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.
This Review describes the physics of wall growth and its regulation by cellular processes such as cellulose production by cellulose synthase, modulation of wall pH by plasma membrane H + -ATPase, wall loosening by expansin and signalling by plant hormones such as auxin and brassinosteroid.
Plant cells build nanofibrillar walls that are central to plant growth, morphogenesis and mechanics. Starting from simple sugars, three groups of polysaccharides, namely, cellulose,...
The plant cell wall is a natural nanoscale network structure that primarily consists of polysaccharide polymers such as cellulose, hemicellulose, and pectin, but often includes glycoproteins and lignin as well.
The plant cell wall is an elaborate extracellular matrix that encloses each cell in a plant. It was the thick cell walls of cork, visible in a primitive microscope, that in 1663 enabled Robert Hooke to distinguish and name cells for the first time.
1 lut 2024 · We predict the next century of progress will include deciphering cell type–specific wall polymers; regulation at all levels of polymer production, crosslinks, and architecture; and how walls respond to developmental and environmental signals to drive plant success in diverse environments.
6 paź 2010 · Plant cell walls are usually divided in textbooks into two categories: primary walls that surround growing cells or cells capable of growth and secondary walls that are thickened structures containing lignin and surrounding specialized cells such as vessel elements or fiber cells.
