Modeling plant morphogenesis.
Applications of computational techniques to developmental plant biology include the processing of experimental data and the construction of simulation models. Substantial progress has been made in these areas over the past few years. Complex image-processing techniques are used to integrate sequences of two-dimensional images into three-dimensional descriptions of development over time and to e...
متن کاملPlant morphogenesis: Designing leaves
Leaves exhibit a wide range of form and function: as well as the flattened photosynthetic organs we are most familiar with, modifications of leaf morphology produce the rigid spines of cacti, the cup-shaped insect traps of pitcher plants, colorful flower parts such as petals and some of the tendrils used for attachment by climbing plants. One fundamental choice in leaf architecture is whether t...
متن کاملCategorical Description Of Plant Morphogenesis
This article presents formalistic tool for description of structural and biochemical relations between cells in the course of development of the body of plants. This is flexible formalistic space, based on the Category theory and the Petri Net approach, which embeds and mutually supplements biological data from methodically different sources. Relation between functional and morphological ways o...
متن کاملPlant Morphogenesis: Life on a different plane
Arabidopsis ton mutant cells do not make the bands of microtubules that normally predict cell-division planes; the planes are irregular, yet seedlings develop to maturity. Is cellular morphogenesis important for plant form?
متن کاملPhysical Forces Regulate Plant Development and Morphogenesis
Plant cells in tissues experience mechanical stress not only as a result of high turgor, but also through interaction with their neighbors. Cells can expand at different rates and in different directions from neighbors with which they share a cell wall. This in connection with specific tissue shapes and properties of the cell wall material can lead to intricate stress patterns throughout the ti...
