Tomographic Analysis of Cellulose Meshing: Surface-to-Depth Gradient in Plant Cell Walls

Original video: https://youtu.be/ZeQ0Qts-Abw

The meshing is found in increased amounts proximal to the leading edge of the lamella, i.e., at the surface of the cell wall. Tomograms taken close to the top of the cell wall are enriched in meshing in comparison to tomograms taken deeper in the cell wall where the cellulose fibers appear to be more ordered with less meshing present.
