摘要: Roots of Helianthemum species were collected from various rangeland sites in Fars, and other provinces Iran. The partial small subunits ribosomal DNA genes amplified with the genomic extracted their roots by nested polymerase chain reaction (PCR) using universal fungal primer pair ITS1/ITS4 specific FTC/RTC, which was designed based on internal transcribed spacer 1, 2 5.8S gene rDNA sequences Terfezia claveryi. nested-PCR sensitive enough to re-amplify direct-PCR product, resulting a fragment 500 bp. efficacy showed that it could product detect 2fg DNA. Restriction length polymorphism (RFLP) analyzed two restriction enzymes Hinf I Alu I. Nucleotides sequence analysis revealed infected close those T. claveryi . With PCR method, H. lipii salicifolium confirmed as host plants greenhouse inoculated also rangelands different areas Fars
