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.

Fifteen days after the callus isolation on a SI medium, it was possible to observe in a sample of 'RB93509' cultivar the connection of shoot meristems with procambium tissues (Figure 2B).
Despite the lack of knowledge on the molecular nature of this network, the available data implicate gradually restricted transport routes of the plant hormone auxin in defining sites of procambium formation [16].
