l-Malate as an Essential Component of the Xylem Fluid of Corn Seedling Roots
Corn seedling xylem exudate has a pH of 5.30 ± 0.05 due to the presence of 10 millimolar malate which has a pK(a) of 5.13. This concentration of malate tends to buffer the xylem fluid at this pH. Exogenous treatment of corn seedling roots with CaCl(2) caused a concentration-dependent decrease in the...
