Niflumic Acid Is Transiently Effective in Inhibiting Cryptogein-Induced NO₃⁻ Efflux.

Niflumic acid was added to tobacco cell suspensions 10 min before cryptogein. External medium aliquots were taken at the times indicated. NO₃⁻ content was determined using a colorimetric assay. Open circles indicate control cells; open squares indicate control cells treated with 200 μM niflumic acid; closed circles indicate cells treated with 25 nM cryptogein; and closed squares indicate cells treated with 25 nM cryptogein and 200 μM niflumic acid. The data are representative of five experiments. FW, fresh weight.
