摘要
Treatment of the xyloglucan isolated from the seeds of Hymenaea courbaril with Humicola insolens endo-1,4-beta-D-glucanase I produced xyloglucan oligosaccharides, which were then isolated and characterized. The two most abundant compounds were the heptasaccharide (XXXG) and the octasaccharide (XXLG), which were examined by reference to the biological activity of other structurally related xyloglucan compounds. The reduced oligomer (XXLGol) was shown to promote growth of wheat (Triticum aestivum) coleoptiles independently of the presence of 2,4-dichlorophenoxyacetic acid (2,4-D). In the presence of 2,4-D, XXLGol at nanomolar concentrations increased the auxin-induced response. It was found that XXLGol is a signaling molecule, since it has the ability to induce, at nanomolar concentrations, a rapid increase in an Lu-L-fucosidase response in suspended cells or protoplasts of Robes fruticosus L. and to modulate 2,4-D or gibberellic acid-induced alpha-L-fucosidase.
