The present invention relates to use of protoporphyrinogen oxidase. A method for controlling weeds comprises applying a herbicide containing an effective dose of PPO inhibitor to a field with at least one transgenic plant. The transgenic plant has a polynucleotide sequence encoding protoporphyrinogen oxidase in a genome thereof, and has reduced plant damage and/or increased plant production compared to other plants that do not have a polynucleotide sequence encoding protoporphyrinogen oxidase. According to the present invention, the protoporphyrinogen oxidase PPOA-PPOF has a relatively high tolerance to a PPO inhibitor herbicide, and the plants having the polynucleotide sequence encoding protoporphyrinogen oxidase have great tolerance to the PPO inhibitor herbicide, and show high-resistance tolerance to almost all 4-fold field concentrations of saflufenacil, oxyfluorfen, and flumioxazin. Therefore, the application prospect for plants is wide.
