Relative expression level of 170 non-redundant NACs in the leaves of Populus simonii×P.nigra with salt treatment. The Populus simonii×P.nigra seedlings with new roots and leaves were treated with 150 mM NaCl and water as control, separately. The leaves were harvested at 24 h with three biological repeats. Mean values and deviations were calculated from three independent biological experiments
