Transcriptional regulation of xylem cell differentiation

To understand gene regulation network downstream of VND6, we produced a culture line harboring inducible VND6. As a control, we also produced a culture line harboring inducible SND1, which is another master gene that initiates xylem fiber cells. Using these culture lines, we found common and distinct gene regulation networks of two types of xylem cells, xylem fiber cells and tracheary elements. In addition, we revealed that a cis regulative element, the TERE sequence, was the binding site of VND6.
