Electric potential differences in bean roots and their relation to salt uptake.
Reversible diffusion of KGl is shown to occur between an aqueous solution and young bean roots, probably in the protoplasmic phase. Evidence for this is presented from a study of electric potential difference (p.d.) changes and changes in environmental salt concentration in different samples but under comparable conditions. Characteristic changes of p.d. with time are obtained when a root tip t...
متن کاملEssential Arginyl Residues in the Plasma Membrane H + - ATPase from Vigna radiata L . ( Mung Bean ) Roots '
Proton-translocating ATPase (H+-ATPase) was purified from mung bean (Vigna radiata L.) roots. Treatment of this enzyme with the argininespecific reagent 2,3-butanedione in the presence of borate at 37°C (pH 7.0), caused a marked decrease in its activity. Under this condition, halfmaximal inhibition was brought about by 20 millimolar 2,3-butanedione at 12 minutes. MgATP and MgADP, the physiologi...

متن کاملThe biocontrol potential of Pseudomonas fluorescens against Macrophomina phaseolina and estimating the total phenol compounds of bean roots
Charcoal rot caused by Macrophomina phaseolina is one of the most important soil borne diseases with a broad host range including bean, which annually brings a significant damage to this plant. Biological control of charcoal rot is very important because its chemical control harms the environment, microflora and soil fertility. Chemical control of charcoal rot is also difficult and sometimes in...
متن کاملRelationship between Growth and Electric Oscillations in Bean Roots.
Extracellular and intracellular electric potentials in bean roots are known to show electric oscillations along the longitudinal axis with a period of several minutes. The relationship between growth and the electric oscillations was studied using roots of adzuki (Phaseolus chrysanthos). We measured surface electric potentials with a multielectrode apparatus while simultaneously measuring elong...
