Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants. [1] Lignins are particularly important in the formation of cell walls , especially in wood and bark , because they lend rigidity and do not rot easily.

In the present review, we systematically introduce the biosynthesis of lignin and its regulation by genetic modification and summarize the main biological functions of lignin in plants and their applications.

2024年12月27日 · The lignin adds compressive strength and stiffness to the plant cell wall and is believed to have played a role in the evolution of terrestrial plants by helping them withstand the compressive forces of gravity.

2018年3月29日 · Lignin is an alkyl-aromatic polymer found in the cell walls of terrestrial plants. Lignin provides structure and rigidity to plants, is a natural, highly effective barrier against microbial attack, and enables water and nutrient transport through plant tissues.

2018年9月27日 · In plants, there are two major steps to produce lignin: monolignol biosynthesis and monolignol polymerization via free radical coupling. Enzymes catalyzing monolignol biosynthesis have been well defined in the model plant Arabidopsis.

2018年1月24日 · In the present review, we systematically introduce the biosynthesis of lignin and its regulation by genetic modification and summarize the main biological functions of lignin in plants and their applications.

Lignin has a crucial role in plant growth and development; it exhibits ubiquitous synthesis in the middle and later stages of plant development. Also, lignin’s synthesis is inducible upon pathogen invasion in the specific tissues which confer resistance to associated pathogens.

Lignified cell types in higher plants. The role of lignin: as a transport barrier; in water and nutrient transport; for mechanical support; for seed protection and dispersion; and as a response to biotic and abiotic factors. Tracheary elements (TEs)

2008年1月1日 · Lignin is one of the most predominant biopolymers present in plants. Together with cellulose and hemicelluloses, lignin builds up the cell wall in an arrangement which is regulated on the nano-scale and results in lignin–carbohydrate network structures.
