“…Whereas the cortical microtubules are randomly oriented in the fi ber initials, they become oriented transversely to the long axis of the cell as the fi ber begins to elongate. The fi bers undergo dramatic elongation, reaching lengths 1000 to 3000 times greater than their diameters (Peeters et al, 1987;Song and Allen, 1997). Elongation occurs via a diffuse mechanism; that is, it occurs throughout the length of the fi ber ( Fig.…”

The onset of rapid cell elongation occurred at different distances from the apex in various tissues of the primary root of maize (Zea mays L.). Furthermore, the comparison of these distances with those determined for the cessation of mitotic divisions revealed a considerable discrepancy. The onset of rapid cell elongation was realized much farther from the root apex than the cessation of cell divisions and therefore a distinct region could be distinguished in every examined maize root tissue. This region was denoted the region of postmitotic 'isodiametric' cell growth. Cells in this region grew in width as well as in length and obtained approximately a square-isodiametric shape. They were also characterized, as are cells in the meristem, by intense nucleic-acid metabolism. This prominent postmitotic 'isodiametric' cell growth was observed in both polyploid and diploid tissues, and indicates that postmitotic 'isodiametric' cell growth, like mitotic division and cell elongation growth, represents an important developmental stage in plant cell ontogeny.

Davidonis, G. H. 1989. Fiber development in preanthesis cotton ovules. -Physiol. Plant. 75: 290-294. A tissue culture method was developed to investigate the production of cotton (Gossypium hirsutum L. cv. Texas Marker-1) fibers in vitro. Ovules were excised from 3, 5, 7 and 9 days preanthesis ovaries and placed on an agar-solidified, modified Murashige and Skoog medium containing 2.3 yiM kinetin and 0.45 [.iA/-2,4-dichlorophenoxyacetic acid or 2.3 |xM kinetin and 10.7 [iM naphthaleneacetic acid. Ovules formed fibers and callus tissue. Fibers formed in vitro were up to 10 mm long, 10-22 [xm wide and the cell wall was 1-3 [xm thick. Callus tissue cells were subcultured for over 25 weeks and their degree of elongation was monitored. The ability of ovulederived cells to direct expansion in a longitudinal direction diminished, while lateral expansion increased with time in culture.
