Effects of glutamate on the expression of GDC1 and accumulation of GABA. qRT-PCR analysis of GDC1 from roots of 17-day-old rice seedlings treated with different concentrations of glutamate for 30 min (a), or treated with 2.5 mM glutamate for 0.25-24 h (b). Relative expression indicates the fold-change of each gene as compared to that of control. c The amounts of GABA in the roots. 17-day-old nitrogen-starved rice seedlings were transferred to hydroponics containing 2.5 mM glutamate for 24 h. The amounts of GABA in the roots were measured during the time course of glutamate treatments. Fold change indicates the relative amount of GABA compared to that of control (0 h). Data are means ± SD (n = 4). Different letters indicate significant differences between treatments, tested by one-way ANOVA followed by Tukey’s test (P < 0.05)
