Fig. 2.

Dendrogram of poplar and Arabidopsis bZIP members. The dendrogram was drew by MEGA7 with the Maximum Likelihood method and JTT + G + F model. Different groups are marked with different colors. The groups were named with letters representing some of their important members (A for ABF/AREB/ABI5, C for CPRF2-like, G for GBF, H for HY5), protein size (B for big, S for small), or alphabetically
