Ligninbiosynthese
Lignin biosynthesis begins in the cytosol with the synthesis of glycosylated monolignols from the amino acid phenylalanine. These first reactions are shared with the phenylpropanoid pathway. The attached glucose renders them water-soluble and less toxic. Once transported through the cell membrane to the apoplast, the glucose is removed, and the polymerisation commences. Much … Nettet1. apr. 2011 · Identification of cis-regulatory elements in most of the monolignol biosynthesis pathway genes has paved the way towards understanding the transcriptional regulation of lignin biosynthesis.Detailed promoter and electrophoretic mobility shift assay (EMSA) analysis has revealed that the AC-rich elements corresponding to the …
