Nucleotide diversity and Tajima’ D test depict the selection pressure on GhBM during G.hirsutum domestication. A Nucleotide diversity in a fragment containing GhBM (including 3000 bp upstream, the coding region, and 3000 bp downstream). B, C To investigate whether the fragment containing GhBM was subject to selection pressure, nucleotide diversity (B) and Tajima’s D test (C) and were analyzed based on the total number of polymorphic sites in this fragment (including 200 kb upstream, the coding region, and 200 kb downstream). Gb, G. barbadense. Gh, G. hirsutum. D, E Comparison of linkage disequilibrium in the 1-Mb region around Beauty Mark between G. barbadense (D) and G. hirsutum (E)
