摘 要: 根据水稻干尖线虫的rDNA-ITS序列,设计出水稻干尖线虫的特异性引物,利用PCR技术对水稻干尖线虫(Aphelenchoides besseyi)部分rDNA-ITS1和部分5.8S基因核苷酸序列进行特异性扩增。实现了单条活的或4%的甲醛(FG)固定的水稻干尖线虫的快速检测。 According to the difference between the sequences of internal transcribed spacer region(ITS) of Aphelenchoides besseyi,A.ritzemabosi and A.fragariae,specific primers were designed for A.besseyi.A single nematode,living or preserved in formalin,could be detected rapidly and A.besseyi was distinguished as well.This method would be useful for rapid detection of nematodes.A polymerase chain reaction(PCR) was used to amplify ribosomal DNA containing partial internal transcribed spacer region 1(ITS1) and partial 5.8S gene.
