To provide a protoporphyrinogen oxidase (PPO) variant that imparts resistance to herbicides to crops to be cultivated so as not to affect the growth of the crops to be cultivated while using herbicides, and provide a technology of conferring and/or enhancing herbicide tolerance of plants or algae using the variant.SOLUTION: A PPO variant comprises a specific amino acid sequence. The sequence corresponds to a gene for the hemY type porphyrin synthetic pathway isolated from a prokaryote, which synthesizes chlorophyll and heme important in the metabolic process of plants.SELECTED DRAWING: None 【課題】除草剤を使用しながらも栽培対象作物の生長には影響を与えないようにするための、栽培対象作物に除草剤に対する耐性を付与する、プロトポルフィリノーゲンオキシダーゼ（ＰＰＯ）の変異体、およびこれを用いて植物および／または藻類の除草剤に対する耐性を付与および／または増進させる技術を提供する。【解決手段】植物の代謝過程で重要な葉緑素とヘムを合成する、原核生物から分離されたｈｅｍＹタイプのポルフィリン合成経路の遺伝子である、特定のアミノ酸配列を有すＰＰＯ変異体による。【選択図】なし
