Iron Content and Ferritin in Leaves of Iron Treated Xanthium pensylvanicum Plants 1

RESUMO
Iron administration to iron-starved cocklebur (Xanthium pensylvanicum) plants causes an increase in the iron content of ferritin fractions extracted from mature leaves. Xanthium plants grown under long days (vegetative stage) have more iron and ferritin than similarly iron-treated plants induced to flower under short day regimes. This first demonstration of ferritin in cocklebur (Compositae) leaves suggests that a substantial portion of iron that enters the iron-starved plant appears as this protein-iron macromolecule.
