The plant cell wall is composed of multiple biopolymers, representing one of the most
complex structural networks in nature. Hundreds of genes are involved in building such a …

This article recounts, from my perspective of four decades in this field, evolving paradigms of
primary cell wall structure and the mechanism of surface enlargement of growing cell walls …

Plant stature and development are governed by cell proliferation and directed cell growth.
These parameters are determined largely by cell wall characteristics. Cellulose microfibrils …

Highlights•Cellulose interactions with the matrix depend on microfibril shape.•Physical data
point to a microfibril made of 18–24 chains, not 36 chains.•Recent structures for cellulose …

Secondary walls are mainly composed of cellulose, hemicelluloses (xylan and
glucomannan) and lignin, and are deposited in some specialized cells, such as tracheary …

Abstract Background Secondary cell walls (SCWs) form the architecture of terrestrial plant
biomass. They reinforce tracheary elements and strengthen fibres to permit upright growth …

The walls surrounding the cells of all land-based plants provide mechanical support
essential for growth and development as well as protection from adverse environmental …

All plant cells are surrounded by a cell wall that determines the directionality of cell growth
and protects the cell against its environment. Plant cell walls are comprised primarily of …

In the primary walls of growing plant cells, the glucose polymer cellulose is assembled into
long microfibrils a few nanometers in diameter. The rigidity and orientation of these …
