Transformation of potato with cucumber peroxidase: Expression and disease response
Peroxidase is thought to be important in a variety of plant defence responses against pathogens. Potato was transformed with a cucumber anionic peroxidase under the control of the cauliflower mosaic virus 35S promoter, which is highly expressed in potato tuber tissue. This particular peroxidase is associated with the induced resistance response in cucumber. High levels of transgenic peroxidase activity were expressed in tuber tissue. However, the increase in peroxidase activity had no effect on disease caused byFusarium sambucinum, Erwinia carotovora, orPhytophthora infestans.Levels of soluble phenolics and polyphenol oxidase in the transgenic tubers were unaffected, while the amount of lignin declined slightly.
