SUMMARY Evidence is presented which suggests that cytochrome P‐450, in plants, probably functions as in all other eukaryotic organisms, principally as a detoxification mechanism. In plants this function is largely suppressed during tissue maturation coinciding with cell vacuolation. The consequential accumulation and isolation of potential toxins within vacuoles provides higher plants with an anti‐herbivore defence of evolutionary significance.
