Iron Deficiency and the Structure and Physiology of Maize Chloroplasts 1

PMCID: PMC541676  PMID: 16659137

Abstract

The ultrastructure of mesophyll chloroplasts of maize (Zea mays L.) was more severely affected by iron deficiency that induced mild chlorosis than was the ultrastructure of bundle sheath plastids. Ferredoxin and ribulose diphosphate carboxylase levels were severely decreased by iron deficiency. Malic enzyme was less affected, and phosphoenolpyruvate carboxylase activity remained high even under severe iron deficiency. Iron deficient leaves fixed carbon into malic and aspartic acids but the rate of entrance of carbon into the sugar phosphates and sucrose was greatly reduced compared to the control. Chlorophyll a/b ratios ranged from low values of less than 2 in severely iron deficient leaves to high values exceeding 4 in leaves showing little iron deficiency.
