Effect of soil humic substances on surface redox activity of oat roots
(1995)The effect of a low molecular weight (<5kDa, LMW) and a high molecular weight (>5kDa, HMW) humic fractions on surface redox activities of oat roots was studied. Oxidation of the electron donor NADH and reduction of the ... -
Plasma Membrane H+-ATPase in Maize Roots Induced for NO3- Uptake
(1995)Plasma membrane H+-ATPase was studied in maize (Zea mays L.) roots induced for NO3- uptake. Membrane vesicles were isolated by means of Suc density gradient from roots exposed for 24 h either to 1.5 mM NO3- or 1.5 mM SO4-. ...
