Modulation of Copper Uptake and Toxicity by Abiotic Stresses in Matricaria chamomilla Plants

Popis výsledku v původním jazyce

The impact of salinity (S) or nitrogen deficiency (-N) on copper (Cu) uptake and changes to metabolism were studied in the combined treatments after 7 days of exposure. S suppressed growth, water content, soluble proteins, and reducing sugars more negatively than -N. ROS (hydrogen peroxide and superoxide) were differentially but relatively slightly affected while peroxidase activities were strongly elevated mainly in Cu+NaCl variant. Total soluble phenols and individual phenolic acids (free and cell wall-bound fraction) were accumulated the most in Cu-N while, among free amino acids, proline sharply increased in Cu+NaCl; this suggests a compensatory mechanism between the syntheses of antioxidants aimed to maintain antioxidative protection because numerous root phenolic acids were even depressed by S. Salinity also suppressed accumulation of coumarin herniarin, but its glucosidic precursors ((Z)- and (E)-2-beta-D-glucopyranosyloxy-4-methoxycinnamic acids) increased. Activities of select
