摘要: 筛选到应用于多主棒孢实时荧光定量PCR检测的特异性引物CIR5/CIF5,并建立了土壤中多主棒孢的实时荧光定量PCR检测技术。引物CIR5/CIF5能够从多主棒孢基因组DNA中特异性扩增出一条259 bp的片段,常规PCR检测中灵敏度可达10 fg/μL。利用实时荧光定量PCR检测模拟带菌土壤中的带菌量,结果证明该技术对土壤中多主棒孢的检测下限为1个孢子/g土壤,可以快速、准确地定量土壤中病原菌的孢子数目,为栽培前土壤中病原菌的监测预报提供有效的技术手段。

关键词: 多主棒孢, 实时荧光定量PCR, 土壤检测

Abstract: In this research, a specific primer pair CIR5 /CIF5 for C. cassiicola was developed, and Real-time PCR based specific detection method of this pathogen in soil was established. The primer pair gave a single amplifi- cation of 259 bp from C. cassiicola and could be distinguished from other soil-borne pathogen strains. The detection limit was 10 fg/μL in conventional PCR. The pathogen in soil could be detected by Real-time quantitative PCR, and the sensitivity was down to C. cassiicola DNA of 1 conidia/g. This Real-time quantitative PCR method could assist in the implementation of quarantine measures for prevention and control of Corynespora spot leaf.

Key words: Corynespora cassiicola, Real-time quantitative PCR, Soil detection
