Abstract In plants, cellulose microfibrils (CMFs) play a major role in cell wall mechanics. Plant epidermal peels have been widely used as model system to study the relationship between CMF arrangement and mechanical properties of wall. Recently, vibrational sum frequency generation (SFG) spectroscopy imaging has discovered that CMFs cell-cell junction regions (i.e., edges each cell) periclinal are preferentially aligned (anisotropic) perpendicular anticlinal plane, while those face crossed-polylamellate (isotropic) structure possessing all possible orientations. Here, we studied effect these regiospecific orientations on tensile peeled plant walls using finite element analysis (FEA). The FEA simulation showed anisotropic fibers region elongated hexagonal cells amplified anisotropy behavior under stretching exhibited strain-dependent Poisson’s ratio with nonlinear behavior. SFG suggested that, region, there alterations chain conformation within and/or CMF-CMF bundling upon stretch.

Abstract Plant cell wall (CW)-like soft materials, referred to as artificial CWs, are composites of assembled polymers containing micro-/nanoparticles or fibers/fibrils that designed mimic the composition, structure, and mechanics plant CWs. CW-like materials have recently emerged test hypotheses pertaining intricate structure–property relationships native CWs fabricate functional materials. Here, research on is reviewed by distilling key studies biomimetic primarily composed polysaccharides, including cellulose, pectin, hemicellulose, well organic like lignin. Micro- nanofabrication composites, characterization techniques, in silico reviewed, with a brief overview current potential applications. Micro-/nanofabrication approaches include bacterial growth impregnation, layer-by-layer assembly, film casting, 3-dimensional templating microcapsules, particle coating. Various techniques necessary for comprehensive mechanical, chemical, morphological, structural analyses demonstrate versatility real-life applications, biomass conversion, pulp paper, food science, construction, catalysis, reaction engineering. This review seeks facilitate rational design thorough CW-mimetic goal advancing development innovative elucidating complex inherent

Abstract During plant development, the mechanical properties of cell walls must be tuned to regulate growth cells. Cell involves significant stretching walls, yet little is known about under such substantial deformation, or how these change development. Here, we investigated behavior Arabidopsis leaf epidermal cells being stretched. We found that arise from wall, which behaves as a fibrous network material. The epidermis exhibited non-linear stiffening fell into three regimes. Each regime corresponded distinct nonlinear behaviors in terms transverse deformation (i.e., Poisson effect) and unrecoverable plasticity). Using model, demonstrated transition reorientation bending-dominated stretch-dominated modes cellulose microfibrils cause behaviors. more pronounced at later developmental stages. Finally, show spiral2-2 mutant has anisotropic properties, likely contributing spiraling leaves. Our findings reveal nature gives high degree tunability allows adjust support proper
