Physiological and molecular facets of plant iron nutrition and interactions in global scenario

Elucidation of physiological and molecular facets of iron
(Fe) nutrition and interactions in plants is essential for
development of sustainable agricultural practices under iron
nutrition stress. Iron interactions with zinc, nitrogen, boron,
aluminium and vanadium in important agricultural crops were
encouraging. Subsequently, considerable progress were made
towards the explanation of the roles of transport proteins
in plant Fe homeostasis. Iron in symplast is reduced to Fe2+,
mainly by the action of FROproteins, whereas FDR3 gene has an
important role in transporting Fe. Likewise, Strategy I confirms
that Fe3+ reduced by Ferric Reduction Oxidase 2 (FRO2) at
plasma membrane before transport across the membrane by
Iron-Regulated Transporter 1 (IRT1). The emerging physiological
andmolecular understandings of Fe uptake and translocation in
grains also indicate accumulation of some toxic metals, which
needs clarifications. Besides these, plant leaves are important
sink tissue for iron in plastids and mitochondria for numerous
enzymes and indispensable for photosynthesis and other
cellular metabolic processes. Investigations exhibited that
Fe deficiency inhibits symbiotic nitrogen fixation by affecting
growth and survival of rhizobial species, nodule formation
and nodule function, for Fe2+ being part of nitrogenase,
leghaemoglobin and ferredoxin regulated by nodulin-like
genes. Phaseolus vulgaris revealed significant roles of Fe in
host-rhizobiumassociation. Amazing roles of 24-Epibrassinolide
was recently evaluated inmaintaining physiologically active iron
besides seed loading, stored in vacuoles or in ferritin of many
crop species. Under changing climate, greater insights needs
to be derived for enhancing judicious use and efficiency of
iron in plants through sensible researches at molecular levels.
