- Mechanism Induction of peroxidase, polyphenol oxidase and chitinase defense gene products is proposed to explain the reduced powdery mildew incidence on grapevine.
- Intervention effect Pf1-challenged grapevine expressed three peroxidase isoforms, compared with one in the control.
- Intervention effect Pf1 treatment increased the level of PPO induction against powdery mildew in grapevine.
- Observation Four chitinase isoforms were detected in grapevine plants challenged with Pf1.
