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.

摘要

寡糖糖蛋白甘露糖α1-6(甘露糖α1-3)甘露糖α1-6(甘露糖α1-3)甘露糖β1-4-N-乙酰葡萄糖胺和甘露糖α1-6(甘露糖α1-3)(木糖β1-2)甘露糖β1-4-N-乙酰葡萄糖胺被注入成熟的绿番茄果实(Lycopersicon esculentum Mill.,cv Rutgers)中。每克新鲜重量的聚糖与每克新鲜重量的半乳糖 40 微克共渗,半乳糖的水平不足以促进成熟,以红色着色和乙烯生成来衡量,刺激了成熟。
