N2  - The effects of  NO3- nutrition on iron deficiency responses were investigated in  Arabidopsis thaliana. Plants were grown with or without 5 µM Fe, and with  NO3- alone or a mixture of NO3- and NH4+. The results indicated that,  NO3- nutrition induced higher dry matter production, regardless  the  Fe  concentration.  Fe  deficiency  reduced  growth  activity,  photosynthetic pigment concentration and Fe content of plants, whatever the N forms.  This decrease was more pronounced in plants grown with mixed N source; those plants presented the highest EL and MDA and anthocyanin contents compared to plants grown under Fe sufficient conditions. In iron free-solutions, with NO3- as the sole nitrogen source, enhanced FC-R activity in the roots was observed. However, in the presence of NH4+, plants displayed some decrease in in FC-R and PEPC activities. The presence of NH4+ modified typical Fe stress responses in Arabidopsis thaliana plants.
