Reorganization of Protein Tyrosine Nitration Pattern Indicates the Relative Tolerance of (L.) over (L.) to Combined Heavy Metal Treatment.

Metal-polluted areas, especially where municipal sewage is used as fertilizer, often have high concentrations of more than one metal. The development of the root system is regulated by a complex signaling network, which includes reactive oxygen and nitrogen species. The delicate balance of the endogenous signal system can be affected by various environmental stimuli including heavy metals (HMs) in excess.
