Analysis of DRE binding specificity of SlDREBA4. (A) Construction of the required vectors for the Y1H assay. The bait plasmid pHis2.1 contained three tandem repeat DREs or mDREs and the HIS reporter gene. The coding sequence of SlDREBA4 was cloned into the activation domain GAL4 of the prey plasmid pGADT7. (B) Yeast strain Y187 was co-transformed with bait (pHis2.1-3DRE or pHis2.1-3mDRE) and prey (pGADT7 or pGADT7-SlDREBA4) construct. Interaction between the bait and prey was examined by cell growth on SD medium lacking Trp, Leu, and His (SD-WLH) containing 3-AT.
