Figure 2.
The relative expression of N metabolism-related genes varied depending on accessions and N conditions. Relative expression of GLU1 (A) and GLN1.1 (B) illustrating the differential responses to starvation among accessions (means ± SE). Stars indicate the significance of the difference between the means of the control and of the N starvation condition for each accession: ns non-significant, * p < 0.05, ** p < 0.01, *** p < 0.001, n = 8. Dark and light greys show the plant in the control and N starvation conditions, respectively.
