123. Synopsis

The results of an investigation of the cell wall composition of Mougeotia have greatly aided our understanding of the phylogenetic relationships within the Charophyceae. A weakly crystalline cellulose fraction represented 13.5% of the Mougeotia mechanically isolated wall preparation. Cellulose I diffraction patterns were only evident following limited acid hydrolysis of a hot alkali insoluble fraction. It was concluded that the cellulose crystallites in the native state were too small to be detected without extensive extraction of other cell wall polysaccharides. Cellulose microfibril assembly in Mougeotia was observed to be associated with solitary rosette/globule terminal complexes. Similarities between the cell wall composition of Mougeotia and Klebsormidium suggest that their cellulose component is characteristic of cellulose soon after its evolution in the cell walls of algae representing the direct ancestors of vascular plants.
