Root gene expression in response to nitrogen. Relative expression (2-∆CT) of ZmNPF6.6 (a), ZmNRT2.1 (b), ZmNRT2.2 (c), ZmNRT2.5 (d), ZmNRT3.1A (e), ZmAMT1.1A (f), ZmAMT2.1 (g), ZmAMT3.2 (h), ZmAMF1.1 (i) and ZmAMF1.2 (j) in control (C), starved (S) or resupplied (R) roots. Summary of gene expression between starved and resupplied root tissues (k). Gene expression is calculated as relative expression to four control genes (ZmUBQc, ZmSIN3, ZmCullin and ZmElF1). Values are means (±SE) from 3 individual plants. The significance of differences between the values was assessed by one-way ANOVA test
