Time course of the effect of SNP on nitrate reductase protein content in roots of tomato. Two-week-old seedlings were grown with 0·5 mm (A) and 5 mm (B) nitrate for 2 weeks, and were then transferred to the nutrient solution without or with 5 µm SNP under continuous light conditions. Nitrate reductase protein content was measured with ELISA at 1·5, 3, 6, 12 and 24 h after treatment. Error bars represent the s.d. (n = 6); no significant differences from the control were observed.
