Figure 2From: Roles of ArabidopsisWRKY3 and WRKY4 Transcription Factors in Plant Responses to PathogensDNA binding activity of WRKY3 and WRKY4. A. Sequences of oligonucleotide probes. The Pchn0 probe contains two TTGACC W boxes, while in the mPchn0 probe, the TTGACC sequences are mutated to TTGAAC. The wild-type and mutated W-box sequences are underlined. B. Electrophoretic mobility shift assay (EMSA) of DNA binding of the WRKY3 and WRKY4 recombinant proteins.Back to article page
