Abstract excerpt
Based on sequence analysis, the salt overly sensitive (SOS1) gene has been suggested to function as a Na(+)/H(+) antiporter located at the plasma membrane of plant cells, being expressed mostly in the meristem zone of the root and in the parenchyma cells surrounding the vascular tissue of the stem. In this study, we compared net H(+) and Ca(2+) fluxes and intracellular pH and [Ca(2+)](cyt) in the root meristem...
