Figure 2. Alignment among the amino acid sequences of ThERF15, ThERF39 and ThRAP2.3 with ERFs of Arabidopsis and Populus protein sequences using the ClustalX program.

The AP2-ERF domain, the YRG element, the WLG motif, and the nuclear localization sequence are marked with different kinds of overlines, as indicated above the sequence alignment. Amino acid position numbers are indicated to the right of the sequence.
