Abstract

Under iron deficiency stress several dicotyledonous species (sunflower, bean, cucumber, etc.) develop in their roots morphological and physiological changes in order to increase iron uptake: root tips swelling, increase in the ferric reducing capacity (RC), proton efflux, and release of phenolic compounds. In this work we present the response to iron stress of a Fe-efficient inbred line (RHA 274) and the effect of an inhibitor of polar auxin transport 2,3,5-triiodobenzoic acid (TIBA) on the iron stress response.
