Peptidoglycan is a large polymer that forms a mesh-like scaffold around the bacterial cytoplasmic membrane. Peptidoglycan synthesis is vital at several stages of the bacterial cell cycle: for expansion of the scaffold during cell elongation and for formation of a septum during cell division.
However, the plant cell wall is the least understood cellular structure in plants. Due to great progress in plant functional genomics, many achievements have been made in uncovering cell wall biosynthesis, assembly, and architecture, as well as cell wall regulation and signaling.

Their data suggest that cellulose microfibrils in plant primary walls must be sufficiently large to contain at least 24 chains. Moving from the primary cell wall, Kumar et al. (2016) provide a comprehensive review on secondary cell walls.
Jan 1, 2024 · Bacteria utilize a unique carrier lipid, undecaprenol phosphate (C 55-P, also called bactoprenol), for the synthesis of extracellular cell wall polymers, including peptidoglycan, teichoic acids and capsular polysaccharide [63].
Oct 6, 2021 · Cell division and expansion are two primary generators of plant biomass. As a major component of primary cell walls, cellulose is the most abundant biopolymer on the planet. In addition to global biomass, production and modification of the cell wall is vital to plants.
The plant cell wall is an elaborate extracellular matrix that encloses each cell in a plant. It was the thick cell walls of cork, visible in a primitive microscope, that in 1663 enabled Robert Hooke to distinguish and name cells for the first time.
Oct 6, 2010 · Because of their surface location, plant cell walls play an important role in plant-microbe interactions, including defense responses against potential pathogens. The desire to understand these and other plant functions help explain the strong interest in wall structure and biosynthesis.
