The present disclosure provides the use of OsHIPP36 gene in the regulation of arsenic tolerance in rice, where protein encoded by the OsHIPP36 gene has the amino acid sequence of SEQ ID NO: 1. The present disclosure obtains a oshipp36 mutant plant by constructing a transgenic vector. After treatment with the external addition of As(III), the mutant plant is found to have significantly increased tolerance to As(III). In particular, the oshipp36 mutant plant after As(III) treatment has significantly longer roots than a Nipponbare wild-type plant, suggesting that the OsHIPP36 gene plays an important role in regulating arsenic tolerance in rice.
