“…The values for the elastic moduli for the leaves given in table I are of the same order of magnitude as those reported for epidermal root cells of wheat by Frey-Wryssling (5 corresp)onlding to a w-ater potenitial of about -12 bars. The so-called l)erml1anent wilting p)henomenon is explainled in terms of the variation in elastic modtilts.…”

“…This indicates that cellulose II is the crystalline state of the in vitro product as it occurs in the assay mixture and that it is not a consequence of drying. Cellulose II has been reported to occur in the cell walls of the slime mold Dictyostelium, the fungus Oomyces, and the green alga Halicystis (34).…”

The cytoplasmic and outer membranes of Acetobacter xylinum (ATCC 53582) were isolated by discontinuous sucrose density ultracentrifugation. Both lysozyme (EC 3.2.1.17) and trypsin (EC 3.4.21.4) were required for efficient crude membrane separation. Primary dehydrogenases and NADH oxidase were used as cytoplasmic membrane markers, and 2-keto-3-deoxyoctulosonic acid was used to identify the outer membranes. Cellulose synthetase (UDP-glucose:1,4-(3-Dglucan 4-(3-D-glucosyltransferase; EC 2.4.1.12) activity was assayed as the conversion of radioactivity from UDP-['4C]glucose into an alkali-insoluble P-1,4-D-[14C]glucan. This activity was predominantly found in the cytoplasmic membrane. The cellulose nature of the product was demonstrated by (i) enzymatic hydrolysis followed by TLC, (ii) methylation analysis followed by TLC, and (iii) GC/MS. Further, the weightaverage and number-average degree of polymerization of the in vitro product, determined by high-performance gel permeation chromatography, were 4820 and 5270, respectively. In addition, x-ray diffraction analysis indicated that the in vitro product is cellulose II, which is in contrast to the in vivo product-namely, cellulose I.

“…For the mechanism of cell wall growth we may refer to MÜHLETHALER (1950) and FREY-WYSSLING (1950). MÜHLETHALER found that the individual cells of a coleoptile have inelastic centre parts and elastic poles, because secondary layers are absent at the tips of the cells only.…”
