Iron Reduction by Sunflower Roots under Iron Stress
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.
