Postillumination Respiration of Maize in Relation to Oxygen Concentration and Glycolic Acid Metabolism

Abstract

Prior illumination in CO2-free air enhances a respiration from maize (Zea mays L.) leaves different in onset and duration from the postillumination burst of photorespiration. The course of respiration after brief illumination of attached leaves was measured as CO2 efflux in darkness into CO2-free atmospheres with four O2 concentrations. The peak of CO2 efflux following illumination was suppressed by 2.23% O2, was completely eliminated by 0.04% O2, and was not stimulated by 40% O2 compared with air. Compared with air, steady dark respiration was suppressed by 0.04% O2 but was not affected by 2.23% nor 40% O2. Excision and subsequent uptake of distilled water through the vascular system nearly eliminated the enhanced respiration.

Several metabolites fed to excised leaves through the vascular system during illumination doubled or tripled the respiration of maize in darkness. The sensitivity to 2.23% O2 of the respiration of glycolic acid in the dark imitated the sensitivity to O2 of attached leaves.

The respiration of glycolic acid was inhibited by α-hydroxy-2-pyridinemethanesulfonate.

While attached leaves and leaves fed glycolic acid both released little CO2 into CO2-free air in bright light, declining illuminance caused a larger and prompter CO2 efflux from leaves fed glycolic acid than from attached leaves. Leaves fed glycolic acid plus 3-(p-chlorophenyl)-1, 1-dimethyl urea released more CO2 into CO2-free air in bright light than did controls fed glycolic acid.
