Characterization of novel genetic alleles of cellulose synthase
Cellulose is the most abundant polymer on earth. Despite this, relatively little is known about the proteins and biochemical mechanisms governing cellulose biosynthesis. Only in the past 10 years since the sequencing of the Arabidopsis thaliana genome have we begun to unravel the full complexity of …

Defining the role of cellulose synthase-like M genes in the plant cell wall
… to understand the role of genes of interest. The cellulose synthase-like M (CslM) subfamily is the latest identified member of the CesA superfamily. There are now 10 cellulose synthase-like subfamilies in plants with many of them implicated in the biosynthesis of the backbones of non-cellulosic …

Developing bioinformatic tools for phosphorylation site co-regulation and correlation: The plant Cellulose Synthase Complex as a case study
Cellulose is the most abundant biopolymer on the planet, and this paracrystalline polysaccharide has a variety of industrial applications ranging from textiles to biofuel production. Regulation and polymerization of cellulose in plant cell walls are complex pathways consisting of many proteins with …

Characterization of the expression patterns of <i>CELLULOSE SYNTHASE-LIKE A (CSLA)</i> genes in <i>arabidopsis thaliana</i> using reporter promoter-fusions and immunolocalization
… communication. This study is focused on the <i>CELLULOSE SYNTHASELIKE A (CSLA)</i> family, members of which have been implicated in the synthesis of the backbone of mannan polysaccharides in plant cell walls. The Arabidopsis genome contains nine <i>CSLA</i> genes and we hypothesize that there is …

Post-translational phosphorylation dynamics in Arabidopsis and Physcomitrella
… the phospho-regulation of the Arabidopsis plant cellulose synthase complex and cellulose synthase-like proteins. Chapter Three discusses protein-protein complex dynamics in the model moss plant Physcomitrella patens. This chapter demonstrates that Physcomitrella convergently evolved to contain …

Identification of novel components that connect cellulose synthases to the cytoskeleton
Cellulose is the most abundant biopolymer on earth and the main load-bearing structure in plant cell walls. Cellulose microfibrils are laid down in a tight parallel array, surrounding plant cells like a corset. Orientation of microfibrils determines the direction of growth by directing turgor …

Forward and reverse genetic approaches to investigate cellulose biosynthesis in Physcomitrium patens
Cellulose biosynthesis is a common feature of land plants and involves multimeric complexes composed of cellulose synthase A (CESA) proteins and other structural proteins. The exact stoichiometry of CESA proteins and interactions among proteins within cellulose synthase complex (CSC) is not well …

Evolutionary and functional study of plant cell wall polysaccharide glucomannan
… 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 (β-galactoglucomannan) exist?”. The results suggest that β-GGM is likely to be specific to dicots and …

Identification of genes involved in (1,3;1,4)-β-glucan synthesis in barley (<i>Hordeum vulgare</i>)
… in (1,3;1,4)-β-glucan biosynthesis is Cellulose synthase-like F6 (CslF6), but many aspects of the biosynthesis remain unclear. Using the barley Morex genome sequence assembly, new genes of the CslF family (HvCslF11 and HvCslF12) were identified and tested for a potential function in …

Regulation of (1,3;1,4)-β-Glucan Synthesis in Barley (<i>Hordeum vulgare</i> L.)
… Previous research identified members of the Cellulose synthase-like HvCslF/H gene families as (1,3;1,4)-β-glucan synthases differentially expressed across barley tissues (Burton et al., 2006; Doblin et al., 2009). Amongst them, HvCslF6 is thought to be the main driver of (1,3;1,4)-β-glucan …

Genetic mapping and molecular characterization of tbr1 mutant in Arabidopsis thaliana
… 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 identified by recombinational mapping, candidate gene …

Elucidating the roles of the diguanylate cyclases CelR and avmA in attachment and cellulose synthesis with the response regulator divK in Agrobacterium tumefaciens
… of this interaction involves the production of cellulose fibrils by the bacteria, leading to the aggregation of the cells to each other as well as to the plant surface. While this interaction between the bacteria and plants has been partially characterized, little is known concerning the …

Integrative high-throughput analyses of aerial morphodynamics in plants
… of POM2/CSI1, a linker protein between cellulose synthase complexes and microtubules, is conducted. Methods from the above projects are integrated to assess phenotypes in mutant plants relative to wild-type both at cell and tissue scales. It is found that plants with defective POM2/CSI1 …

Metalloenzymes required for glycan processing and morphological development in Streptomyces lividans
… of a glycan by GlxA produced by CslA (a cellulose-synthase), required for morphogenesis on solid and liquid cultures. The molecular nature of this glycan is unknown. A number of GlxA variants were created in Chapter 3 to elucidate the proteins unique spectroscopic properties. It was found …
