Fig. 3. Constitutive expression of presumptive drought- or salinity–responsive genes. Primer pairs used for RT-PCR are listed in Table 1. The cDNAs were synthesized from total RNAs isolated from leaves of control plants (CL) or 6-d drought-treated plants (DL), or from control seedling roots (CR) and shoots (CS), or from 6-h salt-treated seedling roots (SR) and shoots (SS). The 18S rRNA was used as an internal control for amplification.
