Abstrakt

Transformation of various xenobiotics by plant cells usually proceeds in three phases: derivatization of the xenobiotic to a more polar and reactive agent (phase 1), conjugation (phase 2) and secondary conjugation (phase 3) with endogenous molecules. The mixed-function oxidases with cytochromes P450 as terminal oxidases and peroxidases rank among the enzymes of phase 1. These enzymes, in addition to other functions, probably play an important role in the metabolism of xenobiotics in plants. The mechanisms of detoxification are described.
