[Characterization of the proteins involved in the transport and storage of iron in plants].

Iron is a transient metal essential for the proper growth and development of plants because as a component of the enzymes with a wide redox potential, iron contributes to the key cellular processes. During evolution, plants have developed a wide range of molecular mechanisms for the efficient control of iron homeostasis within their cells, tissues and organs. These include membrane proteins involved in the uptake, long-distance transport and intracellular distribution of iron as well as the iron-storing and iron-chelating proteins, that are involved in the protection of the plant cells from iron excess and/or ensure the proper growth and development of plants under Fe deficiency.
