“…For more than half a century it has been suggested that the geometric interplay of local forces and locally anisotropic cell wall mechanics lies behind much of the complexity of plant morphogenesis ( Green 1964 ). Evidence elaborating this view is now taking shape, with leaf laminae ( Zhao et al 2020 ), shoot apices ( Sampathkumar et al 2019 ; Peaucelle 2020 ; Moulia et al 2022 ), and pollen tubes ( Cameron and Geitmann 2018 ) as examples and with feedback from local force to cellulose orientation as a key component ( Jonsson et al 2022 ). The forces concerned are often constant, but nonconstant endogenous forces are associated with the slowly oscillating growth of pollen tubes ( Pietruszka et al 2018 ), opening and closing of stomata ( Auler et al 2022 ), and deformations around pulvini during rapid plant movements ( Mano and Hasebe 2021 ).…”

Environmental influences and differential growth subject plants to mechanical forces. Forces on the whole plant resolve into tensile forces on its primary cell walls and both tensile and compression forces on the secondary cell-wall layers of woody tissues. Forces on cell walls are further resolved into forces on cellulose microfibrils and on the non-cellulosic polymers between them. Many external forces on plants oscillate, with time constants that vary from seconds to milliseconds. Sound waves are a high-frequency example. Forces on the cell wall lead to responses that direct the oriented deposition of cellulose microfibrils and the patterned expansion of the cell wall, leading to complex cell and tissue morphology. Recent experiments have established many of the details of which cell-wall polymers associate with one another in both primary and secondary cell walls, but questions remain about which of the interconnections are load-bearing, especially in primary cell walls. Direct cellulose-cellulose interactions appear to have a more important mechanical role than was previously thought, and some of the non-cellulosic polymers may have a role in keeping microfibrils apart rather than cross-linking them as formerly envisaged.
