Chromosomal distribution of MAPK genes in G. raimondii. The chromosome numbers are indicated at the top of each bar. The chromosome numbers from D1 to D5, and D7 to D12 were consistent with our newly-updated interspecific genetic map in allotetraploid cultivated cotton species reported recently (Zhao et al. [32]), and the scaffolds name from G. raimindii genome was showed in the bracket. Lines were drawn to connect duplicated genes. The nomaclature of MAPKs were based on the order of the chromosomes in G. raimondii.
