Detailed explanation-1: -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.
Detailed explanation-2: -As a complex phenolic polymer, lignin enhances plant cell wall rigidity, hydrophobic properties and promotes minerals transport through the vascular bundles in plant [13]. In addition, lignin is an important barrier that protects against pests and pathogens [14].
Detailed explanation-3: -Lignin is an organic substance belonging to a group of aromatic alcohols. It is naturally produced by certain plants (especially woody plants and certain algal species). It is found in the secondary cell walls of plants where it serves as a binder for cellulose fibers and provides stiffness to the cell walls.
