Effects of NH4+ treatment on shoot NH4+ content and GS activity. (A) NH4+ contents in the shoot tissues of WT, ein3eil1, and amot1 seedlings. Five-day-old WT, ein3eil1, and amot1 seedlings were grown on growth medium and transferred to fresh medium with control or NH4+ for 3 d and 6 d of growth, and then NH4+ tissue content was determined. Values are means ±SD of three replicates. (B) NH4+ contents in the shoot tissues of WT and EIN3ox seedlings. Five-day-old WT and EIN3ox seedlings were grown on growth medium and transferred to fresh medium with control or NH4+ for 3 d and 6 d of growth, and then NH4+ tissue content was determined. Values are means ±SD of three replicates. (C) GS activities in the shoots of WT and amot1 seedlings. Five-day-old WT and amot1 seedlings were grown on growth medium and transferred to fresh medium with control or NH4+ for 6 d, and then GS activity was determined. Values are means ±SD of three replicates. Different letters indicate statistical differences at P<0.05 (one-way ANOVA with Duncan post-hoc test).
