通过PCR方法从水稻cDNA中克隆得到转录因子Os1137的编码基因,构建由ubi启动子驱动的该基因的植物表达载体p3300-Os1137,并用农杆菌介导法将其导入烟草,研究不同盐浓度下转基因烟草的生理指标,分析其抗盐性。结果表明,将该基因导入烟草植株中能够显著抑制NaCl胁迫下植物体内MDA含量的增加,并能够提高植物体内的脯氨酸含量。该基因能够提高转基因烟草植株的抗盐性。 The coding gene of transcription factor Os1137 was cloned from rice by PCR, and the plant expression vector p3300-Os1137 driven by ubi promoter was constructed. The gene was introduced into tobacco by Agrobacterium tumefaciens method and the transgene Tobacco physiological indicators, analysis of its salt resistance. The results showed that the introduction of this gene into tobacco plants could significantly inhibit the increase of MDA content in plants under NaCl stress and increase the content of proline in plants. This gene can improve the salt resistance of transgenic tobacco plants.
