Fig 2. Unrooted phylogenetic tree representing relationships among WRKY domains of Musa and Arabidopsis.

Amino acid sequences of WRKY genes were aligned with clustal W and 1000 bootstrap values in neighbor-joining method in MEGA 5.2.Branch name of sub trees are colored indicating different WRKY groups and subgroups. Triangle symbols indicated that significant expression in susceptible or resistant cultivars. Ο symbol shows that no genes were expressed, and arcs symbol showed that up-regulated in resistant and down-regulated in susceptible cultivar during nematode infection.
