Absorption of polyethylene glycol by young bean and cotton plants. Measurement by gas chromatography in stem exudates


, : Absorption of polyethylene glycol by young bean and cotton plants. Measurement by gas chromatography in stem exudates. Comptes Rendus Hebdomadaires des Seances de l' Academie des Sciences, France, D 280(20): 2333-2336

In plants of Phaseolus vulgaris and cotton grown for 4-48 h in nutrient solutions with polyethylene glycol (PEG) with a molecular weight of 400 to give an osmotic potential of -2 atm, measurements of PEG in stem exudates showed that PEG was readily absorbed and translocated in appreciable quantities to the stem and leaves.

In the present study we demonstrated Jurkat leukemia cell lines of TIB152 and TIB153 with different sensitivities to recombinant soluble TRAIL cytotoxicity. TRAIL receptor death receptor 5 (DR5) was constitutively localized in the rafts in both ce...

Bovine serum albumin (BSA)-dextran conjugates were prepared by using the Maillard reaction; depending on the ratio of dextran to BSA used, about 0.5-1 mol of dextran could be bound to 1 mol of native BSA. SDS-PAGE patterns revealed that BSA and de...

Seven healthy native goats in early lactation, weighing 30-40 kg, were used in this study. The right mammary gland of the seven does were infused with CpG-ODN at a dosage of 100 microg kg(-1) body weight on the day 5 postpartum (PP). The left glan...
