Resumen:
Iron is an essential micronutrient required for a wide variety of
cellular functions in plant growth and development. Chlorosis is the
first visible symptom in iron deficient plants. As a consequence,
cellular redox homeostasis is disturbed due mainly to the
diminished photosynthetic activity. Both ascorbate (Asc) and
glutathione (GSH) are multifunctional metabolites that are
important in redox balancing. We were interested in studying the
effect of Asc and GSH during iron deficiency in Arabidopsis plants.
Either, Asc or GSH prevented the chlorosis in iron deficient plants
without involving changes in hydrogen peroxide content, a ROS
suspected to increase during iron deficiency stress
