Figure 3

Venn diagrams of gene expression evolution in allopolyploid cotton. The numbers indicate genes classified as up-regulated in any wild polyploid species in comparison to the mid-parent values (MPV; estimated from a 1:1 RNA mix from the diploids G. arboreum and G. raimondii). Intersections denote genes shared by two or more of the three wild forms of the allopolyploids (wild G. hirsutum, wild G. barbadense and G. tomentosum).
