    Abstract: By a QTL analysis and so forth using 4-HPPD inhibitor-susceptible rice and 4-HPPD inhibitor-resistant rice, a hypothetical gene (HIS1 gene) of an iron/ascorbate-dependent oxidoreductase gene located on a short arm of chromosome 2 of rice has been identified as a 4-HPPD inhibitor-resistance gene. Further, it has also been revealed that a homologous gene (HSL1 gene) of the HIS1 gene is located on chromosome 6 of rice. Furthermore, it has been found out that utilizations of these genes make it possible to efficiently produce a plant having increased resistance or susceptibility to a 4-HPPD inhibitor and to efficiently determine whether a plant has resistance or susceptibility to a 4-HPPD inhibitor.
