agriculture | main reason for iron deficiency chlorosis of plants grown on calcareous soils is the inhibition of FeIII reduction in the apoplast and hence Fe2+ uptake into the cytosol | Helianthus annuus |

high pH sensitivity of enzyme, highest activity at apoplastic pH of 4.9, no activity above apoplastic pH of 5.3. Nitrate increases pH value, thus inhibiting enzyme activity, ammonium decreases pH value. Nitrate together with hydrogen carbonate, a combination typical for calcareous soils, has strongest enzyme depressing effect | Helianthus annuus |
