Summary
Cell wall construction relies on endomembrane trafficking. This review details how vesicles transport polysaccharides and enzymes, highlighting unknown mechanisms in cell wall component delivery.
Area of Science:
- Plant Biology
- Cell Biology
- Biochemistry
Background:
- The cell wall provides structural support and protection.
- Cell wall biosynthesis is well-studied, but component transport remains unclear.
Purpose of the Study:
- To review endomembrane trafficking pathways in cell wall deposition.
- To identify knowledge gaps in the transport of cell wall components.
Main Methods:
- Literature review of endomembrane trafficking.
- Discussion of vesicle transport mechanisms.
- Exploration of emerging technologies like chemical genomics and proteomics.
Main Results:
- Cellulose synthase complexes move via vesicles from the Golgi to the plasma membrane.
- Non-cellulosic polysaccharides are synthesized in the Golgi.
- Cellulose is synthesized at the plasma membrane.
- Distinct vesicles transport cell wall modifying enzymes, but sorting mechanisms are unknown.
Conclusions:
- The endomembrane system is crucial for delivering cell wall components.
- The precise nature, composition, and timing of vesicle delivery are largely unknown.
- Advanced technologies may elucidate cell wall component trafficking.

02:43Plant Cell Wall
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.
01:07Plant Cell Wall
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...
01:26Transport Across the Golgi
While it is unclear how molecules move between adjacent Golgi cisternae, it is apparent that the molecules move from cis- cisterna, the entry face, to the trans- cisterna, the exit face. Experiments initially suggested vesicles that bud from one cisterna and fuse with the next cisterna to transport proteins between the cisternae. This vesicular transport model describes the Golgi apparatus as a relatively static structure with a unique enzyme composition in each cisterna. Molecules are...
01:49Golgi Apparatus
As they leave the Endoplasmic Reticulum (ER), properly folded and assembled proteins are selectively packaged into vesicles. These vesicles are transported by microtubule-based motor proteins and fuse together to form vesicular tubular clusters, subsequently arriving at the Golgi apparatus, a eukaryotic endomembrane organelle that often has a distinctive ribbon-like appearance.
01:09Golgi Apparatus
Properly folded and assembled proteins are selectively packaged into vesicles that exit the ER. Motor proteins transport these vesicles to the Golgi apparatus for adding modifications that make these proteins functional at their destination.
The Golgi apparatus is a eukaryotic organelle that has a distinctive ribbon-like appearance. It is a primary sorting and dispatch station for cargo arriving from the ER. Newly arriving vesicles enter the cis face of the Golgi, closest to the ER, and are...
