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

Figure 1

Conserved domain and phylogenetic analysis of SsDREB protein. (a) SsDREB protein has the same AP2 domain compared with other DREB proteins from Arabidopsis thaliana, Zea mays, Gossypium hirsutum, Setaria italica, and Oryza sativa. The 14th valine and the 19th leucine acid inside the AP2/ERF domain are presented in boxes. (b) Phylogenetic analysis of proteins from DREB subfamily. The number was the bootstrap value of the clade and low bootstrap values (<50) were removed from the tree. The accession number of each appended protein is as follows: AtCBF1 (AAC49662), AtCRT/DREB2 (AAD15976), AtCRT/DREB3 (AAD15977), NtDREB1A (ABD65969), CbCBF (AAR26658), BnCBF-like (AAL38242), BnCBF16 (AAM18960), GhDREB1-like (ABD65473), SlCBF3 (AAS77819), SlCBF2 (AAS77821), PaDREB1 (BAD27123), CaCBF1B (AAQ88400), OsDREB 1B (AAN02488), OsDREB 1A (AAN02486), ZmDREB2 (AAM80485), ZmDREB-like (AAN76804), AtRAP2.1 (AAC49767), AtRAP2.4 (AAC49770), SlCBF1 (AAK57551), AtTINY (CAA64359), AtDREB2B (BAA33795), AtDREB2A (BAA36705), ZmDREB1 (AAM80486), AtAP2 (AAC39489), ZmERF/AP2 (BAE96012), GmDREB (AAP83131), EsDREB2A (AAS58438), OsDBF1 (AAP56252), GhDREB1 (AAO43165.1), CbCBF25 (AAR35030), GmDREBa (AAT12423), BdABI4-like (XP_003568646), SiABI4-like (XP_004963859), BrDREB2A-like (XP_009125600), BpDREB (ABB89755.1), GmDREB (ABB36645), OsDREB1F (AAX23723), and GhDREB2 (AAT39542).
