A mechanism for lignification in plants
Carbohydrate Polymers, 1990Abstract The mechanism of lignification is explained in terms of a free radical formation after abstraction of phenolic hydrogen from coniferyl alcohol. In plants this oxidative reaction occurs in the presence of a hydrogen peroxide-peroxidase system.

Journal of Theoretical Biology, 1985
According to the author's proposed mechanism of lignification in plants, a further approach by physico-chemical theory, mostly the result of LCAO-MO manipulation, depicts the appropriate mechanism scheme and also describes the various linkages and formations in lignin structure.

Molecular Biology of Lignification in Grasses
2012As we transition into the twenty-first century, the need for renewable resources to address global energy and food demands has become a major concern. Around the world, scientists are interested in engineering dedicated biomass feedstocks particularly for improved cell wall composition by modifying the major wall components, cellulose and lignin.

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 ...

Lignification: Flexibility, Biosynthesis and Regulation
Trends in Plant Science, 2016Lignin is a complex phenolic polymer that is deposited in the secondary cell wall of all vascular plants. The evolution of lignin is considered to be a critical event during vascular plant development, because lignin provides mechanical strength, rigidity, and hydrophobicity to secondary cell walls to allow plants to grow tall and transport water and ...

TORUS LIGNIFICATION IN HARDWOODS
IAWA Journal, 2004Tori in wood of Osmanthus americanus, Daphne odora, Celtis occidentalis and Ulmus alata were tested for lignins using KMnO4 staining in conjunction with TEM, and acriflavine staining in concert with CLSM. It was hypothesized that impregnation with lignin could explain torus survival during cytoplasmic apoptosis.

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.

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.

NONENZYMATIC LIGNIFICATION OF ASPARAGUS?
Journal of Texture Studies, 1987ABSTRACTThe hypothesis of nonenzymatic lignification was investigated in asparagus. Samples were stored within 2 h of harvesting at 22C, 4C and ‐ IOC and tested daily, every second day and at 30‐day intervals, respectively. Some asparagus was blanched at IOOC for 3 min prior to storage.

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.
