Xylem parenchyma cells deliver the H2O2 necessary for lignification in differentiating xylem vessels

Lignification in Zinnia elegans L. stems is characterized by a burst in the production of H(2)O(2), the apparent fate of which is to be used by xylem peroxidases for the polymerization of p-hydroxycinnamyl alcohols into lignins. A search for the sites of H(2)O(2) production in the differentiating xy...
