Molecular Biology of Lignification in Grasses

2012
As 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

1981
Publisher 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, 2016
Lignin 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, 2004
Tori 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

2021
Lignin 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

1997
Cell 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, 1987
ABSTRACTThe 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.

Lignification: different mechanisms for a versatile polymer

Current Opinion in Plant Biology, 2015
Lignins 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.

A new view of lignification

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.
