OsJAB1 protein and application thereof in improving salt stress tolerance of rice

The invention discloses an OsJAB1 protein and application thereof in improving salt stress tolerance of rice. The amino acid sequence is shown as a sequence table SEQ ID NO: 1, and the nucleotide sequence is shown as a sequence table SEQ ID NO: 2. The OsJAB1 protein improves the oxidation resistance of a plant photosynthetic system and improves the salt stress tolerance of plants by regulating the stability of a key enzyme synthesized by a plant antioxidant vitamin C. Research results show that the OsJAB1 protein plays an important role in improving the salt stress tolerance of plants. The invention has important application value for cultivating high-salt-stress-tolerance plants and high-yield crop varieties. 本发明公开了OsJAB1蛋白及其在提高水稻盐胁迫耐性中的应用。其氨基酸序列如序列表SEQ ID NO：1所示，核苷酸序列如序列表SEQ ID NO：2所示。OsJAB1蛋白通过调控植物抗氧化物维生素C合成关键酶稳定性，提高植物光合系统抗氧化能力，提高植物盐胁迫耐性。研究结果表明OsJAB1蛋白在提高植物盐胁迫耐性中具有重要作用。本发明对于培育高盐胁迫耐性植物和高产作物品种具有重大的应用价值。
