Opis:: The stable EPR signal produced by ionizing radiation in crystalline D-mannose (C6H12O6) and separated from cranberries (Vaccinium oxycoccus) was studied. The isothermal heating of irradiated sample at 95°C for 10 minutes (melting point of D-mannose is 132°C) resulted in the modifi cation and simplifi cation of the EPR signal involved. The isotropic quartet has been recognized in the EPR signal of heat-treated sample. Molecular structure of the isotropic quartet identifi ed in the complex EPR signal of D-mannose crystallite is proposed.

Opis:: The effect of mannose on nitrate uptake was investigated by a new non-invasive technique. Under normal condition, nitrate uptake by wheat (Triticum aestivum L.) roots was about 1-7 µmol gfwt-1 h-1. After the addition of 10 mM mannose, net nitrate influx by wheat roots started to decrease and reached a new steady state at -40 ±50% of the control value after 73 min. After mannose supplied for 2 h, its removal caused net nitrate influx to be recovered to an original rate. Therefore, the inhibition of mannose on nitrate uptake is not due to the onset of programmed cell death because it starts too rapidly and it is reversible, however, it is probably due to Pi and consequent ATP depletion.

Opis:: Radicals produced by ionizing radiation in sugars, the components of dried and raw fruits give rise to stable multicomponent electron paramagnetic resonance (EPR) signals unidentified so far. The subject of the present EPR study is to identify the radicals stabilized in gamma-irradiated crystalline sugars, D(+)mannose and L(-)sorbose extracted from cranberries (Vaccininum oxycoccos) and rowan berries (Sorbus aucuparia), respectively. EPR measurements and density functional theory (DFT) simulations were employed for that purpose.
