Phylogenetic tree analysis of the PHD finger proteins from Arabidopsis and Brassica rapa. The tree was determined by using MEGA6.06 software with the Neighbor–Joining (NJ) algorithm and a bootstrap analysis of 1000 replicates. The PHD finger proteins were clustered into six major groups (A-F). Proteins from Arabidopsis and B. rapa are indicated by red and green colors, respectively
