Reducing cell wall recalcitrance in poplar through overexpression of cell wall degrading enzymes
<p>Abundant cellulose in the secondary cell walls of lignocellulosic biomass provides an alternative source of carbohydrates for ethanol production. However, low efficiency and high cost of conversion of cellulose to glucose prevents the large-scale production of economically viable cellulosic …

Kiwifruit softening: A cell wall study
Cell walls are important for providing structural integrity to fruit tissues during softening. While there are reports on changes relating to fruit softening in kiwifruit cell walls, this study was the first to examine two closely related genotypes of Actinidia chinensis with different softening …

Characterizing the role of central carbon metabolism and cell wall stress responses in Bacillus subtilis cell wall synthesis
The cell wall is an essential organelle for many bacteria since it provides mechanical strength and prevents bacterial cell lysis due to internal turgor pressure. Additionally, the cell wall is the first line of defense against various external stresses. The mesh of peptidoglycan is a major …

Wood cell wall modification with hydrophobic molecules
… is used for many applications because of its excellent mechanical properties, relative abundance and as it is a renewable resource. However, its wider utilization as an engineering material is limited because it swells and shrinks upon moisture changes and is susceptible to degradation by …

On the Gram-positive bacterial cell wall.
Cell wall is the outermost part of Gram-positive bacteria. It is intricately tied to the bacteria's response to environmental stimuli and challenges, and its makeup dynamically changes as a part of bacterial adaptation. Peptidoglycan is the biopolymer that composes nearly half of the cell wall, and …

Molecular interactions of plant cell wall polymers
Specialised plant cells produce thickened cell walls, called secondary cell walls comprised of lignocellulose. The main polymers in lignocellulose are cellulose, xylan, galactoglucomannan and lignin. Lignocellulose forms the majority of biomass on the planet and its utilization for construction, …

Xylan chain length and plant cell wall assembly
The plant cell wall is a structure surrounding plant cells to serve signalling, developmental, and structural functions. In woody tissues, the cell wall is composed of cellulose (40-60%), lignin (20-30%), and hemicelluloses (20-30%). The plant cell wall is the largest source of renewable carbon …

On the Recalcitrant Nature of Sphagnum's Cell Wall
… this peat consists of undecomposed Sphagnum moss cell wall materials, prompting the proposal that this genus sequesters more carbon than any other plant. The extraordinary recalcitrance of Sphagnum’s cell wall is central both to the long term persistence of this carbon store and its capacity to …

Integrative analysis of heterogeneous plant cell wall related data
Plant cell walls are complex structures that underpin plant growth and are widely exploited in diverse human activities thus placing them with a central importance in biology. Cell walls have been a prominent area of research for a long time, but the chemical complexity and diversity of cell walls …

Cell Wall Lipids Promoting Host Angiogenesis During Mycobacterial Infection
… leads to the formation of characteristic immune cell aggregates called granulomas. In humans and animal models, tuberculous granuloma formation is accompanied by dramatic remodeling of host vasculature which ultimately benefits the infecting mycobacteria, suggesting the bacteria may actively …

Barriers to tuberculosis drug discovery: the mycobacterial cell wall
The mycobacterial cell wall is a highly complex macromolecular structure that provides intrinsic resistance to several anti-tuberculosis drugs, making it critical in the success of Mycobacterium tuberculosis infection. Multiple layers encapsulate the cell membrane, including arabinogalactan chains …

Yeast cell wall proteomics: a tale of two proteins.
This thesis investigates cell wall proteins, the presence of which increased in concentration as a result of stress. Two such proteins were found, phosphoglycerate mutase and Hsp 12. Studies on these proteins are reported in chapters 2 (phosphoglycerate mutase) and chapter 3 (Hsp 12).

Bio-based composites that mimic the plant cell wall
… of the most significant materials is the plant cell wall. The plant cell wall is a composite of oriented cellulose microfibrils reinforcing a lignin/hemicellulose matrix. In principle, the plant cell wall composite is designed much like a synthetic fiber-reinforced polymer composite. Unlike …

Identifying candidate genes/loci influencing barley secondary cell wall properties
… structure and composition of the secondary plant cell wall determine its digestibility and therefore on the efficiency of conversion of plant biomass for biofuel production. Bioethanol, a form of biofuel, refers to ethanol generated by fermentation of sugars extracted from plants. Second …

Evolutionary and functional study of plant cell wall polysaccharide glucomannan
My PhD thesis focused on the cell wall polysaccharide mannan; I investigated the function, evolution, and mutant phenotypes of its synthase. The main chapter consists of three independent parts. Chapter2 addresses the question, “In which group of evolutionary stages does β-GGM …
