Pistachio (Pistacia vera L.) is one of the most significant hard-shelled nuts. Pistachio has heterozygous genomic nature due to its allogamy plant species. There are several problems in Pistacia breeding programs and different biotechnological approaches prefer to overcome these limiting factors. The aims of present study were the development of the novel genic microsatellites (eSSRs) derived from P. vera, the identification of the transferability of eSSRs, and the determination of the polymorphism level of the genomic (gSSR) and eSSRs in major pistachio cultivars. A total of 154 eSSR were developed and the transferability of 223 eSSRs across the genus Pistacia was detected. Average transferability rate was calculated as 84.9% in seven Pistacia species. The highest number of loci (200) was amplified in P. terebinthus, whereas 107 loci were amplified in seventeen species. A total of 143 set of polymorphic SSR primer pairs (74 genomic and 69 genic SSRs) were utilized for the comparison of polymorphism levels of gSSRs and eSSRs markers in major pistachio cultivars. Of the 74 gSSR and 69 eSSR markers, 70 and 39 SSR markers showed scorable polymorphic loci, respectively. gSSRs produced higher polymorphism than eSSRs in major pistachio cultivars. These differences may be due to the genomic structure of the markers, as well as the design of eSSRs from more conserved regions, or the development of gSSRs from intron and intergenic regions found throughout the entire genome. The detection of polymorphic SSRs can be used for Pistacia cultivars or genotype identifications, DNA fingerprinting in the nursery and in future breeding programs. [ABSTRACT FROM AUTHOR]
