow histogram) and H3K9me2 (purple histogram). For c–g, the outer tracks show data in G. hirsutum and inner tracks show data in G. barbadense. All these data are shown in 1 Mb windows sliding 200 kb. The inner lines show syntenic blocks in homoeologous chromosomes between the A and D subgenomes.
