Iron is a major constituent of the earth crust. However, under
alkaline conditions commonly found in arid and semi-arid
environments iron becomes unavailable to plants. When plants are
affected by a shortage of iron their leaves become yellow
(chlorotic), and both plant growth and crop yield are reduced. The
roots of plants affected by iron deficiency may develop a series of
responses directed to improve iron uptake, such as increased proton
excretion and iron reduction capabilities or excretion of iron
chela tors called siderophores. Iron deficiency affects major crops
worldwide, including some of major economic importance such as
fruit trees and others. Correction of iron deficiency is usually
implemented through costly application of synthetic chelates. Since
these correction methods are very expensive, the competitivity of
farmers is often reduced and iron deficiency may become a limiting
factor for the maintenance, introduction or expansion of some
crops. In spite of the many years devoted to the study of iron
deficiency, the knowledge of iron deficiency in soils and plants is
still fragmentary in many aspects. We have only incomplete
information on the processes at the molecular level that make some
plant species and cultivars unable to take and utilize iron from
the soil, whereas other plants grow satisfactorily under the same
conditions.
