Expression pattern of 6 NACs in the roots, stems and leaves of Populus simonii×P.nigra under salt stress. The Populus simonii×P.nigra seedlings with new roots and leaves were treated with 150 mM NaCl and water as control, separately. The roots, stems and leaves tissues were harvested at 0, 12, 24 and 36 h with three biological repeats, respectively. Mean values and deviations were calculated from three independent biological experiments
