Genome-Wide Investigation and Expression Profiling of HD-Zip Transcription Factors in Foxtail Millet (Setaria italica L.)

Figure 1

Phylogenetic tree of HD-Zip transcription factors in foxtail millet, maize, rice, green foxtail, and sorghum. The unrooted phylogenetic tree was produced with Clustal X2.0 by the neighbor-joining (NJ) method with 1000 bootstrap replications. The tree was divided into four subfamilies designated I to IV, with each HD-Zip family being indicated by a specific color.
