The evolutionary success of land plants was fostered by the acquisition of the xylem vascular tissue which conducts water and minerals upwards from the roots. The xylem tissue of flowering plants is composed of three main types of cells: the sap-conducting tracheary elements (TE), the fibres which provide mechanical support and the parenchyma cells which provide metabolic support to the tissue. Both the TEs and the fibres deposit thick polysaccharidic secondary cell walls (SCWs), reinforced by a rigid phenolic polymer called lignin. The cell walls of TEs form efficient water conducting hollow

The plant primary cell wall is a three-dimensional interwoven network of cellulose microfibrils, cross-linked by xyloglucan and dispersed in a pectin matrix. It has been suggested that in the wall of growing plant cells, xyloglucan is bound to the rigid cellulose microfibrils by hydrogen bonds and holds the microfibrils together by forming molecular tethers, which is referred to as the ‘sticky network’ model. Plant growth occurs when these tethers are peeled from the microfibrils by expansins or broken by glycosidases or transglycosylases. A number of researchers have presented theoretical dif

Comparative work on the structure of the cell walls of red kidney bean hypocotyls and mesocarp from unripe and ripe mango fruits showed significant differences. Cell-wall fractions from each were obtained using solvent extraction (water, alkali and acid) and enzymic (endopolygalacturonase) degradation procedures. The monosaccharide composition of each fraction was determined after TFA-hydrolysis by TLC-analysis. Greatest variation in monosaccharide compositions was observed in the water-soluble fractions which accounted for 18%, 48% and 11% of the cell walls of the bean, unripe and ripe mango,

Lignin, one of the three main components of the secondary cell wall, is an important phenolic biopolymer that provides strength and rigidity to the cell walls of tracheary elements and fibers in vascular plants. Lignin is composed of phenolic alcohol monomers called monolignols, which are synthesized in the cytoplasm. These monolignols are exported to the apoplast where they polymerize by random radical coupling following oxidation by laccases and peroxidases. Two laccases found in Arabidopsis thaliana, LAC4 and LAC17, were localized to secondary cell wall, and required for lignification of pr

It is generally assumed that most of the nutrients contained in a food are released (bioaccessible) during digestion and potentially available for absorption. However, the structure of plant food such as almonds, in particular the cell walls (‘dietary fibre’), may encapsulate intracellular nutrients, thereby limiting their bioaccessibility. The main aim of the studies described in this thesis was to investigate the role played by almond cell walls in the regulation of lipid bioaccessibility and digestion kinetics using a combination of in vivo, in vitro and in silico methods.

This thesis examines the interaction of xyloglucan, the major hemicellulosic component of type I primary plant cell walls, with cellulose. Initial attempts to form xyloglucan-cellulose complexes by in vitro association methods are described, which gave low levels of interaction, with features not similar to those found in primary wall networks. The majority of the work focusses on the use of the bacterium Acetobacter aceti ssp. xylinum (ATCC 53524), which synthesise highly pure, crystalline cellulose as an extracellular polysaccharide. Addition of xyloglucan to a cellulose-synthesising bacteri

Thesis (PhD(Agric) (Horticulture))--University of Stellenbosch, 2011.<br>Includes bibliography.<br>ENGLISH ABSTRACT: Mealiness, a soft, dry textural disorder of ‘Forelle’ pear (Pyrus communis L.), is a problem for the South African fruit export industry. Soft, dry textural disorders seem to be related to changes in cell wall breakdown. The aim of this work was, therefore, to investigate the occurrence of mealiness‐associated changes in the cell wall and elucidate the mechanism by which mealiness occurs in ‘Forelle’ pear, as well as to characterise cell wall changes occurring during normal
