The SsDREB Transcription Factor from the Succulent Halophyte Suaeda salsa Enhances Abiotic Stress Tolerance in Transgenic Tobacco

Figure 3

Quantitative real-time PT-PCR analysis of SsDREB. (a) Transcript levels of SsDREB in the roots, stems, and leaves of untreated plants. (b), (c) The relative expression level of SsDREB in S. salsa leaves at indicated time points exposed to salinity stress (250 mM NaCl), dehydration stress (20% PEG), low temperature (4°C), and 100 μM ABA, respectively. Columns indicate relative expression levels of SsDREB normalized against levels of SsActin as calculated by real-time qRT-PCR (mean ± SE of three biological replicates).
