PROBLEM TO BE SOLVED: To impart resistance to a herbicide to a crop to be cultivated so as not to affect the growth of the crop to be cultivated while using a herbicide, a variant of protoporphyrinogen oxidase (PPO). , And using it to impart and / or enhance resistance to herbicides in plants and / or algae. SOLUTION: A PPO mutant having a specific amino acid sequence, which is a gene of a hemeY type porphyrin synthesis pathway isolated from a prokaryote, which synthesizes chlorophyll and heme important in the metabolic process of a plant.
