NtAQP1 impact on Arabidopsis plant dry weight under normal and 100 mm NaCl irrigation. A, Arabidopsis plants (45 d old) constitutively expressing NtAQP1 (top row) and control plants (bottom row) grown in a controlled growth room under normal irrigation regime (left) and 100 mm NaCl irrigation regime (right) for 33 d. B, Mean ± se shoot dry weight of Arabidopsis plants overexpressing NtAQP1 and control plants under normal (n_NtAQP1 = 11, n_control = 8) and 100 mm NaCl (n_NtAQP1 = 12; n_control = 6) irrigation conditions. Different letters indicate significant differences (t test, P < 0.05). [See online article for color version of this figure.]
