“…We propose, therefore, that for each species there is a single, unique division system, but that in planta there can be some variability in its operation. This conforms to the situation in the many plant apical meristems where it is possible to deduce a certain unique deterministic (and usually recurrent) division system from which small deviations in the derived pattern of cells also arise (Barlow 1991;Barlow et al 2001). Thus, it has to be considered whether there is some inherent feature of the cambial zone which determines the cell division system itself.…”

The secondary phloem of dicotyledonous trees and shrubs is constructed of sieve tube cells (S) and their companion cells, as well as parenchyma (P) and fibre (F) cells. Different species have characteristic sequences of these S, P and F cells within the radial files of their phloem. The sequences are recurrent, and are evidence of rhythmic cell determination and differentiation. A model was devised to account for the sequences found in various dicot tree species. It is based on the pattern of radial displacement of cells through a gradient of morphogen which supports secondary phloem development. According to this model, each tree species shows a particular pattern of post-mitotic cellular displacement along each radial file as a result of a corresponding sequence of periclinal division in the cambial initial and its descendents. The divisions and displacements ensure that at each timestep (equivalent to an interdivisional interval) each cell resides in a specific location within the morphogenic gradient. Cells then emerge from the post-mitotic zone of cell determination, having acquired different final positional values. These values lie above a series of thresholds that permit the respective determination and subsequent differentiation of one or other of the three cell types S, P and F. The recurrent nature of the sequences of the three cell types within each radial cell file, as well as their tangential banding, are a consequence of a shared rhythmic spatio-temporal pattern of periclinal cambial divisions. With a single set of morphogen parameters required for cell determination, and using three positions for cambial cell divisions, all the cellular sequences of secondary phloem illustrated in the literature can be accounted for.

“…For instance, the ratio of anticlinal and periclinal divisions in the segments of fern gametophyte is responsible for the development of their heart-like shape [7]. The orientation of divisions and shape of the apical cell determine the cellular and tissue architecture of fern root [3] and Psilotum nudum shoot as well [4]. These generative characters of the cellular architecture were effectively used in the plant pattern modeling being used as rules or shape grammars for the self-generation in the cellular automata approach [45] or in the widely spread L-systems approach for the simulation of plant development [4,8].…”

“…Moreover, the genealogical tree of the concrete embryo demonstrates its own individual development from the zygote, which could be compared to the individual development of othe ther embryo in order to estimate the regularity of their development. This approach is completely different from known L-systems method (for instance, [4]), where the proposed transformations of cells during development are compared statistically to the morphogenetic processes found in nature.…”

“…Another comprehensive approach of the formative tissue development simulation was made by P. Barlow and his colleagues [4], where the maps-L systems applied to the apical cell of Psilotum nudum were analyzed. In this work the basic assumption meaning, that each the cell wall is subdivided into the zones labeled, was successfully verified.…”

“…Higher plants are the unique organisms because it is possible in most cases to trace back all divisions of their cells according to the shape of cell walls [4,15,24,25]. First stages of embryogenesis -the segmentation and formation of blastomers, are critical for the elaboration of the main embryo axes of polarization and determination of most tissue initials [18,22,42].…”

Abstract. Plants and animals have highly ordered structure both in time and in space, and one of the main questions of modern developmental biology is the transformation of genetic information into the regular structure of organism. Any multicellular plant begins its development from the universal unicellular state and acquire own species-specific structure in the course of cell divisions, cell growth and death, according to own developmental program. However the cellular mechanisms of plant development are still unknown. The aim of this work was to elaborate and verify the formalistic approach, which would allow to describe and analyze the large data of cellular architecture obtained from the real plants and to reveal the cellular mechanisms of their morphogenesis. Two multicellular embryos of Calla palustris L. (Araceae) was used as a model for the verification of our approach. The cellular architecture of the embryos was reconstructed from the stack of optical and serial sections in three dimensions and described as graphs of genealogy and space adjacency of cells. In result of the comparative analysis of these graphs, a set of regular cell types and highly conservative pattern of cell divisions during five cell generations were found. This mechanism of cellular development of the embryos could be considered as a developmental program, set of rules or grammars applied to the zygote. Also during the comparative analysis the finite plasticity in cell adjacency was described. The structural equivalence and the same morphogenetic potencies of some cells of the embryos were considered as the space-temporal symmetries. The symmetries were represented as a set of regular cell type permutations in the program of development of the embryo cellular architecture. Two groups of cell type permutations were revealed, each was composed of two elements and could be interpreted as the mirror and rotational space symmetries. The results obtained as well as the developed approach can be used in plant tissue modelling based on the real, large and complex structural data.
