title: What are the principal enzymes oxidizing the xenobiotics in plants: cytochromes P-450 or peroxidases? (A hypothesis).
abstract: Effectively no information is available at present concerning the enzymes which directly participate in the in vivo oxidation of xenobiotics in plants. Based on the known data a hypothesis is presented suggesting that only a minor part of the oxidation of xenobiotics in plants may be catalyzed by cytochrome P-450, the majority of xenobiotics being oxidized by plant peroxidases.
