The Mechanical Properties and Molecular Dynamics of Plant Cell Wall Polysaccharides Studied by Fourier-Transform Infrared Spectroscopy)

Polarized one- and two-dimensional infrared spectra were obtained from the epidermis of onion (Allium cepa) under hydrated and mechanically stressed conditions. By Fourier-transform infrared microspectroscopy, the orientation of macromolecules in single cell walls was determined. Cellulose and pectin exhibited little orientation in native epidermal ce...

Crop Science ; LIGNIN plays a vital role in plant growth and development by improving water conduction through xylem tracheary elements, enhancing the strength of fibrous tissues, and limiting the spread of pathogens in plant tissues (Iiyama et al., 1994). Lignin restricts the degradation of structural
Neural Network Analyses of Infrared Spectra for Classifying Cell Wall Architectures1[W][OA]
Plant Physiology ; About 10% of plant genomes are devoted to cell wall biogenesis. Our goal is to establish methodologies that identify and classify cell wall phenotypes of mutants on a genome-wide scale. Toward this goal, we have used a model system, the elongating maize (Zea mays) coleoptile system, in which cell
How the cell wall acquired a cellular context
Plant Physiology ; It seems that 25 years ago plant cell walls were different than they are now. I don't mean physically different, of course-they were made of the same old stuff-I mean conceptually different. Let me try to explain. Much of the plant body (and in large plants the bulk of it) is comprised of cell wall
Changes in cell wall polysaccharides of green bean pods during development
Plant Physiology ; The changes in cell wall polysaccharides and selected cell wall-- modifying enzymes were studied during the development of green bean (Phaseolus vulgaris L.) pods. An overall increase of cell wall material on a dry-weight basis was observed during pod development. Major changes were detected in the
