Both xylem and phloem are derived from cell divisions in vascular meristems known as the cambium and procambium. One major component that influences several aspects of plant vascular development, is a signalling module characterised by a peptide ligand called TDIF that is expressed in the phloem, and its cognate receptor, PXY which is procambium expressed.
