The apical cell of fern roots and shoots: an appraisal of its functional role in development
Published online by Cambridge University Press: 05 December 2011
Synopsis
A brief review of the Apical Cell Theory and its relationship to apical growth in pteridophytes is presented. Currently there are two concepts regarding the importance of the apical cell during development. One group of investigators has presented evidence to demonstrate that the apical cell is mitotically active only during early initiation and organisation of apical meristems. Soon the apical cell becomes essentially inactive in cell division, and may undergo endopolyploidy. The second group has provided evidence in support of the original tenet that the apical cell plays an important and continuing role in shoot and root development and does not undergo endopolyploidy. Curiously enough, evidence for both concepts is based essentially upon the same procedures and techniques: histogenesis, determination of the mitotic index and cell-cycle durations, labelling with 3H-thymidine, and cytophotometric measurements of DNA content of the apical cell and subjacent cells.
