“…Cessation of cell division occurs after 3 cell generations (A7), or after Diaphragm development with asynchronous divisions. A similar situation has been already encountered in the cortex of maize roots [31,32,42]. Our personal observations of micrographs of median longitudinal sections of Thalassia roots indicate that a (7, 4) Fibonacci system [41] adequately describes the spatial pattern of cellular development (Fig.…”

Most plants are constructed from repeating modular units such as phytomers, merophytes, and cell packets. Even an organism as simple as the filamentous cyanobacterium Anabaena shows recurrent patterns of differentiated cellular structures, notably with respect to its heterocysts. These examples reflect the inherent rhythms established within developmental processes of living organisms. In the present article, attention is paid to repetitious production of idioblasts-isolated cells, or clusters of cells, with an identity different to that of neighbouring cells from which they are derived. In higher plant root tissues, idioblasts are contained within cell packets that grow up from mother cells during the course of a number of cycles of cell production. The heterocysts of Anabaena are also discussed; they, too, are a type of idioblast. The idioblasts of root tissues originate as small cells which result from unequal cell divisions. Such divisions are usually the final ones within a cell packet which has already undergone a number of division cycles and are characteristically located at one or both ends of a packet. The packet end walls are suggested to have a role in regulating division asymmetry. Idioblastic systems discussed are root cortical trichosclereids and diaphragm cells; in their earliest stage, the cells from which lateral root primordia arise are also considered as clusters of idioblasts because they, too, are the products of asymmetric divisions of pericyclic mother cells. The division patterns of all these idioblastic systems were modelled in a consistent way using L-systems, with the assumption that the age of a cell-packet end wall plays a special role in cell determination.

“…As an extension to the attempt by [13] that best models the meristem development applied to the primary roots of Zea mays, a similar kind of attempt could be made in the field of horticulture and life style. In the above approach the author builds a theoretical model in the meristem development where a complete control over this process is in the hands of the alogorithm, inhibition of the development process may lead to a poor growth of meristem where a new type of "bonsai" could be developed for life style companies.…”

“…The L-systems approach in ALAMEDA provides parametric and environmental sensitive modules considering the parameters like chronological and photo thermal time; however other systems define parametes like rank of organ and phenological stage, shape, size, position and angles [12]. Another theoretical study in the development of meristem in Zea mays, a model used to study the growth of meristem and its manipulation done by the bootstrap L-system algorithm simulates the cellular packet development comprising the cortical portion of the maize root primary meristem [13].…”

“…Such a neighborhood defines the transition zone (Ivanov and Dubrovsky, 2013). Furthermore, within the same cell file, the distance from the leaf base where the cell switches to another phase of growth may be different (Lück et al, 1997). …”

Mechanical Behavior of Cells within a Cell-Based Model of Wheat Leaf Growth

Understanding the principles and mechanisms of cell growth coordination in plant tissue remains an outstanding challenge for modern developmental biology. Cell-based modeling is a widely used technique for studying the geometric and topological features of plant tissue morphology during growth. We developed a quasi-one-dimensional model of unidirectional growth of a tissue layer in a linear leaf blade that takes cell autonomous growth mode into account. The model allows for fitting of the visible cell length using the experimental cell length distribution along the longitudinal axis of a wheat leaf epidermis. Additionally, it describes changes in turgor and osmotic pressures for each cell in the growing tissue. Our numerical experiments show that the pressures in the cell change over the cell cycle, and in symplastically growing tissue, they vary from cell to cell and strongly depend on the leaf growing zone to which the cells belong. Therefore, we believe that the mechanical signals generated by pressures are important to consider in simulations of tissue growth as possible targets for molecular genetic regulators of individual cell growth.
