Developmental and stress responses of single root cell mechanical properties
Plant Science Research WeeklyClearly, the mechanical properties of plant cell walls have important implications for growth and development, but they are not necessarily easy to measure, especially in intact, living tissues. Here, Alonso-Baez et al. used Brillouin microscopy and molecular rotors to characterize cell wall properties…
Under pressure: Interdisciplinary research into the mechanics of the cell wall
Plant Science Research WeeklyThe architecture of the plant cell wall is very intricate: strings of cellulose microfibrils provide structure while allowing the cell to expand and grow. This growth is primarily driven by turgor pressure, which applies pressure and allows for expansion in all directions. While the general mechanism…
Perspective: Multiple mechanism behind plant bending
Plant Science Research WeeklyBending or folding in plants is influenced by different factors such as environmental conditions (nutrient, water, light, gravity), abiotic or biotic stress, cell wall properties, and cell differential growth. Jonsson et al. explain how bending is achieved by considering molecular mechanisms, mathematical…
