Resumen:
Iron is an esential element for plants. In Arabidopsis thaliana, iron
uptake depends on the reduction of Fe3+ to Fe2+ and the
internalization of Fe2+. These actions are carried out by a Fe3+
internalization of Fe2+. These actions are carried out by a Fe3+
internalization of Fe2+. These actions are carried out by a Fe3+

reductase, (FRO), and an iron transporter (IRT), respectively.
Expression of IRT1 and FRO2 are regulated by the transcription
factor FIT1. When iron is not available for growth, reactive oxygen
species (ROS) and nitric oxide (NO) levels increase, as well as FRO,
IRT and FIT expression. To evaluate the role that NO might have in
the activation of plant responses to iron deficiency in A. thaliana,
plants grown in iron deficient conditions were treated with the NO
scavenger methylene blue (MB) and the nitrate reductase (NR)
inhibitor tungstate (Tg). NR is a NO producing enzyme in plants.
Seedlings growing with low iron supply showed symptoms of
chlorosis.
