Abstract

The oligosaccharide glycans mannosylalpha1-6(mannosylalpha1-3)mannosylalpha1-6(mannosylalpha1-3) mannosylbeta1-4-N-acetylglucosamine and mannosylalpha1-6(mannosylalpha1-3)(xylosylbeta1-2) mannosylbeta1-4-N-acetylglucosaminyl(fucosylalpha1-3) N-acetylglucosamine were infiltrated into mature green tomato fruit (Lycopersicon esculentum Mill., cv Rutgers). Coinfiltration of 1 nanogram per gram fresh weight of the glycans with 40 micrograms per gram fresh weight galactose, a level of galactose insufficient to promote ripening, stimulated ripening as measured by red coloration and ethylene production.
