Genome-Wide Identification, Characterization, and Expression Analysis of the Grapevine Superoxide Dismutase (SOD) Family

Figure 3

Phylogenetic tree of 77 SOD proteins from grape and other plants including Arabidopsis thaliana, Oryza sativa, Sorghum bicolor, Populus trichocarpa, Amborella trichopoda, Cucumis sativus, Solanum lycopersicum, and Gossypium raimondii. The Jones-Taylor-Thornton model with -distance was chosen to conduct the phylogenetic tree. The bootstrap value was set as 1000. The SOD genes were classified into two major groups and five subfamilies (groups a, b, c, d, and e which have red, blue, yellow, purple, and green branches, respectively).
