Lignin and cellulose

NettetLignin is the second most naturally abundant biopolymer in the cell wall of lignocellulosic compound (15-35%) after cellulose.Lignin can be generated in massive amounts as by-products in biorefineries and pulp and paper industries through differing processes. Nettet9. apr. 2024 · PbrMYB132 activated the expression of gene encoding cellulose synthase (PbrCESA4b/7a/8a) and lignin laccase (PbrLAC5) binding to their promotors. As expected, overexpression or knockdown of PbrMYB132 increased or decreased stone cell content in pear fruit and SCW thickness in Arabidopsis transgenic plants.
