The phylogenic tree of plant VOZ transcription factor genes. The best representative Maximum-likelihood (ML) topology generated with the GTR + G + I model using RAxML for the 107 VOZ transcription factor coding sequences. Branch lengths indicate the number of nucleotide substitutions per site and are drawn to scale. All species abbreviations are listed in Fig. 1. A phylogenic tree reconstructed utilizing the Bayesian Inference (BI) method in MrBayes exhibits a similar topological structure (Additional file 2: Figure S1). Asterisks indicate the focal nodes were well supported in both RAxML (bootstrap values of 90) and MrBayes (posterior probability support of 95%). Individual clades are colored for ease of visualization
