Notes:
Summary Normally quiescent cortical tissue of pea roots can be induced, by severing the adjacent vascular cylinder of the root, to undergo redifferentiation to form new files of tracheary and sieve elements which bridge the wound. The development of vascular transfer cells is also induced. Redifferentiation is normally accompanied by division of the original cortical cells. The planes of cell division, especially those preceding sieve element formation, are aligned very precisely in adjacent cells, to produce smooth files of cells. In roots wounded 3–4 mm from the apex, bands of microtubules in the periphery of the cells (pre-prophase bands) form at sites which correspond to the expected planes of cell division.
