The researchers studied how the activity of two important enzymes in pea plants' root nodules changes as the plants grow. They found that the enzyme glutamine synthetase was most active in young nodules, and its activity correlated with another enzyme called nitrogenase. However, the changes in glutamine synthetase activity throughout the day and night did not follow a clear pattern.
