Genetic diversity and relationships among Hypericum L. species by ISSR Markers: A high value medicinal plant from Northern of Iran

Hypericum L. species are generally known locally in Iran with the names “Hofariqun” which Ebn Sina (or Bo Ali Sina) called it. Plants of genus have traditionally been used as medicinal plants various parts world. perforatum is source to one most manufactured and herbal preparations recent years, especially a mild antidepressant. Therefore, due importance these plant species, we performed molecular data for this species. For study, 175 randomly collected from 17 9 provinces. Amplification genomic DNA using 10 primers produced 141 bands, 127 were polymorphic (95.78%). The obtained high average PIC MI values revealed capacity ISSR detect loci among genetic similarities collections estimated 0.617 0.911. According Inter-Simple sequence repeats (ISSR) markers analysis, H. androsaemum hirtellum had lowest similarity perforaturm triquetrifolium highest similarity. aims present study are: 1) can identify 2) what structure taxa Iran, 3) investigate inter-relationship? that
