Figure 1. AtWIND1 orthologs are widely conserved in land plants. (A) A phylogenetic tree of putative WIND orthologs in 18 representative plant species. Another Arabidopsis AP2/ERF transcription factor BBM (AT5G17430) was employed as an outgroup. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (500 replicates) is shown next to the branches. Arabidopsis WIND1–4 were highlighted in red. All data set files used in this analysis are shown in Table S1. (B) Overrepresented peptide motifs among putative WIND orthologs. BBM (AT5G17430) was employed as an outgroup. Gene names and their plant sources are provided in Table 1. Each overrepresented peptide motif is automatically numbered and colored by the SALAD program for descriptive purpose.
