Fig. 1From: Genome-wide analysis of the basic leucine zipper (bZIP) transcription factor gene family in six legume genomesPhylogenetic tree of legume and Arabidopsis bZIP genes. bZIP protein sequences were aligned by Clustal X and the phylogenetic tree was constructed using PhyML by the maximum likelihood method. Bootstrap values are based on 100 replicates. Genes on branch ends from different species are denoted by different colored circles. The legume bZIP proteins were grouped into 11 distinct clades (A–I, S, U), which are indicated by colored branchesBack to article page
