Identifying candidate genes/loci influencing barley secondary cell wall properties
The 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 …

Structural colour from a helicoidal cellulose architecture in the secondary cell wall: Optical properties, cell wall composition, structure and morphology of components, and their assembly and interactions.
… structural coloration consists of assembling cellulose microfibrils into helicoidal structures. Examples of these architectures can be found in phylogenetically distant species and in different tissues of plants, such as in the endocarp of the fruit of $\textit{Margaritaria nobilis}$, an …

Glucuronic Acid Patterning on Xylan in Arabidopsis thaliana
… this biomass comes from the polysaccharide-rich secondary cell wall. Industrially, polysaccharides have a number of potential key uses. For these to be possible, it is important to understand how polysaccharides are synthesised and arranged to confer structural properties to the cell wall. The …

Functional characterization of NAC-domain transcription factors implicated in control of vascular cell differentiation in Arabidopsis and Populus
… renewable raw material. The composition of xylem cell types in wood determines the utility of different types of wood for distinct commercial applications. Using expression profiling and phylogenetic analysis, we identified many xylem-associated regulatory genes that may control the …

A sorghum NAC gene is associated with variation in vascular development, biomass properties, and yield potential
… The building blocks of the vascular system are secondary cell walls, which make up the majority of plant biomass. Understanding the gene regulatory network underlying secondary cell wall synthesis can improve the understanding of vascular development and yield and ultimately benefit future …

New molecular mechanisms of Arabidopsis thaliana resistance to necrotrophic pathogens = New molecular mechanisms of Arabidopsis thaliana resistance to necrotrophic pathogens
… Thus, we have demonstrated that A. thaliana secondary cell wall is not just a structural defensive barrier, but is also an important component of specific signalling in defence responses. The broad spectrum resistance of irx1 and irx5 mutants, impaired in the Cellulose Synthases (CESAs) …

Advancing characterization techniques for structure-property determination of in-situ lignocelluloses
… analytical tools to understand and optimize lignocellulosic biomass utilization. In an effort to advance lignocellulose characterization, gain insights into biomass processing, and obtain novel perspectives on cell wall ultrastructure, this study utilizes three principal polymer characterization …

Genetic mapping and molecular characterization of tbr1 mutant in Arabidopsis thaliana
… under polarized light, a characteristic of cell walls containing large amounts of highly ordered cellulose microfibrils. The tbr1 mutant of Arabidopsis lacks trichome birefringence and is deficient in secondary cell wall cellulose synthesis (Potikha and Delmer, 1995). The TBR gene was …

Identifying and characterizing genes that regulate vascular tissue-specific functions
… support to the plant body and the conducting cells for the transport of water, mineral solutes, hormones and other signaling molecules, amino acids, and sugars. To identify genes that may regulate vascular tissue-specific functions, we isolated xylem, phloem-cambium, and nonvascular tissues …

Design characterisation and in planta expression of a chimeric xylanase
The recalcitrance of lignocellulosic biomass to enzymic digestion remains a significant obstacle to the adoption of an environmentally and economically sustainable strategy for the synthesis of biomaterials. Traditional industrial pre-treatments are harsh, require significant investments of energy …

Functional analysis of Poplar genes regulating flowering and vegetative growth
… and PopNAC156, co-orthologs of Arabidopsis SECONDARY CELL WALL NAC DOMAIN2 (SND2), which are putative regulators of wood cell wall synthesis, the source of lignocellulosic biomass. Second, I studied PopCEN1, PopCEN2, and PopBFT, members of the TERMINAL FLOWER1 (TFL1)/CENTRORADIALIS (CEN) …

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 …

Carbohydrate-Interacting Proteins from Two Nostoc (Cyanobacteria) Species
… that are responsible for producing the extracellular polysaccharide (EPS) of Nostoc commune DRH1, ultimately to allow the transfer of this capacity to another organism. Two artificial substrates were synthesized for use in a capillary electrophoresis-based enzyme assay, which was used to look …

Genome editing for engineering resilience to climate changes in grapevine
… angle and root length. Interestingly, the secondary roots of the mutants were quantitatively less than those of the WT, but had a larger diameter, similar to that of the primary roots. In addition, grafting showed that the different root phenotype of Kober epfl9-2 KO persisted even in the …

Discovery of New Protein-DNA and Protein-Protein Interactions Associated With Wood Development in Populus trichocarpa
… involved in lignin biosynthesis, programmed cell death, and cambial zone associated TFs. The promoters were screened against a mini-library composed of TFs expressed 4-fold or higher in differentiating xylem vs phloem-cambium. The Y1H results identified PtrRAD1 with interactions involving …
