Summary
Maize internode cell wall development involves rapid secondary cell wall deposition and lignification before flowering. Post-flowering, slow deposition occurs with lignin rich in β-O-4 bonds and p-coumaroylation.
Area of Science:
- Plant Biology
- Biochemistry
- Agricultural Science
Background:
- Plant cell wall development is complex, with phenolic compounds limiting polysaccharide accessibility in grasses.
- Understanding cell wall composition is crucial for optimizing plant biomass utilization.
Purpose of the Study:
- To investigate cell wall development patterns in maize internodes across three genotypes.
- To analyze the spatiotemporal dynamics of lignification, p-coumaroylation, and feruloylation.
Main Methods:
- Combined biochemical assays and histological analyses.
- Examined cell wall composition and structure in maize internodes at different developmental stages.
Main Results:
- Rapid secondary cell wall deposition and lignification observed in pith and rind before flowering.
- Post-flowering, slow deposition in the cortical region with lignin rich in β-O-4 bonds and high p-coumaroylation.
Conclusions:
- Proposed a revised spatiotemporal model for grass cell wall development.
- Highlighted the distinct compositional changes during maize internode development.

The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

7.4K
Plant cells have a cell wall, a rigid outer covering that protects the cell and provides shape and support. During cell division, a mixture of enzymes, proteins, and glucose molecules is transported via vesicles to the center of the cell. These vesicles continuously fuse and build a cell plate between the dividing cells. As the cell plate matures, new polysaccharides are added to it to form the cell walls of the daughter cells. The predominant polysaccharide in the cell wall is cellulose, made...

2.2K
The bacterial cell wall is an essential structural component that encases the plasma membrane, preserving cellular integrity, determining shape, and protecting against osmotic stress. This rigid yet flexible structure primarily comprises peptidoglycan, a polymer that forms a mesh-like matrix conferring mechanical strength and flexibility.Peptidoglycan Composition and StructurePeptidoglycan, the core of the bacterial cell wall, comprises alternating units of N-acetylglucosamine (NAG) and...

1.0K
Archaeal cell walls are structurally and compositionally distinct from their bacterial counterparts, lacking the characteristic peptidoglycan layer found in most bacteria. Instead, archaeal cell walls exhibit remarkable diversity, utilizing materials such as pseudomurein, polysaccharides, and proteins to construct their protective outer layers. This structural flexibility is closely tied to archaea's ecological adaptability.S-Layers: The Common Archaeal Cell WallThe S-layer is the most...

01:02Role of Microtubules in Cell Wall Deposition
3.0K
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...

01:18Composite Masonry Walls
1.7K
Composite masonry walls combine multiple wythes of the same or different masonry materials to create a unified structure. These walls feature wythes that are bonded together either through mortar-filled collar joints, grouted spaces, or more commonly, with rigid metal ties and reinforcements, with the use of masonry header units being rare. Metal ties are preferred because they effectively minimize water penetration, as these walls primarily absorb moisture and then release it into the...
