Plant cell growth in tissue.
Cell walls are part of the apoplasm pathway that transports water, solutes, and nutrients to cells within plant tissue. Pressures within the apoplasm (cell walls and xylem) are often different from atmospheric pressure during expansive growth of plant cells in tissue. The previously established Augmented Growth Equations are modified to evaluate the turgor pressure, water uptake, and expansive ...
متن کاملPlant Cell Growth and Elongation
The plant cell wall is a strong material that resists expansion when water is taken up by the protoplast; for cells to expand irreversibly, the existing wall architecture must be loosened to permit the insertion of newly synthesized wall polymers. Biochemical approaches have identified changes in wall composition that occur during growth and some of the enzymes involved in wall loosening, whils...
متن کاملPlant growth: Roots in the cell cycle
Overexpression in transgenic plants of a B-type cyclin--thought to regulate cell-cycle progression to mitosis--causes structures such as roots to grow faster than normal, indicating that the rate of cell division may be a constraint on plant growth.
متن کاملTurning a plant tissue into a living cell froth through isotropic growth.
The forms resulting from growth processes are highly sensitive to the nature of the driving impetus, and to the local properties of the medium, in particular, its isotropy or anisotropy. In turn, these local properties can be organized by growth. Here, we consider a growing plant tissue, the shoot apical meristem of Arabidopsis thaliana. In plants, the resistance of the cell wall to the growing...
متن کاملVirtualLeaf: an open-source framework for cell-based modeling of plant tissue growth and development.
Plant organs, including leaves and roots, develop by means of a multilevel cross talk between gene regulation, patterned cell division and cell expansion, and tissue mechanics. The multilevel regulatory mechanisms complicate classic molecular genetics or functional genomics approaches to biological development, because these methodologies implicitly assume a direct relation between genes and tr...
