摘  要:
以2个番茄溃疡病菌株和其它6种植物病原菌为试验材料,以micA、cytC、TomA等3个特异性基因为检测靶标,采用检测引物设计与优化、特异性测试、灵敏度测试等方法,研究建立番茄溃疡病菌的定性PCR检测方法。结果表明:依据这3个基因建立的PCR检测方法可特异、精准检测番茄溃疡病菌,其中,以TomA基因为检测靶标的方法灵敏度可达到5copy/μL或103 cfu/mL,优于另外2种方法,为番茄溃疡病菌的早期诊断提供了快速、准确的技术手段。

摘  要:
Using two Clavibacter michiganensis subsp.michiganensis strains and six kinds of plant pathogen as experimental materials,through primers design,specificity and sensitivity testing,a PCR method for detection of Clavibacter michiganensis subsp.michiganensis by employing three specific genes of micA,cytC,and TomA were established.The results showed that this developed PCR method resulted in a specific and accurate detection of Clavibacter michiganensis subsp.michiganensis.In particular,the sensitivity of the detection method using TomA gene as test target could reach 5copy/μL or 103 cfu/mL,which was more sensitive than the other two methods by employing micAand cytCgene,respectively.This study provided a fast and precise technological means for the early diagnosis of Clavibacter michiganensis subsp.michiganensis.
