Evolution of WOX family. (A) Alignment of WOX homeodomains from different model plants. Phylogenetic analysis of homeodomain sequences was conducted using MEGA3.0 (Kumar et al., 2004). Protein sequences were obtained from published bioinformatics data (Haecker et al., 2004; Mukherjee et al., 2009; van der Graaff et al., 2009; Zhang et al., 2010; Nardmann and Werr, 2012, 2013; Lian et al., 2014; Zeng et al., 2015). Red box indicates sequence for classification of three clades. (B) Possible evolutionary route of WOX family genes.
