Activity of nitrate reductase (NR), nitrite reductase (NiR), glutamine synthetase (GS), glutamate synthase (GOGAT) and glutamate dehydrogenase (NADPH-GDH and NADH-GDH) of 7-day-old B. juncea L. roots after treatment with PEG (10%) and its combination with NO (100 µM) and ABA (10 µM) (nitrate agonists) for 96 h. Values are mean ± S.E. of three independent experiments, each including four biological replicates. Asterisk (*) indicates significant difference compared with control (*p < 0.05).
