| 摘 要： | 为实现对松针中可导致松赤枯病的枯斑拟盘多毛孢的早期检测,依据枯斑拟盘多毛孢ITS区保守序列设计特异性引物AF(R/F),建立了松赤枯病PCR检测体系。结果表明该方法可于枯斑拟盘多毛孢基因组DNA与松针基因组DNA中扩增出大小为480 bp的单一条带,可从无明显症状的组织中检测到枯斑拟盘多毛孢。建立的PCR检测体系适用于枯斑拟盘多毛孢的分子鉴定及松赤枯病的早期诊断。

| Abstract: | In order to realize the early detection of Pestalotiopsis funerea in Pine needles,the specific primer AF(R/F) was designed,and PCR detection system was established according to the conserved sequence of ITS region of P.funerea.The results showed that the method could amplify a single band of 480 bp in genomic DNA of P.funerea and pine needle genomic DNA. P.funerea could be detected in tissues without obvious symptoms.The established PCR detection system was suitable for molecular identification of P.funerea and early diagnosis of pine needle blight. |
