摘要:
针对引起玉米穗腐病的禾谷镰刀菌(Fusarium graminearum),根据翻译延伸因子基因(EF1alpha)的保守区域设计特异性引物,通过优化反应时间和温度,建立一种灵敏、快速的环介导等温扩增(LAMP)检测方法,并对优化的F. graminearum LAMP反应体系进行特异性、灵敏度及可行性检测。结果表明,该LAMP方法能够有效检测禾谷镰刀菌的基因组DNA,64 ℃、45 min为最优反应条件。在最佳条件下,该方法对禾谷镰刀菌具有良好的特异性,检测灵敏度可达到100 pg/μl。该检测方法为禾谷镰刀菌引起的玉米穗腐病的田间快速诊断及病原菌监测奠定了基础。
Abstract:
To detect the effect of Fusarium graminearum on ear rot of maize, the loopmediated isothermal amplification (LAMP)specific primers were designed based on EF1alpha, and the reaction time and temperature were optimized. The specificity, sensitivity and feasibility of the optimized Fusarium graminearum LAMP reaction system were tested. The results showed that the genomic DNA of Fusarium graminearum could be detected effectively by established LAMP method with the optimum reaction conditions of 64 ℃, 45 min. Under the optimal conditions, the LAMP method had good specificity, and the detection sensitivity could reach 100 pg/μl. Development of the method lay a foundation for the rapid diagnosis and pathogen monitoring of ear rot of maize caused by Fusarium graminearum in the field.
