The same fundamental questions that have driven enquiry into
cytoskeletal mechanics can be asked of the considerably less-studied, yet
arguably just as important, biopolymer matrix in the plant cell wall. In this
case, it is well-known that polysaccharides, rather than filamentous and tubular
protein assemblies, play a major role in satisfying the mechanical requirements
of a successful cell wall, but developing a clear structure–function understanding
has been exacerbated by the familiar issue of biological complexity. Herein, in
the spirit of the mesoscopic approaches that have proved so illuminating in the
study of cytoskeletal networks, the linear microrheological and strain-stiffening
responses of biopolymeric networks reconstituted from pectin, a crucial cell wall
polysaccharide, are examined. These are found to be well-captured by the glassy
worm-like chain (GWLC) model of self-assembled semi-flexible filaments.
Strikingly, the nonlinear mechanical response of these pectin networks is found
