“…Due to the aggravation of plasmolysis caused by water loss, protoplast would produce a certain tensile stress on the plasma membrane by the action of Hechtian strands [27], which is expected to increase the hardness of the stressed cellular structures according to the model of cellular tensegrity [28], this model is widely accepted for describing animal cells, and was also proposed to be appliable to plant cells [29]. Our work described here verified experimentally the following two important predictions in plant cell mechanics.…”

The plant cell mechanics, including turgor pressure and wall mechanical properties, not only determine the growth of plant cells, but also reflect the functional and structural changes of plant cells under biotic and abiotic stresses. However, there are currently no appropriate techniques allowing to monitor the complex mechanical properties of living plant cells non-invasively and continuously. In this work, quartz crystal microbalance with dissipation (QCM-D) monitoring technique with overtones (3–9) was used for the dynamic monitoring of adhesions of living tobacco BY-2 cells onto positively charged N,N-dimethyl-N-propenyl-2-propen-1-aminiumchloride homopolymer (PDADMAC)/SiO2 QCM crystals under different concentrations of mannitol (CM) and the subsequent effects of osmotic stresses. The cell viscoelastic index (CVIn) (CVIn = ΔD⋅n/ΔF) was used to characterize the viscoelastic properties of BY-2 cells under different osmotic conditions. Our results indicated that lower overtones of QCM could detect both the cell wall and cytoskeleton structures allowing the detection of plasmolysis phenomena; whereas higher overtones could only detect the cell wall’s mechanical properties. The QCM results were further discussed with the morphological changes of the BY-2 cells by an optical microscopy. The dynamic changes of cell’s generated forces or cellular structures of plant cells caused by external stimuli (or stresses) can be traced by non-destructive and dynamic monitoring of cells’ viscoelasticity, which provides a new way for the characterization and study of plant cells. QCM-D could map viscoelastic properties of different cellular structures in living cells and could be used as a new tool to test the mechanical properties of plant cells.

“…However, very few molecules functioning as linkers within the continuum has been identified (reviewed in Baluška et al, 2003;Kasprowicz et al, 2011). Genomic data suggest that plants are devoid of proteins typically involved in the construction of complexes linking the interior of animal cells to extracellular matrix, such as integrins, filamin, or tensin (Hussey et al, 2003).…”

A technique for the selective loosening of the cell wall structure and the isolation of proteins permanently knotted in the cell walls was elaborated. Following treatment with collagenase, some proteins, such as calreticulin (CRT) and auxin binding protein 1 (ABP1) were released from purified cell walls, most probably through destruction of respective interacting proteins. The results were confirmed by the immunolocalization of the ABP1 and CRT with confocal and electron microscopy. On the other hand, potential substrates of collagenase, among them annexin 1 have been recognized. Mass spectra of annexin 1 obtained after collagenase digestion and results from analysis of potential cleavage sites suggested that the mechanism of enzyme cleavage might not depend on the amino acid sequence. Summarizing, collagenase was found to be a very useful tool for exploring molecules involved in the functioning of cellular peripheries.

“…In fact, the situation appears to be the reverse. Mechanical stresses, varying sharply on subcellular scales, integrated over the tissues and dynamically orchestrated at the organismal level, imply that the whole plant can be thought of as a far-from-equilibrium hierarchical system with continuous mechanical coupling (Kasprowicz et al 2011). Such systems are known to exhibit complex mechanical behavior and are very sensitive to external influences, in particular, due to signal-amplifying force transfer through specific mechanically prestressed pathways (Ingber 2003).…”

Plants operate with tensional and compressive stresses that are extreme by animal standards. These stresses vary sharply on sub-and supracellular scales, but are orchestrated at the organismal level and evolve in a well-defined way during morphogenetic events. Plant morphogenesis is accomplished by localized and anisotropic yielding of cell walls that accommodate turgor-driven extension without losing mechanical integrity. Plant cell walls are connected cohesively into a stressallocating network enabling mechanical forces to be efficiently transmitted and serve as a long-distance messenger that plays an important integrative and regulatory role. Mechanical forces control the dynamics of both cortical microtubules and phytohormone auxin transporters, the two key players in guiding plant morphogenesis. The onset of organogenetic events in shoots and roots is associated with stereotypical changes in the pattern of tissue stresses. Initiation of leaves, lateral roots, and root hairs can be rationalized within the framework of the concept of stress hyperrestoration.
