A) Nitrate Reductase activity. B) Plant endogenous nitrite content. C) Plant total soluble proteins. Plants grew for seven days in simple Knop medium or media supplemented with increasing concentrations of sodium tungstate. Data are mean of three independent experiments. Data were analyzed by one-way ANOVA and Tukey´s multiple comparison test (n = 9 in panel A, n = 3 in panels B and C). Asterisk denotes statistically significant difference (P < 0.05). Error bars denote SE.
