Mechanical forces in plant growth and development.
Plant cells perceive forces that arise from the environment and from the biophysics of plant growth. These forces provide meaningful cues that can affect the development of the plant. Seedlings of Arabidopsis thaliana were used to examine the cytoplasmic tensile character of cells that have been implicated in the gravitropic response. Laser-trapping technology revealed that the starch-containin...
متن کاملThe role of mechanical forces in plant morphogenesis.
The shape of an organism relies on a complex network of genetic regulations and on the homeostasis and distribution of growth factors. In parallel to the molecular control of growth, shape changes also involve major changes in structure, which by definition depend on the laws of mechanics. Thus, to understand morphogenesis, scientists have turned to interdisciplinary approaches associating biol...
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...
متن کاملPlant Morphogenesis: A Role for Mechanical Signals
The current paradigm for plant morphogenesis dictates that cortical microtubules serve as a template for the assembly of the cellulosic wall which, in turn, controls cell expansion. A new study provides direct evidence that tissue-level tension can serve as a mechanical signal to align cortical microtubules, thus establishing a critical feedback mechanism for the morphogenetic process.
متن کاملThe impact of mechanical forces in heart morphogenesis.
Congenital heart disease (CHD) is the most common birth defect in humans and results from deficient cardiac development, a complex process that is not completely understood. The heart starts to function before its morphogenesis is complete and the increasing needs of the growing embryo for oxygen and nutrients demand a proportional increase in the performance of the organ. We review recent find...
