“…The results of the analysis of variance (ANOVA) were in line with the expectations of high morphological variation within populations and low differentiation between populations, as observed in rowans [ 28 , 29 , 31 ] and other insect-pollinated and animal-dispersed tree species [ 45 , 46 , 47 , 48 ]. The relatively high level of among-tree variation within the populations is probably a result of both phenotypic plasticity to specific micro-environmental conditions experienced by each tree, and genetic differentiation among individual trees [ 28 , 29 , 49 ].…”

Service tree, Sorbus domestica L., is a rare and neglected wild fruit tree species of southern and central Europe. Being distributed in different eco-geographical regions, with fragmented and low-density populations, S. domestica represents an interesting model case for investigating patterns of within- and between-population diversity at geographical and environmental scales. This study aimed to analyze the proximate composition, antioxidant activity, and morphometric fruit characteristics. We examined the diversity and population divergences of 49 S. domestica individuals originating from seven populations across continental and Mediterranean eco-geographical regions. In addition, tests of isolation by distance and environment were performed to detect the magnitude of divergence explained by geographic and environmental variables. Significant differences between the studied populations were found in almost all of the studied morphometric and chemical fruit characteristics. The studied service tree populations were characterized by high phenotypic variation despite the low number of trees per population. Model-based population structure analysis using morphometric and chemical fruit characteristics revealed three groups of service tree populations. We concluded that non-effective pollen and seed dispersal along with genetic drift and specific environmental factors resulted in a distinct phenotype with a specific chemical composition in the isolated island population. In addition, a pattern of isolation by the environment was revealed. We infer that morphological and chemical differences between the studied populations in the true service tree from different eco-geographical regions were mediated by adaptation to the specific environmental conditions.

“…As retrotransposon marker systems were successfully used for molecular characterization of Diospyros kaki (Guo et al, 2006), wheat (Carvalho et al, 2010), Citrus (Biswas et al, 2010), grapevine species and cultivars (D'Onofrio et al, 2010;Guo et al, 2014), flax (Smykal et al, 2011), alfalfa (Abdollahi Mandoulakani et al, 2011, cocoyam (Doungous et al, 2015), taro (Doungous et al, 2015), lilium (Lee et al, 2015) and howtron (Rahmani et al, 2015). The aim of the study was to use three iPBS, IRAP and REMAP retrotransposon based marker systems for the first time to analyze the genetic diversity, to compare three different marker systems in order to reveal their diversity indices, to construct phylogenetic trees in order to resolve the relationships in Mediterranean Pistacia species.…”

Retrotransposon movements could lead to major genome rearrangements because of their special transposition mechanism and may be used to analyze differences between species as a marker system. In this context inter primer binding site (iPBS), inter-retrotransposon amplified polymorphism (IRAP) and retrotransposon-microsatellite amplified polymorphism (REMAP) marker systems were used to resolve genetic differences in 7 Mediterranean Pistacia species (P. vera L. cv. Siirt, P. khinjuk Stocks, P. mutica Fischer, P. atlantica Desf., P. palaestina Boiss., P. terebinthus L. and P. lentiscus L.). High level of polymorphism ratio observed in all tested marker systems. Except REMAP, iPBS and IRAP marker systems showed strong mantel correlations. Phylogenetic tree with neighbor joining (NJ) method depicted that Mediterranean Pistacia species may be divided into three clades: (i) P. vera -P. khinjuk, (ii) P. mutica -P. atlantica and (iii) P. palaestina -P. terebinthus with P. lentiscus. Principal component analysis (PCA) plots showed 4 distinct clusters. In conclusion, retrotransposon based marker systems could be useful for analyzing molecular diversity in Pistacia genus due to their highly polymorphic nature and ease of use.

“…Zhang et al (2008), Khiari et al (2015) and Emami et al (2018) also used SSRs developed from apple and pear. Few studies in the literature have evaluated the molecular characterization of hawthorn genotypes (Zhang et al 2008;Dai et al 2009;Rajeb et al 2010;Yilmaz et al 2010;Beigmohamadi and Rahmani 2011;MirAli et al 2011;Serce et al 2011;Khiari et al 2015;Rahmani et al 2015;Erfani-Moghadam et al 2016;Fang et al 2017;Emami et al 2018). In the current study, we present polymorphic SSR loci for hawthorn that were developed from apple and pear (Table 3).…”

Hawthorn (Crataegus spp.) is an edible wild fruit that is used in traditional medicine, landscape studies, and food and beverage industries in many countries. It is an important wild plant species in Turkey and is numerous in the Yozgat Province. Genetic and breeding studies on hawthorn are very limited. Therefore, we aimed to characterize 91 hawthorn genotypes using simple sequence repeat (SSR) markers. The SSRs were developed from apple and pear and were screened in hawthorn for amplification and polymorphisms. A total of 265 alleles were detected from thirty-two SSR primer pairs, and those were used to identify genetic relationships. The number of alleles ranged from 2 to 21 alleles per locus with a mean value of 8.28. The Hi05b09 locus showed the highest allele number (Na = 21). The polymorphism information content (PIC) values ranged from 0.16 (CH03d10) to 0.89 (C6554) with a mean value of 0.60. An Unweighted Pair Group Method with Arithmetic Average method was used to cluster the genotypes, and four major clusters were obtained from the amplification of the SSRs. STRUC-TURE software identified four populations (DK = 4) and eight sub-populations (DK = 8), and four major clusters similar results to UPGMA analysis. Our study showed that the SSR markers could be utilized as a reliable tool for the determination of genetic variations and relationships of hawthorn genotypes. A basic molecular analysis on the hawthorn genotypes identified in this study will promote the collection of germplasm collection and the selection of parents' in future cross-breeding studies.
