| 摘要 |
Internal Transcribed Spacer (ITS) DNA sequences from the ribosomal RNA gene region are described for different species and strains of Helminthosporium carbonum, Helminthosporium turcicum, Helminthosporium maydis, Cercospora zeae-maydis, Kabatiella zeae and Puccinia sorghi. Specific primers from within these sequences are identified as being useful for the identification of the fungal isolates using PCR-based techniques. |
