EMSAs of XTR1 binding to the promoter fragments of xyn1. A–E The promoter fragments of Pxyn1 (− 750 ~ − 538 bp) (A), Pxyn1 (− 538 ~ − 321 bp) (B), and Pxyn1 (− 321 ~ − 91 bp) (C), Pxyn1 (− 321 ~ − 217 bp) (D), and Pxyn1 (− 217 ~ − 91 bp) (E) were, respectively, incubated with the purified recombinant XTR1 DBD protein and subjected to electrophoresis analyses
