Promoter cloning and analysis of TaWRKY2. (A) The 2,166-bp promoter upstream of the ATG start codon of TaWRKY2. (B) Analysis of the cis-regulatory promoter elements. (C) Responsiveness of the promoter to the following abiotic stresses: (a) control, (b) drought (20% polyethylene glycol for 24 h), (c) salt (300 mM NaCl for 24 h), (d) heat (37°C for 12 h), (e) cold (4°C for 12 h), (f) sprayed with H2O for 24 h, and (g) sprayed with ABA (200 mM for 24 h).
