✦ Synopsis
Phytoalexin-elicitor activity was reported for the oligogalactosiduronic acids 1 (n = 7-13) obtained either by partial hydrolysis of soybean cell-walls and citrus pectin2 with acid, or by digestion of polygalacturonic acid with endopolygalacturonanase of Rhizopus stolonifeti, and also for cr-(1+4)-linked decagalactosiduronic acid 2 carrying an unsaturated galacturonic acid residue at the nonreducing end (obtained from soybean cell-walls by treatment with an endo-a-l ,6polygalacturonic acid lyase of the bacterium Erwiniu carotovoru4. Oligogalactosiduronic acids of undetermined chain-length were also reported to function as messenger HO HO n = 7-13 C02H HO *Part 3 in the series "Synthetic Studies on Plant Cell-Wall Glycans".
