摘要: 干旱、高盐、低温、高温等非生物逆境严重影响植物的生长发育,研究参与逆境胁迫应答基因具有重要的理论意义和应用价值。从玉米中克隆了一个CIPK蛋白激酶基因,暂时命名为ZmCIPK10。该基因全长2 730 bp,转录长度2 100 bp,编码438个氨基酸。顺式元件分析发现在基因启动子区域存在ABRE、HSE、TC-rich repeats等推测的逆境顺势元件。荧光实时定量PCR结果表明ZmCIPK10在干旱、低温、盐胁迫下表达量上调,在ABA、高温胁迫下表达量下调。研究结果初步证实ZmCIPK10基因响应非生物逆境胁迫,为ZmCIPK10参与植物逆境信号途径及其功能研究提供理论依据。

Abstract: Drought, high salinity, low temperature and other abiotic stress affect plant growth and development seriously. It has important theoretical and practical value to research key genes involved in stresses. A CIPK protein kinase gene, named ZmCIPK10 tentatively, was cloned in this study. The gene is 2 730 bp long in the genome, 2 100 bp of transcript, encoding 438 amino acids. Cis-element analysis identified ABRE, HSE, TC-rich repeats and other stresses core sequence within the promoter region of the ZmCIPK10 gene. Real-time PCR analysis indicated that the expression of ZmCIPK10 was up-regulated under the dehydration, cold and salt treatment and down-regulated under ABA and heat treatment. This study demonstrated maize ZmCIPKK10 gene took part in stresses responses,which would be helpful to further illustrate the function of ZmCIPK10 in maize.
