Interpretive Summary:

Technical Abstract: The metabolism of pesticides by plants is a key factor in the susceptibility and tolerance of a species to a given pesticide, whereas metabolism by prokaryotes is often a key determinant in the environmental fate of that pesticide. Thus, understanding pesticide metabolism in both groups of organisms is crucial for efficient and environmentally sound pesticide management. The pathways of pesticide detoxification in plants have been traditionally divided into several metabolic phases, wheras bacterial biotransformations are characterized as either metabolic or co-metabolic. There are common transformation mechanisms of many pesticides in both plants and bacteria; however, some prokaryotes are unique because they can completely metabolize certain pesticides to mineral components (mineralization). The diversity of biotransformations in prokaryotic organisms for a given pesticide is also generally greater than in plants.
