Figure 1From: Transcriptome analysis of nitrogen-starvation-responsive genes in rice Induction kinetics of N-starvation-induced genes. Leaf sheaths (a and c) and roots (b and d) of rice seedlings at six-leaf stage were harvested at 3Â h, 6Â h, 12Â h, 1 d, and 2 d after N-starvation and -sufficient treatments were applied. NRT2.3 (a and b) and AMT2.1 (c and d) were used to investigate induction kinetics.Back to article page
