Lignification in Plant Cell Walls
1997Cell wall lignification is a complex process occurring exclusively in higher plants; its main function is to strengthen the plant vascular body. This process involves the deposition of ill-defined phenolic polymers, the so-called lignins, on the extracellular polysaccharidic matrix.

Lignification: different mechanisms for a versatile polymer
Current Opinion in Plant Biology, 2015Lignins are cell wall phenolic polymers resulting from monolignol radical coupling. They have characteristically high diversity in their structures which is a direct consequence of the versatile character of the lignification mechanisms discussed in this review.

An approach to lignification in plants
Biochemical and Biophysical Research Communications, 1982Abstract A lignin-like substance was synthesized in vitro from coniferyl alcohol in the presence of peroxidase with coenzymes NADH and flavin. Eugenol was also polymerized in the same way.

The Biochemistry of Lignification
1981Publisher Summary This chapter discusses briefly the occurrence and structure of the lignins found in higher plants. The pathways leading to lignin can be divided into several minor sequences. The first of these, the so-called “shikimic acid pathway” (which should properly be designated as the “chorismic acid pathway” according to its central ...

Exploring the plasticity of lignification
2021Lignin is a phenolic polymer found predominantly in the secondary cell walls of vascular plants where it contributes to water transport, mechanical support, and plant defence. The occurrence, composition, and structure of lignin vary widely between cell types, throughout development, in response to stress, and across plant lineages.

Trends in Plant Science, 1998
Lignins are phenolic polymers of the cell wall, and form the second most abundant group of plant biopolymers after cellulose. The application of molecular genetics and powerful analytical techniques means that a new view is required of the structure, biogenesis and location of these molecules.

Lignins and lignification: Selected issues
Plant Physiology and Biochemistry, 2000Lignin deposition in plant cell walls is one of the mechanisms which allowed the development of upright plants adapted to a terrestrial habitat. At the present time, lignins and lignification are the subject of very active research which has recently moved from chemical and biochemical aspects to more biological and developmental problems.

Lignification and lignin topochemistry — an ultrastructural view
Phytochemistry, 2001This review discuses the ultrastructural aspects of cell wall lignification and lignin topochemistry. Lignification results from the enzyme mediated polymerization of monolignols initiated by unknown factors (initiation sites) located at the corners of cells and in the middle lamella.
