15 gru 2023 · Growing plant cells assemble a strong yet extensible nanofibrillar structure on their surface, the primary cell wall, which physically limits cell growth and defines cell size and shape.
Identifying the proteins that are required for biosynthesis of major cell wall components, including cellulose, hemicellulose, pectin, and lignin, is an essential step in uncovering plant cell wall structure and function.
1 sty 1991 · Throughout its life, the cell wall provides the plant with the mechanical strength to construct and protect itself against the environment. The cell wall can be divided into primary and secondary cell walls.
The plant cell wall is a rigid but highly dynamic structure that provides mechanical support, protection against pathogen attack, and determines the direction and extent of cell expansion ( Humphrey et al., 2007 ).
30 kwi 2010 · We also touch on an exciting emerging role of the cell wall–plasma membrane–cytoskeleton continuum as a signal perception and transduction pathway allowing plant growth regulation in response to endogenous and exogenous cues.
11 wrz 2017 · Plants are able to generate large leaf surfaces that act as two-dimensional solar panels with a minimum investment in building material, thanks to a hydrostatic skeleton. This requires high intracellular pressures (up to 1 MPa), which depend on the presence of strong cell walls.
It is increasingly clear that cell walls within an organ appear to be mosaics of complex heterogeneous architectures and the goal is to describe and to understand this macromolecular patterning and what the structural features of specific polysaccharides impart to each cell wall or cell wall region.
