Abstract
- The time course of sulfate uptake in relation to respiration is shown for aging slices of potato, Solanum tuberosum L. cv. Russet. For comparative purposes, a time course for phosphate uptake is also shown. Malonic acid depressed both the respiratory rise and the sulfate accumulating ability of aging discs. A low dose of ultraviolet radiation given at the onset of aging reduced sulfate uptake by oneāhalf without lowering respiration. We hypothesize that sulfate uptake is controlled by at least two mechanisms: one associated with oxidative metabolism and the other mediated by protein synthesis [ABSTRACT FROM AUTHOR]
