tulipa luanica/carbohydrate

The uptake of glucose and other carbohydrates into the guard cells of Commelina communis L. was found to inhibit the opening of the stomata. The concentration of glucose necessary to achieve about 50% inhibition was of the same order of magnitude as the potassium concentration required for opening;

We developed capillary affinity electrophoresis (CAE) to analyze the molecular interaction between carbohydrate chains and proteins in solution state. A mixture of oligosaccharides derived from a glycoprotein was labeled with 8-aminopyrene-1,3,6-trisulfonate (APTS), and used as glycan library

The effect of a cold treatment on the carbohydrate status of the scales and flower stalk of Tulipa gesneriana L. cv Apeldoorn bulbs during growth after planting was studied and compared with bulbs not given cold treatment. Bulbs were stored dry for 12 weeks at 5[deg]C (precooled) or 17[deg]C

Isolated epidermis of Commelina communis L. and Tulipa gesneriana L. assimilated (14)CO2 into malic acid and its metabolites but not into sugars or their phosphates; epidermis could not reduce CO2 by photosynthesis and therefore must be heterotrophic (Raschke and Dittrich, 1977). If, however,
