NIGT1.2 Reduces Arabidopsis Nitrate Influx under Low-Pi Stress.

(A) N concentration of 7-d-old NIGT1.2-overexpressing lines transferred to MS medium for another 7 d. Data are shown as mean ± se (n = 3).

(B) N concentration of 7-d-old nigt1.2-1, nigt1.1, and nigt1.1 nigt1.2 double mutants transferred to MS or LP medium for 7 d. Data are shown as mean ± se (n = 3).

(C) 15NO3− influx of 7-d-old NIGT1.2-overexpressing lines and wild-type plants transferred to MS medium for another 7 d. Data are shown as mean ± se (n = 4).

(D) 15NO3− influx of 7-d-old nigt1.2-1, nigt1.1, nigt1.1 nigt1.2 double mutant and wild-type plants transferred to MS or LP medium for 7 d. Data are shown as mean ± se (n = 3). Asterisks in (A), (B), (C), and (D) indicate significant differences compared with wild-type plants (#) by Student’s t test: *P < 0.05; **P < 0.01.
