Fig. 4

Effects of mutations in the PB1 domain on steady-state transcript levels from nitrate-inducible genes. a After germination, seedlings were grown on 0.5× MS agar plates for 4 days and then transferred to agar plates containing 10 mM KNO3 as a nitrogen source for 5 days. Transcript levels were normalized against UBQ10 expression. Data are means ± SD (n = 3). Asterisks indicate significant differences versus Col by one-way ANOVA with Dunnett’s post hoc test for multiple comparisons; *: P < 0.05, **: P < 0.01, and ***: P < 0.001. b Correlations between NLP7 and NIA1 expression. Error bars are SD. The slopes for the wild-type and mutated NLP7 differ significantly by analysis of covariance (P < 0.05)
