Rice ABA signal negative regulatory factor OsUBC12 gene as well as encoding protein and application thereof

The invention discloses a rice ABA signal negative regulatory factor OsUBC12 gene as well as an encoding protein and application thereof, relates to the field of gene engineering, and in particular relates to a rice ABA signal negative regulatory factor gene as well as an encoding protein and application thereof. The invention provides a rice ABA signal negative regulatory factor OsUBC12 gene as well as an encoding protein and application thereof. The nucleotide sequence of the gene is shown as SEQ ID NO: 1 in a sequence table. The amino acid sequence of the encoded protein is shown as SEQ ID NO: 2. Researches show that the osubc12 mutant obtained by a knockout technology shows ABA signal enhanced phenotypes such as delayed seed germination, hypersensitivity of germination and exogenous ABA treatment of seedling growth after germination, related salt tolerance enhancement and the like. The invention is used for negative regulation of rice ABA signals. 水稻ABA信号负调控因子OsUBC12基因及其编码蛋白和应用，涉及基因工程领域，具体涉及一种水稻ABA信号负调控因子
