The cell biology of lignification in higher plants - PMC
网页2015年4月15日 · Lignin (Latin lignum ‘wood’) is a polyphenolic polymer deposited directly in the cell wall of specialized cells. It is not only restricted to plant woody tissues but represents an integral feature ensuring the proper cellular function of many other cell types in different tissues/organs of the plant.
Lignification: Flexibility, Biosynthesis and Regulation
网页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 ….
Lignification - an overview | ScienceDirect Topics
网页Lignification is the process of polymerization of the monolignols, p-coumaryl, coniferyl and sinapyl alcohols, each giving rise to the hydroxyphenyl (H), guaiacyl (G) or syringyl (S) lignin units, respectively. From: Plant Physiology and Biochemistry, 2003
Lignification: Flexibility, Biosynthesis and Regulation
网页2016年8月1日 · Lignification is a complex process found only in higher plants, with the main functions to provide stability to the vascular part of the plant and form a barrier against microbial infections.
The regulation of cell wall lignification and lignin biosynthesis ...
网页2021年11月1日 · In this study, we investigated the regulation of cell wall lignification and lignin biosynthesis during pigmentation of winter jujube. The cellulose content decreased, while the lignin content ...
Lignins: Biosynthesis and Biological Functions in Plants
网页2018年1月24日 · Lignin is one of the main components of plant cell wall and it is a natural phenolic polymer with high molecular weight, complex composition and structure. Lignin biosynthesis extensively contributes to plant growth, tissue/organ development, lodging resistance and the responses to a variety of biotic and abiotic stresses. In the present review ...
Understanding Lignification: Challenges Beyond Monolignol …
网页2010年10月6日 · Lignin is a heterogeneous phenolic polymer largely composed of three major types of monomers (monolignols), p -coumaryl, coniferyl, and sinapyl alcohols. During lignin deposition, monolignols are synthesized in the cytoplasm, translocated to the apoplast, and polymerized into lignin.
cell biology of lignification in higher plants | Annals of Botany ...
网页2015年4月15日 · Cell wall lignification occurs during the differentiation of distinct cell types, but also in response to specific environmental changes. The appropriate timing and localization of lignin deposition in each distinct cell type is essential for the proper function and adaptation of plants to their environment.

网页Lignification is the process of polymerization of the monolignols, p -coumaryl, coniferyl and sinapyl alcohols, each giving rise to the hydroxyphenyl (H), guaiacyl (G) or syringyl (S) lignin units, respectively. Deposition of lignin in the cell wall occurs simultaneously as the polymer is …
Lignin: the Building Block of Defense Responses to Stress in Plants
网页2023年2月10日 · Lignin is a complex aromatic biopolymer important for providing mechanical strength to the cell wall and resistance against both biotic and abiotic stresses. It helps in plant growth by providing physical strength and helping in long distance transport of water and minerals.
