polygalacturonate/ダイズ

Treatment of suspension-cultured Glycine max cv Harosoy 63 cells with soluble chitosan (20-500 micrograms per milliliter) increased membrane permeability as shown by leakage of electrolytes, protein, and UV absorbing material. Severe damage to the cell membrane by chitosan (100 and 500 mug/ml) was

We report the use of Ni(2+) and Co(2+) on free-hand sections of soybean (Glycine max L.) and Bidens sp to localize polygalacturonates. In soybean only the hourglass cells of the seedcoat stain intensely. In the pod the epidermis of the outer pod wall and a few layers of subepidermal cells stain

Treatment with chitosan of suspension-cultured Glycine max cells labeled with (45)Ca(2+) caused a rapid release of calcium, which was complete much earlier than the chitosan-induced leakage of intracellular electrolytes and probably reflects calcium loss primarily from the cell wall and/or plasma

Carbohydrate-hybridization probes (Vreeland and Laetsch, 1989, Planta (177, 423-434) were used to localize the homogalacturonan (pectate) component of pectins in the cell walls of leaves and soybean root nodules. Leaves of two species of the dicotyledon Dubautia were compared; these species contain
