    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract Plants produce 180 billion tons of cellulose per year, which has enormous commercial value in, for instance, wood. Cellulose microfibrils are crystalline aggregates of linear polymers of Dglucopyranosyl residues, linked in the beta-(1,4) conformation. The architecture of microfibrils is cell type and developmental stage specific, and a determinant of mechanical wall properties. Using a systems biology approach, we have formulated a theory explaining how cells can determine microfibril angle. This fully mathematical developmental model quantitatively relates the deposition angle of CMFs to (1) the density of active synthases in the plasma membrane (N), (2) the distance between individual microfibrils within a wall lamella (d) and (3) the geometry of the cell (D). The model constructs all textures and predicts them, if [N], [d], and [D] are known. By predicting texture when a parameter is altered, the model is a design tool for production of plants with desirable traits
