SlWRKY06, SlWRKY17, StWRKY06, and SlWRKY07 (group IIb members) all carried the common bZIP-Maf-small domain (Basic leucine zipper (bZIP) domain of small musculoaponeurotic fibrosarcoma (Maf) proteins: cd14717), which might be involved in various cell functions including proliferation, apoptosis, survival, and morphogenesis (Hang and Stein, 2011; Vanderford, 2011; Kannan et al., 2012). This evidence concerns the gene MAF and fibrosarcoma.
