Název v původním jazyce

Glutamate kinase as a potential biomarker of heavy metal stress in plants.

Popis výsledku v původním jazyce

Changes in metabolism of spinach (Spinacia oleracea L. cv. Matador) plants exposed to chronic stress caused by two heavy metals, cadmium and zinc, were studied. The activity of glutamate kinase was detected and its regulatory role in plant stress adaptation during the spinach growth period was investigated in two series of pot experiments. Results of the first experimental series revealed the toxic effects of cadmium and zinc at all tested levels (30, 60, 90 mg Cd and 250, 500, 750 mg Zn . kg-1soil) forspinach. Under these conditions, a significant decrease of glutamate kinase activity in spinach plants grown on contaminated treatments compared to untreated control was found. Changes of glutamate kinase activity of spinach plants grown on Cd3 or Zn3 treatments in the second series of experiments showed a similar course as a curve of plant stress response indicating the process of plant adaptation to chronic stresses. In summary, changes of glutamate kinase activity in spinach plants u
