Modelling Development in Plant Anatomy - Modelling Development in Plant Anatomy - Open Access Pub

Four rules for good anatomical modeling of plants are explored. First, the cell is the reference source for modelling at any level. Second, developmental signaling occurs between few cells, about 12. Third, rules of are algorithmic and not simply physical forces as proposed by Thompson. Finally, it is desirable to proposed a likely alternative model that can be discounted. The main value of modelling is selecting data for modelling rather than the by a biased investigator.

The wide variety of problems requires an equally broad range of applications yet as a somewhat new methodology no ground rules have developed for modelling, each problem with its basic assumptions led to a somewhat specialized approach. For example, phyllotaxy (leaf arrangement) has been modelled along the lines of available space 4, pressure contact 5 diffusion of morphogens6. and they require special applications about geometry, force, and diffusion, respectively. Modelling of plant anatomy comes in a variety of contexts. Three types of models used in biological development are (1) conceptual or the meaning of words such as sequence, origin, differentiation, etc.; (2) in vivo and in vitro or using living models and (3) in silica where models are paper-and-pencil or computer expressions 7. These three approaches are progressively more detailed as employed by the development of vascular bundles in monocots 8. All Changes are at the Cellular Level. Of all the levels of organization in plant structure that of the cell stands since the formulation of the cell theory as the unit of function and reproduction 9. Structurally the plant cell is composed of facets that are arranged as an enclosure making function and multiplication possible. The cell then should also be the unit of modelling by which all other levels are possible. From a hierarchical point of view there are levels below and above that of the cell but are generated within the cellular enclosure and are active at different levels (Figure 1). Consider the levels of cell, tissue, organ and individual organism exemplified by a simplified plant leaf. One tissue is the epidermis which is seen as a composite of cell features, i.e, facets, vertices and contents and tissue features such as the middle lamella that holds cells together or a layer of cutin spread over the exposed facets. The contents of these features are made in cells and transported to
