New Type Plant Cellulose.

Cellulose in cyanobacteria. Origin of vascular plant cellulose synthase?

Although cellulose biosynthesis among the cyanobacteria has been suggested previously, we present the first conclusive evidence, to our knowledge, of the presence of cellulose in these organisms. Based on the results of x-ray diffraction, electron microscopy of microfibrils, and cellobiohydrolase I-gold labeling, we report the occurrence of cellulose biosynthesis in nine species representing th...

Cellulose: How many cellulose synthases to make a plant?

Many questions remain about the biosynthesis of cellulose, the major plant cell wall component, not least of which is why plants have so many genes for the cellulose synthase catalytic subunit. Perhaps multiple isoforms of cellulose synthase are needed in the same cell for the formation of functional dimeric complexes.

Characterization of Cellulose Synthesis in Plant Cells

Cellulose is the most significant structural component of plant cell wall. Cellulose, polysaccharide containing repeated unbranched β (1-4) D-glucose units, is synthesized at the plasma membrane by the cellulose synthase complex (CSC) from bacteria to plants. The CSC is involved in biosynthesis of cellulose microfibrils containing 18 cellulose synthase (CesA) proteins. Macrofibrils can be forme...

Trafficking of the plant cellulose synthase complex.

Cellulose synthase interacting protein: a new factor in cellulose synthesis.

Cellulose is the most abundant biopolymer on earth. The great abundance of cellulose places it at the forefront as a primary source of biomass for renewable biofuels. However, the knowledge of how plant cells make cellulose remains very rudimentary. Cellulose microfibrils are synthesized at the plasma membrane by hexameric protein complexes, also known as cellulose synthase complexes. The only ...
