| چکیده | ||
| To investigate the impact of overexpression of AtNRT2.1 transgene from Arabidopsis on nitrate uptake rate and to understand the regulation of endogenous HATS by nitrate and glutamine amino acid (Gln) in tobacco plants, wild-type and transgenic (F line) plants grown on soil for 4 weeks were transferred to hydroponic culture in a controlled-environment with a 16/8h L:D photoperiod at 24? C/20? C, 70% relative humidity and 150 ? mol. m-2. s-1 light intensity. Nitrate uptake over time was studied by the ion depletion method. Nitrate uptake in the 2 h exposure to 150 ?M nitrate showed an increase in the transgenic line compared to the wild-type plant. Subsequently the uptake trend followed a similar pattern in wild-type plant and transgenic plants | ||
