Transcription factor OsNAC15 gene for regulating and controlling drought and salt stress tolerance of rice and application of transcription factor OsNAC15 gene

The invention belongs to the technical field of plant genetic engineering, and particularly relates to a transcription factor OsNAC15 gene for regulating and controlling drought and salt stress tolerance of rice and application. The invention provides an NAC transcription factor gene OsNAC15, the nucleotide sequence of the NAC transcription factor gene OsNAC15 is shown as SEQ ID NO: 1, and the sequence of protein coded by the gene is shown as SEQ ID NO: 2. The gene plays a role in participating in drought and salt stress tolerance of rice. The tolerance of the rice to drought and salt stress is regulated and controlled by over-expression in a rice plant, so that the gene can be applied to cultivation of drought-resistant and salt-resistant rice strains, and can be used as a marker gene of the drought-resistant and salt-resistant rice. 本发明属于植物基因工程技术领域，具体涉及调控水稻对干旱和盐胁迫耐受性的转录因子OsNAC15基因及应用。本发明提供了一个NAC转录因子基因OsNAC15，其核苷酸序列如SEQ IDNO：1所示，该基因编码的蛋白质的序列如SEQ ID NO：2所示。所述基因在参与水稻对干旱和盐胁迫耐受性中发挥作用。通过在水稻植株中超量表达实现调控水稻对干旱和盐胁迫的耐受
