Lignin is a major structural polymer of secondarily thickended plant vascular tissue and
fibres, imparting mechanical strength to stems and trunks and hydrophobicity to conducting …

An aspen lignin-specific O-methyltransferase (bi-OMT; S-adenosyl-l-methionine: caffeic
acid/5-hydroxyferulic acid 3/5-O-methyltransferase, EC 2.1. 1.68) antisense sequence in the …

Inhibition of specific lignin biosynthetic steps by antisense strategy has previously been
shown to alter lignin content and/or structure. In this work, homozygous tobacco (Nicotiana …

The monomeric composition of tobacco lignin has been modified by genetic engineering.
Sense or antisense expression of sequences encoding O‐methyltransferase (OMT), a lignin …

Using tobacco transgenic lines altered in the monolignol biosynthetic pathway and which
differ in their lignin profiles we have evaluated lignin deposition at the cellular and …

Transgenic tobacco (Nicotiana tabacum L.) plants in which the activity of 4-coumarate:
coenzyme A ligase is very low contain a novel lignin in their xylem. Details of changes in …

Among the different enzymatic steps leading to lignin biosynthesis, two methylation
reactions introduce the methyl groups borne by guaiacyl (G) and syringyl (S) units. Tobacco …

Homologous antisense constructs were used to down-regulate tobacco cinnamyl-alcohol
dehydrogenase (CAD; EC 1.1. 1.195) and cinnamoyl-CoA reductase (CCR; EC 1.2. 1.44) …

Xylem from stems of genetically manipulated tobacco plants which had had cinnamyl
alcohol dehydrogenase (CAD; EC 1.1. 1.195) activity down-regulated to a greater or lesser …

Transgenic alfalfa plants were generated harboring caffeic acid 3-O-methyltransferase
(COMT) and caffeoyl CoA 3-O-methyltransferase (CCOMT) cDNA sequences under control …
