Distribution of GO activity in segregating populations of maize plants grown from seeds of selfed mutant heterozygous plants with decreased GO activities

Plant MaterialGO Activitya
μmol glyoxylate formed (g fresh weight)−1 h−1
Low GO0.66 ± 0.08 (n = 39)
Intermediate GO2.86 ± 0.14 (n = 88)
Wild-type GO6.00 ± 0.30 (n = 65)
  • a GO activity was determined on extracts of leaf disks from plants grown in 1% to 5% CO2 in a chamber in a growth room as described in “Materials and Methods.” Samples were taken from 192 plants in seven separate growth experiments. The mean activity values are given ±se.
