Potentiation of developmentally regulated plant defense response by AtWRKY18, a pathogen-induced Arabidopsis transcription factor.

AtWRKY18 is a pathogen- and salicylic acid-induced Arabidopsis transcription factor containing the plant-specific WRKY zinc finger DNA-binding motif. In the present study, we have transformed Arabidopsis plants with AtWRKY18 under control of the cauliflower mosaic virus 35S promoter. Surprisingly, transgenic plants expressing high levels of AtWRKY18 were… (More)
