Helicoidal cell walls are characterized by an oscillatory shift in the arrangement of cellulose microfibrils somewhat reminiscent of the rotating movement of the hands of a clock. The periodic movement can be sustained or perturbed. Thus, the helicoidal cell wall presents a temporal reading. Sensitive to temporal signals, the cell wall keeps a reco...

The development of suberin lamellae in the hypodermis of Zea mays cv. LG 11 was observed by electron microscopy and the presence of suberin inferred from autoliuorescence and by Sudan black B staining in nodal (adventitious) and primary (seminal) root axes. Suberin lamellae were evident at a distance of 30-50 mm from the tip of roots growing at 20°...

A benchtop assay based upon digestion of purified Escherichia coli peptidoglycan suspended in an agarose gel matrix is described. Enzymes for which these cell walls are substrates are applied to wells in the gel and diffuse into the gel. Activity is measured visually by the size of clear disks formed around the wells as the peptidoglycan is digeste...
The purpose of this investigation was to study the microbiological degradation of the cellulose-hemicellulose-lignin complexes of the faeces of pigs. Cellulose, hemicellulose and lignin are components of the cell wall of plants and residues of plant material occur in large quantities in faeces and other organic waste material. The development of th...
