诱导型黑芥子酶协助蛋白(iMyAP)往往与黑芥子酶和黑芥子酶结合蛋白一起以复合体的形式存在,对植物的防御系统有着重要的作用。为了研究黑芥子酶协助蛋白在植物响应非生物胁迫方面的功能,通过以pBI121为载体,分别构建了CaMV35S::iMyAP9和CaMV35S::iMyAP 12,浸花法转化拟南芥,用卡那霉素对转化植株进行筛选,并对抗性苗进行PCR检测,初步得到67株转基因植株;提取转基因拟南芥中RNA进行RT-PCR表达分析。结果表明,iMyAP9基因和iMyAP12基因在随机挑选的转基因拟南芥中获得了有效的表达。拟南芥转基因植株的获得为进一步探讨iMyAP9基因、iMyAP佗基因的生物学功能奠定了基础。
The Over-expression Vector Construction of BnaiMyAP9 and BnaiMyAP12and Transformation of Arabidopsis thaliana
Inducible Myrosinase-associated protein (iMyAP) usually occur in complexes with Myrosinases and Myrosinases-binding protein plays important roles in the plant' s defense system. To study the functions of iMyAP in abiotic stress responses, we constructed two plant over-expression vectors CaMV35S::iMyAP9 and CaMV35S::iMyAP12. Genetic transformation of Arabidopsis was performed by floral dip method. The T0 seeds were screened on medium with kanamycin and the anti-kanamycin plants were tested by PCR to confirm if anti-Kan plants were transgenic plants. 67 transgenic plants were obtained. The results of RT-PCR showed that iMyAP9 and iMyAP12 genes efficiently expressed in the transgenic arabidopsis plants, which the results lay a foundation for further studying the biological function of iMyAP9 and iMyAP12 genes.
