EMSAs of XTR1 binding to the promoter fragments of xyn1 and xyn2. A–D The promoter fragments of Pxyn1a (− 750 ~ − 91 bp) (A), Pxyn1b (− 1500 ~ − 750 bp) (B), Pxyn2a (− 750 ~ − 43 bp) (C), and Pxyn2b (− 1500 ~ − 750 bp) (D) were, respectively, incubated with the purified recombinant XTR1 DBD protein and subjected to electrophoresis analyses
