Abscisic Acid, Stress, and Ripening (TtASR1) Gene as a Functional Marker for Salt Tolerance in Durum Wheat

Figure 3

Expression of TtASR1 in response to abiotic stress and ABA. (a) RT-PCR showing the induction of TtASR1 in leaves of Mahmoudi variety following PEG, salt, and ABA treatments associated with densitometric analysis of the images of RT-PCR products. (b) RT-PCR showing the induction of TtASR1 in leaves of Azizi variety following PEG, salt, and ABA treatments associated with densitometric analysis of the images of RT-PCR products. (c) RT-PCR showing the induction of TtASR1 in roots of Mahmoudi variety following PEG, salt, and ABA treatments associated with densitometric analysis of the images of RT-PCR products. (d) RT-PCR showing the induction of TtASR1 in roots of Azizi variety following PEG, salt, and ABA treatments associated with densitometric analysis of the images of RT-PCR products. Densitometric data are presented as the ratio of pixel intensities for TtASR1 versus actin.
