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 کاملMechanical forces during muscle development
Muscles are the major force producing tissue in the human body. While certain muscle types specialize in producing maximum forces, others are very enduring. An extreme example is the heart, which continuously beats for the entire life. Despite being specialized, all body muscles share similar contractile mini-machines called sarcomeres that are organized into regular higher order structures cal...
متن کاملSnapShot: Mechanical Forces in Development I
Cell-type-specific F-actin structures and myosin motors are key generators of the forces that drive tissue morphogenesis in developing organisms. These cytoskeletal elements mediate defined cell deformation and control the arrangement of cell-cell contacts. This SnapShot presents a selection of morphogenetic processes, the analysis of which has pioneered specific types of F-actin/myosin-mediate...
متن کاملSnapShot: Mechanical Forces in Development II
The forces shaping an organism are not exclusively produced by actin/myosin II networks. In part II of this SnapShot, we present various alternative mechanisms. In addition to driving morphogenesis, cells use mechanical forces to sense and react to the specific mechanical properties of their environment. Also, we present a selection of experimental tools commonly used in force analysis.
متن کاملMechanical Forces of Fission Yeast Growth
Mechanical properties contribute to the control of cell size, morphogenesis, development, and lifestyle of fungal cells. Tip growth can be understood by a viscoplastic model, in which growth is derived by high internal turgor pressure and cell-wall elasticity. To understand how these properties regulate growth in the rod-shaped fission yeast Schizosaccaromyces pombe, we devised femtoliter cylin...
