Fig. 1From: Glutamine rapidly induces the expression of key transcription factor genes involved in nitrogen and stress responses in rice rootsEffects of glutamine on the growth of rice seedlings. a 17-day-old rice seedlings grown in hydroponic solutions containing NH4NO3 or glutamine as the nitrogen source. Shoot length (b), root length (c), and chlorophyll contents (d) of 17-day-old rice seedlings grown in different concentrations of glutamine. Data are means ± SD (n = 40). Different letters indicate significant differences between treatments, tested by one-way ANOVA followed by Tukey’s test (P < 0.05). +N, + 1.43 mM NH4NO3; −N, no nitrogenBack to article page
