Black soybeans (Glycine max (L.) Merr.) have been widely used as a health food and medicinal herb in oriental medicine. In the present study, the chemical structures of two water-soluble polysaccharides (black soybean polysaccharide 1 (BSPS-1) and black soybean polysaccharide 3 (BSPS-3)) isolated
Stem parasitic plants (Cuscuta spp.) develop a specialized organ called a haustorium to penetrate their hosts' stem tissues. To reach the vascular tissues of the host plant, the haustorium needs to overcome the physical barrier of the cell wall, and the parasite-host interaction via the cell wall is
In soybean (Glycine max (L.) Merr.) root nodules the level of hydroxyproline-containing molecules is developmentally regulated. Hydroxyproline accumulates in both nodule cortex and medulla. In the cortex, the hydroxyproline is mainly localized in the cell wall, presumably as extensin, but in the
The mist culture system was conducted to study secreted polysaccharides from soybean ( Glycine max) roots grown for 15 days. Roots were rinsed with distilled water (DW) for 15 min, then with 30 mM oxalic acid (OXA) for 15 min to remove ionically bound sugar. Released sugars were further fractionated
