  • Two new WRKY transcription factors from parsley (Petroselinum crispum), WRKY4 and WRKY5, were isolated using the yeast one-hybrid system. In yeast, both proteins interacted sequence-specifically with W boxes (TTGACC) and activated transcription. They appear to contain functional leucine zippers, which increase their affinities for W boxes. Co-transfection experiments in parsley protoplasts confirmed their in vivo-binding specificity for W boxes. Elicitor-mediated expression of the WRKY5 gene… CONTINUE READING
