Hansen U, Tittor J, Gradmann D
J Membr Biol . 2015 Feb; 75(2):141-69. PMID: 25691374
The temporal behavior of current through a biological membrane can display more than one time constant. This study represents the reaction kinetic analysis of the nonsteady-state behavior of a class...

Tittor J, Hansen U, Gradmann D
J Membr Biol . 2015 Feb; 75(2):129-39. PMID: 25691373
Reaction kinetic analysis of the electrical properties of the electrogenic Cl(-) pump inAcetabularia has been extended from steady-state to nonsteady-state conditions: electrical frequency responses of theAcetabularia membrane have been measured...

Gradmann D
Planta . 2014 Feb; 93(4):323-53. PMID: 24496769
1. In sea water at 25°C cells of Acetabularia crenulata exhibit a resting potential (RP) of-170 mV between cytoplasm and external medium. At temperatures below 10°C, or upon addition of...

Gradmann D, MAYER W
Planta . 2014 Jan; 137(1):19-24. PMID: 24420512
The internal potential of flexor cells in slices of the laminar pulvini of Phaseolus coccineus has been recorded by standard microelectrode techniques in 100 eq m(-3) external salt solutions of...

Starrach N, Freudling C, MAYER W, Gradmann D
Planta . 2013 Nov; 160(1):88-90. PMID: 24258377
Studies using excised tissues usually suffer from a discrepancy in the results between freshly excised preparations and "aged" ones (i.e. preparations which are allowed to rest and-or regenerate for about...

Goldfarb V, Gradmann D
Plant Cell Rep . 2013 Nov; 2(3):152-5. PMID: 24257987
Partly purified membranes (with plasmalemma material) of Acetabularia mediterranea were studied with respect to ATPase activity in alkali- and Ca(++)-free media and its sensitivity to pH (5 - 9), oligomycin...
7.
Behrens H, Gradmann D, Sievers A
Planta . 2013 Nov; 163(4):463-72. PMID: 24249445
Membrane potentials were measured in lateral statocytes of vertically and nonvertically growing roots of Lepidium sativum L. using conventional glass-microelectrode techniques. Statocytes in vertically growing roots showed a stable resting...

Behrens H, Gradmann D
Planta . 2013 Nov; 163(4):453-62. PMID: 24249444
Electrical transmembrane potential differences and resistances in different tissues of intact root tips of Lepidium sativum L. were investigated in a humid atmosphere by conventional glass-microelectrode techniques with the reference...

Freudling C, Starrach N, Flach D, Gradmann D, MAYER W
Planta . 2013 Nov; 175(2):193-203. PMID: 24221712
The laminar pulvinus of primary leaves of Phaseolus coccineus L. was investigated with respect to the total K(+) content, the apoplastic K(+) content, and the water potential of extensor and...

Smahel M, Hamann A, Gradmann D
Planta . 2013 Nov; 181(4):496-504. PMID: 24196929
The prime plasmalemma ATPase of the halophilic green alga Dunaliella bioculata has been solubilized by Triton X-100 from a plasmalemma-rich membrane fraction and purified by anion-exchange chromatography. Vanadate-sensitive ATPase activity...
