Abstract

Modifications of cell-wall polysaccharides during stipe elongation in were investigated by gel-filtration and Smith-degradation analyses. During stipe elongation two polysaccharide fractions (I and IVa) decreased in average molecular weight, whereas two other fractions (II and III) increased marginally in molecular weight. The decreases in molecular weight of the former fractions were accompanied by changes in glycosidic linkage composition. Glucans comprised the bulk of all fractions; additionally there was an appreciable contribution from mannose and xylose in fraction II. The results are discussed in relation to the mechanisms of stipe elongation.
