| Description
| - Changes of glutamate kinase activity (GKA) in plants under cadmium and zinc chronic stress reported here reveal a regulatory role of this enzyme in plant heavy metal stress adaptation and indicate its potential use as a stress biomarker. Results of the first experimental series confirmed the toxic effects of cadmium and zinc at tested levels (30, 60, 90 mg Cd kg1 and 250, 500, 750 mg Zn kg1 soil) for spinach. A significant decrease of GKA in plants grown on contaminated treatments was found. Changes of GKA of plants grown on the highest contaminated 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—the decline of GKA in period of damage of cell activities, increase of its activity in period of maximum resistance and its following decrease in period of the plant metabolism depletion.

- V rostlinách špenátu byly popsány změny aktivity glutamátkinázy (GK) v průběhu stresové reakce vyvolané zvýšenou koncentrací kadmia nebo zinku v půdě. Změny aktivity GK odpovídaly klasickému schématu průběhu stresové reakce u rostlin s nárůstem v období maximální rezistence a poklesy během fáze počátečního narušení buněčných struktur a funkcí (poplachová fáze) a během fáze vyčerpání. Získané výsledky poukázaly na uplatnění GK při adaptaci rostlin na stres způsobený těžkými kovy a naznačily možné využití toho enzymu jako stresového biomarkeru. (cs)
