Abstract
The regulation of carbonic anhydrase (CA) activity in maize (Zea mays L.) leaves by light and nitrogen nutrition was determined. CA activity increased by more than 100-fold in illuminated leaves and decreased in leaves placed in the dark; low levels of CA activity were observed in leaves illuminated with low light intensities. CA activity was reduced in plants grown under nitrogen deficiency and recovered only slowly when supplemented with nitrate. Parallel studies were conducted to follow the levels of phosphoenolpyruvate carboxylase. Experiments indicate that the level of CA and phosphoenolpyruvate carboxylase present in leaves may be controlled by similar mechanisms.Entities:
