Wild pistachio species is important species in forests regions Iran and provide protection wind and soil erosion. Even though cultivation and utilization of Pistacia are fully exploited, the evolutionary history of the Pistacia genus and the relationships among the species and accessions is still not well understood. Two molecular marker strategies, SCoT and IRAP markers were analyzed for assessment of 50 accessions of this species accumulated from diverse geographical areas of Iran. A thorough of 115 bands were amplified using eight IRAP primers, of which 104 (90.4 %) have been polymorphic, and 246 polymorphic bands (68.7 %) had been located in 358 bands amplified by way of forty-four SCoT primers. Average PIC for IRAP and SCoT markers became 0.32 and 0.48, respectively. This is exposed that SCoT markers have been extra informative than IRAP for the assessment of variety among pistachio accessions. Primarily based on the two extraordinary molecular markers, cluster evaluation revealed that the 50 accessions taken for the evaluation may be divided into three distinct clusters. Those results recommend that the performance of SCoT and IRAP markers was highly the equal in fingerprinting of accessions. The results affirmed a low genetic differentiation among populations, indicating the opportunity of gene drift most of the studied populations. These findings might render striking information in breeding management strategies for genetic conservation and cultivar improvement.
野生阿月浑子物种是伊朗森林地区的重要物种,具有防风和防止土壤侵蚀的作用。尽管阿月浑子属的栽培和利用已得到充分开发,但该属的进化历史以及物种和种质之间的关系仍未得到很好的理解。为了评估从伊朗不同地理区域收集的50份该物种种质,分析了两种分子标记策略,即目标起始密码子多态性(SCoT)和反转录转座子插入多态性(IRAP)标记。使用8条IRAP引物扩增出115条带,其中104条(90.4%)具有多态性,通过44条SCoT引物扩增出358条带,其中246条多态性带(68.7%)。IRAP和SCoT标记的平均多态信息含量(PIC)分别为0.32和0.48。这表明在评估阿月浑子种质间的多样性方面,SCoT标记比IRAP标记提供了更多信息。基于这两种不同的分子标记进行聚类分析,结果显示用于评估的50份种质可分为三个不同的类群。这些结果表明,SCoT和IRAP标记在种质指纹图谱分析中的表现高度一致。结果证实了种群间遗传分化较低,这表明在所研究的种群中存在基因漂变的可能性。这些发现可能为遗传保护和品种改良的育种管理策略提供显著信息。
