Effect of urea treatment on biomass production of Arabidopsis plants grown on 0.5 mM urea. Arabidopsis plants were grown on sterile half strength MS medium supplemented with 1 μM NiCl2 and 50 μM NO3- plus 0.5 mM urea as sole N sources (same growth conditions described for Figure 6b). The fresh weights of 14 plants were measured after 16 days. Data are mean ±SD of three independent experiments and different letters above the bars indicate statistically significant differences (ANOVA, Student-Newman-Keuls, P < 0.05, n=3).
