Active H+ Efflux from Cells of Low-salt Barley Roots during Salt Accumulation

M G Pitman a,1
PMCID: PMC396512  PMID: 16657392

Abstract

Measurements were made of net H+ loss from low-salt barley roots accumulating salt. Comparison of rates of loss from roots in different concentrations of KCl showed that H+ loss increased in the same way as the Mechanism II component of salt uptake. This H+ loss appeared to be coupled to salt uptake and was not due to increased respiration or metabolic breakdown of sugars. In view of the large negative potential of the cells (−60 millivolts), it is suggested that the H+ loss is due to an outward proton transport process.
