چکیده مقاله:
Background: Start Codon Targeted (SCoT) and Inter-Simple Sequence Repeat (ISSR) markers were used to appraisegenetic diversity existed in ۲۰ samples of four Iranian pistachio (Pistacia vera L.) cultivars and relative efficiencies of themarker systems were compared.Materials and Methods: ۲۰ and ۱۵ primers were used in SCoT and ISSR markers, respectively. Effective Multiplex Ratio(EMR), Marker Index (MI), Resolving Power (RP) and Polymorphic Information Content (PIC) of the primers were assessedfor the two marker systems. Cluster analysis for molecular data was performed. Principal Coordinate Analysis (PCoA) wasdone too.Results: The most of the parameters examined were found to be more suitable in ISSR system. The most remarkable resultof the current research is that cluster analysis on SCoT and ISSR data clearly discriminated the cultivars in terms of theirgenetic characterizations. There was a high similarity between dendrogram derived from ISSR marker and dendrogramderived from both markers, in spite of some observed differences.Conclusions: It is shown in the current research that there is remarkable genetic diversity among evaluated samples. SCoTand ISSR analysis produces adequate polymorphisms for DNA fingerprinting. This research reports the first application of theSCoT marker in characterization of Iranian pistachio cultivars.
