Fig. 3From: Genome-wide characterization and expression analyses of superoxide dismutase (SOD) genes in Gossypium hirsutum Syntenic relationships among SOD genes from G. hirsutum, G. raimondii and G. arboretum. G. hirsutum, G. raimondii and G. arboretum chromosomes are indicated in purple, blue and red, respectively. The putative orthologous SOD genes between G. hirsutum and G. raimondii, G. hirsutum and G. arboretum, and G. raimondii and G. arboretum are connected by yellow, red and orange lines, respectively. The segmental duplication genes are connected by black lines Back to article page
