Expansive 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...

How 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...

Dimensional Analysis of Expansive Growth of Cells with Walls

Expansive growth is central to development, morphogenesis, and sensory responses of algal, fungal and plant cells. These walled cells generate turgor pressure by absorbing water. The turgor pressure produces irreversible (plastic) and reversible (elastic) deformations in a wall whose mechanical properties are regulated biochemically. These biophysical processes (water uptake and wall deformatio...

The Favorite Point of a Poisson Process

In this paper we consider the most visited site, Xt, of a Poisson process up to time t. Our point of departure from the literature on maximal spacings is our asymptotic analysis of where the maximal spacing occurs (i.e., the size of Xt) and not the size of the spacings.

Navigation on a Poisson Point Process

On a locally finite point set, a navigation defines a path through the point set from a point to another. The set of paths leading to a given point defines a tree, the navigation tree. In this article, we analyze the properties of the navigation tree when the point set is a Poisson point process on R. We examine the local weak convergence of the navigation tree, the asymptotic average of a func...
