Plant cell wall polymers
WebJul 1, 1994 · Plant cell enlargement is controlled by the ability of the constraining cell wall to expand. This ability has been postulated to be under the control of polysaccharide hydrolases or transferases that weaken or rearrange the loadbearing polymeric networks in the wall. We recently identified a family of wall proteins, called expansins, that ...

WebMar 7, 2015 · Wood cell walls contain lignin, a phenolic polymer, up to approximately 32% of cell wall dry material. Lignin is, after cellulose, the second most abundant biopolymer on earth, and it plays a crucial role for structural integrity of cell walls and for stiffness and strength of the plant body. WebAlthough plant cell wall composition can greatly affect plant mechanical strength (Tanaka et al. 2003, Wang et al. 2024, Zhang and Zhou 2011), little is known about the exact functions of three major wall polymers (cellulose, hemicelluloses and lignin) in lodging resistance in rice (Halpin et al. 1998, Ma 2009).
