Metabolism of [1-14C]glycolate by maize leaf discs in darkness in a segregating mutant population with varying GO activities

The mean GO activities assayed from leaf disc extracts are given for each plant material ±se (n = 5). Enzymatic 14CO2 production during the 2-h incubation is likewise reported as the corrected count rate (n = 3).
