PCR and amplification of ITS and 5.8S ribosomal DNA for Fusarium genus detection and identification

Internal transcribed spacer 1 (ITS1),ITS2 and 5.8S rDNA were amplified by PCR and semi-nested PCR to detect Fusarium DNA.Meanwhile, PCR and semi-nested PCR of the region were employed to evaluate the sensitivity and specificity of the method.The amplified DNA was sequenced and blasted against sequences in the GenBank at the National Center for Biotechnology Information.The results proved that this DNA amplifying technique was able to distinguish different species of Fusarium genus.Therefore,amplifying and sequencing of ITS/5.8S rDNA could be a rapid,applicable method for identifying Furisarum genus.
