Phylogenetic tree derived from NBS-encoding genes containing TIR domain in G. arboreum, G. raimondii, G. hirsutum and G. barbadense. The neighbor-joining tree was constructed using the sequences of 131 TIR-NBS proteins in the four cotton species. Bootstrap values were indicated on the branches. Each NBS protein was labeled by its name (Additional file 1: Table S1). The filled circles, the hollow circles, the solid triangles and the hollow triangles represented the genes of G. arboreum, G. raimondii, G. hirsutum and G. barbadense, respectively
