[The principles of data formalization for building the genetic-morphological model of shoot development in flowering plants].
Shoot system of a plant can be divided into elementary molecules composed of phyllome, internode, and meristem of the lateral bud. The capacity of plants for open growth is manifested as multiple reproductions of the modules. These main principles of plant structural organization can be used to formalize and integrate the data from various disciplines studying the shoot development--genetics of development, morphology, etc. At the example of model species Arabidopsis thaliana we show that the data on genetic control of shoot development can be considered in terms of individual modules reorganization. Several variants of the modules structural reorganization are allowed: reduction or transformation of phyllome, change in the internode length, and triggering active/inactive status of the lateral shoot meristem. Each variant of the module structure corresponds to specific pattern of genes activity. Such integration of the data on genetic and structural aspects of morphogenesis can form a basis for mathematical modeling of plant development.
