Chromosomal distribution of MAPKKK genes in G. raimondii. The 89 candidate MAPKKK genes were matched to 13 chromosome of the G. raimondii genome. The nomenclature of MAPKKK genes in G. raimondii follows its homology with Arabidopsis MAPKKK proteins. The chromosome numbers from D1 to D13, were consistent with the newly-updated interspecific genetic map of allotetraploid cultivated cotton species38. The names of the scaffolds from the G. raimondii genome are indicated in brackets.
