“…This cell b is an analogue of a 3-sided structural initial, or apical cell; such a cell is characteristic of root and shoot apices of certain ferns. The operation of system S 5-5 was found to produce a sequence of notional cells which faithfully reproduce the spiral patterns of actual biological cells observable upon the apices of roots and shoots of the fern, Psilotum nudum (Barlow et al 2000, 2004a, Barlow and Lück 2004.…”

“…The auto-reproductive feature inherent to L-system algorithms, as applied by Barlow et al (2000Barlow et al ( , 2004a, relates both to individual stem cells and to the generative centres of plant roots. Also inherent to the algorithms is the production of new cell boundaries, or cell walls.…”

“…The whole cell group constitutes an auto-reproductive, self-maintaining generative centre. (Adapted from Barlow et al 2000) cell b. Then, in accordance with the operation of system S 5-5 , cell a proceeds to repeat the same sequence of cell production as does cell b, except that the handedness of its cell productions is the contrary to those from cell b.…”

Many facets reflecting the autopoietic process of Life and Living can be found in plant roots at many levels relevant to their organisation, from cells to ecosystems. At each level, there are sub-processes dedicated to both the autoreproduction and the self-maintenance of that level, these processes being contained within a boundary appropriate for that level. Autoreproduction and self-maintenance unite with a third sub-process, cognition, and provide the basis of a coherent multi-levelled programme of root-research.

In contrast to seed plants, the roots of most ferns have a single apical cell which is the ultimate source of all cells in the root. The apical cell has a tetrahedral shape and divides asymmetrically. The root cap derives from the distal division face, while merophytes derived from three proximal division faces contribute to the root proper. The merophytes are produced sequentially forming three sectors along a helix around the root axis. During development, they divide and differentiate in a predictable pattern. Such growth causes cell pattern of the root apex to be remarkably regular and self-perpetuating. The nature of this regularity remains unknown. This paper shows the 2D simulation model for growth of the root apex with the apical cell in application to Azolla pinnata. The field of growth rates of the organ, prescribed by the model, is of a tensor type (symplastic growth) and cells divide taking principal growth directions into account. The simulations show how the cell pattern in a longitudinal section of the apex develops in time. The virtual root apex grows realistically and its cell pattern is similar to that observed in anatomical sections. The simulations indicate that the cell pattern regularity results from cell divisions which are oriented with respect to principal growth directions. Such divisions are essential for maintenance of peri-anticlinal arrangement of cell walls and coordinated growth of merophytes during the development. The highly specific division program that takes place in merophytes prior to differentiation seems to be regulated at the cellular level.Electronic supplementary materialThe online version of this article (doi:10.1007/s00425-013-1950-9) contains supplementary material, which is available to authorized users.
