Mathematical Estimation of Endogenous Proline as a Bioindicator to Regulate the Stress of Trivalent Chromium on Rice Plants Grown in Different Nitrogenous Conditions.

ABSTRACT: The accumulation of proline impacts the defense mechanisms of plants against the harmful effects of adverse environmental conditions; however, its concentration in plants is associated with the metabolism of N. Therefore, the effects of exogenous organic [glutamate (Glu)/arginine (Arg)] and inorganic [nitrate (NO₃^-)/ammonium (NH₄⁺)] N on the accumulation of proline (Pro) in rice plants under trivalent chromium [Cr(III)] stress were studied through using the mass balance matrix model (MBMM). Application of 'NH₄⁺' showed the largest contribution to the Pro content in rice shoots under different concentrations of Cr(III), followed by 'NO₃^-', 'Arg', and 'Glu' applications. On the other hand, 'Arg' applicati
