Bioinspired lignocellulosic films to understand the mechanical properties of lignified plant cell walls at nanoscale
The physicochemical properties of plant fibres are determined by the fibre morphology and structural features of the cell wall, which is composed of three main layers that differ in chemical composition and architecture. This composition and hierarchical structure are responsible for many of the mechanical properties that are desirable for industrial applications. As interactions between the li...
متن کاملExpansive growth of plant cell walls.
The enlargement of plant cell walls is a key determinant of plant morphogenesis. Current models of the cell wall are reviewed with respect to their ability to account for the mechanism of cell wall enlargement. The concept of primary and secondary wall loosening agents is presented, and the possible roles of expansins, xyloglucan endotransglycosylase, endo-1,4-beta-D-glucanase, and wall synthes...
متن کاملDislocation-mediated growth of bacterial cell walls.
Recent experiments have illuminated a remarkable growth mechanism of rod-shaped bacteria: proteins associated with cell wall extension move at constant velocity in circles oriented approximately along the cell circumference [Garner EC, et al., (2011) Science 333:222-225], [Domínguez-Escobar J, et al. (2011) Science 333:225-228], [van Teeffelen S, et al. (2011) PNAS 108:15822-15827]. We view the...
متن کاملDiferulate Cross-Links Impede the Enzymatic Degradation of Non-Lignified Maize Walls
We assessed the e†ect of ferulate substitution and diferulate crosslinking of xylans on the degradation of cell walls by two fungal enzyme mixtures, one of which contained feruloyl esterase and high xylanase activities. NonligniÐed cell suspensions of maize (Zea mays) were grown with 0 or 40 lM 2aminoindan-2-phosphonic acid to produce walls with normal (17É2 mg g~1) or reduced (5É1 mg g~1) feru...
متن کاملHow do cell walls regulate plant growth?
The cell wall of growing plant tissues has frequently been interpreted in terms of inextensible cellulose microfibrils 'tethered' by hemicellulose polymers attached to the microfibril surface by hydrogen bonds, with growth occurring when tethers are broken or 'peeled' off the microfibril surface by expansins. This has sometimes been described as the 'sticky network' model. In this paper, a numb...
