Gyunter, E. A. | Popeiko, O. V. | Ovodov, Yu. S.
Callus lines of common duckweed produced acid arabinogalactan and pectin in an amount varying from 1 to 3% of dry weight. The arabinogalactan specimens from the cell lines studied displayed a similar monosaccharide composition. The duckweed callus lines whose arabinogalactans contained apiose residues (1-2%) were found. All pectin specimens had a similar qualitative monosaccharide composition but differed in the quantitative content of monosaccharide residues. The lines with high contents of galactose, arabinose, and apiose in pectin specimens were obtained. The total content of neutral monosaccharide residues in pectins varied from 26 to 50%.
