  • This article summarizes the theory and practical aspects of measuring cell wall properties by four different extensometer techniques and how the results of these methods relate to the concept and ideal measurement of cell wall extensibility in the context of cell growth. These in vivo techniques are particularly useful for studies of the molecular basis of cell wall extension. Measurements of breaking strength, elastic compliance, and plastic compliance may be informative about changes in cell wall structure, whereas measurements of wall stress relaxation and creep are sensitive to both changes in wall structure and wall-loosening processes, such as those mediatedmore » by expansins and some lytic enzymes. A combination of methods is needed to obtain a broader view of cell wall behavior and properties connected with the concept of cell wall extensibility.« less
  • The isolation, purification, and partial characterization of a glucuronoarabinoxylan, a previously unobserved component of the primary cell walls of dicotyledonous plants, are described. The glucuronoarabinoxylan constitutes approximately 5% of the primary walls of suspension-cultured sycamore cells. This glucuronoarabinoxylan possesses many of the structural characteristics of analogous polysaccharides that have been isolated from the primary and secondary cell walls of monocots as well as from the secondary cell walls of dicots. The glucuronoarabinoxylan of primary dicot cell walls has a linear ..beta..-1,4-linked D-xylopyranosyl backbone with both neutral and acidic sidechains attached at intervals along its length. The acidic sidechains are terminatedmore » with glucuronosyl or 4-O-methyl glucuronosyl residues, whereas the neutral sidechains are composed of arabinosyl and/or xylosyl residues.« less
  • Wild type Bacillus subtilis, when grown on a soybean arabinan-galactan, secretes a ..beta..-1,4-galactanase which has been purified more than 200-fold from the culture fluid. Affinity chromatography was the most effective step in a purification procedure which resulted in a preparation that contained only a single 40,000 molecular weight protein band upon sodium dodecyl sulfate-disc gel electrophoresis. The purified galactanase digests a ..beta..-1,4-galactan purified from citrus pectin and digests partially the isolated cell walls of suspension-cultured sycamore cells. The predominant product of the enzymic degradation of the substrates tested is a 4-linked tetragalactose. Evidence is presented to support the hypothesis thatmore » the galactanase attacks its substrates in both an exo- and endo-manner. The products obtained upon galactanase digestion of the soybean arabinan-galactan demonstrate that the earlier proposal concerning the structure of this polysaccharide must be incorrect.« less
