Accumulation of Arginine in Plants Afflicted with Iron-Deficiency Type Chlorosis

Abstract
Chlorotic and green blue-berry, apple, and magnolia leaves were fractionated, and the free amino acids were identified by paper chromatography. Data show that an accumulation of free arginine is characteristic of the nitrogen metabolism of plants affected with iron-deficiency chlorosis. It disappears during recovery from chlorosis. Other amino acids identified in these analyses are listed.
