4.2.2.23	rhamnogalacturonan I	(GR)n oligomers, where n = 7, 8 or 9, prelabeled with fluorescent 8-aminopyrene-1,3,6-trisulfonic acid, trisodium salt tags are injected into the intercellular spaces in cotton cotyledons, degradation of the oligomers is observed by capillary zone electrophoresis. Rhamnogalacturonan lyase products are identified as such by co-migration with the digestion products of linear rhamnogalacturonan oligomers when the oligomers are treated with fungal RG lyase but not when treated with fungal rhamnogalacturonan hydrolase	Gossypium hirsutum	rhamnogalacturonan I oligosaccharides with alpha-L-rhamnopyranose at the reducing end and 4-deoxy-4,5-unsaturated D-galactopyranosyluronic acid at the nonreducing end	-	?
