A study of the genetic relationships among Petrorhagia taxa from Turkey was carried out using inter-simple sequence repeat (ISSR) markers. A total of 409 amplified bands were obtained by 10 ISSR primers. The polymorphism ratio was high (100%) across 45 individuals representing nine Petrorhagia taxa (P. dubia, P. prolifera, P. pamphylica, P. peroninii, P. saxifraga, P. cretica, P. alpina subsp. alpina, P. alpina subsp. olympica, P. lycica) and was sufficient to distinguish each species. Statistical analyses were performed by using POPGENE, GenAlEx6, and PAUP. An unweighted pair-group method with arithmetic mean (UPGMA) dendrogram was constructed based on Nei’s genetic distance along with outgroup species (Velezia rigida) in MEGA4. The dendrogram shows two main clusters, the first one (Cluster-I) included only P. lycica, while the cluster-II contained all other taxa. Cluster-II can be grouped in two sub-clusters, with P. prolifera and P. saxifraga constituting a first sub-cluster, the other species (P. alpina subsp. alpina, P. alpina subsp. olympica, P. cretica, P. dubia, P. peroninii and P. pamphylica) being grouped in a second sub-cluster. Both PCoA and Neighbour-Net network analysis supported the dendrogram. The study showed that ISSR technique can be successfully used in species identification and determination of the genetic relationships between Petrorhagia species distributed in Turkey.

The genetic diversity of 27 mulberry (Morus spp.) genotypes mainly from China was investigated using inter-simple sequence repeat (ISSR) markers to assist in addressing breeding objectives and conserving existing genetic resources. Of the 22 primers screened, 15 produced highly reproducible ISSR bands. Using these 15 primers, 138 discernible DNA fragments were generated with 126 (91.3%) being polymorphic, indicating considerable genetic variation among the mulberry genotypes studied. Genetic similarity ranged from 0.6014 between Yu 2 and Yu 711 to 0.9493 between Cuizhisang and Dejiang 10. The phenetic dendrogram based on ISSR data generated by the unweighed pair group method with arithmetical averages (UPGMA) method grouped the 27 accessions into two major clusters: cluster I, cultivated mulberry species (M. multicaulis Perr., M. alba Linn., M. atropurpurea oxb., M. bombycis Kiodz., M. australis Poir., M. rotundiloba Kiodz., M. alba var. pendula Dipp., M. alba var. macrophylla Loud., and M. alba var. venose Delile.); and cluster II, wild mulberry species (M. cathayana Hemsl., M. laevigata Wall., M. wittiorum Hand-Mazz., M. nigra Linn., and M. mongolica Schneid.). Our molecular analyses agree with the existing morphological classification of Morus and clarify the genetic relationships among mulberry species.

A collection of 18 accessions of sour orange (Citrus aurantium L.) coming from Sicily and other countries was investigated by two polymerase chain reaction (PCR)-based DNA marker technologies. Ten inter-simple sequence repeat (ISSR) primers and fifteen randomly amplified polymorphic DNA (RAPD) primers were used to identify and to evaluate the genetic variability and relationship of accessions. A total of 111 ISSR and 145 RAPD amplified fragments were used to estimate the Dice's coefficient of similarity for cluster analysis using a unweighted pair-group method using an arithmetic averaging (UPGMA) algorithm. The genetic relationships identified using ISSR and RAPD markers were highly concordant, such that the correlation between ISSR and RAPD genetic distance (GD) estimates was r = 0.93. The ISSR and RAPD analysis of 18 sour orange accessions found a high grade of genetic diversity in foreign accessions, while a low variability was detected in local accessions. Sicilian accessions could be grouped in two distinct clusters, including indistinctly plants from three origin regions. Some markers could be linked to the different growing areas. The ISSR and RAPD molecular reference system seems to be suitable for a fine identification of tightly related plants and the obtained results can form the basis for future setting up of Citrus rootstock genetic improvement projects.

AbstractThe Inter-Simple Sequence Repeat (ISSR) was used in this study for genetic fingerprinting and identification of 28 important Populus L. (poplar) cultivars (varieties/ clones), and determination of the genetic relationships among these cultivars. These 28 cultivars belonged to sections Aigeiros, Tacahamaca, Leuce, Turanga, and hybrids between sections Aigeiros and Tacahamaca. Out of 27 ISSR primers tested, eight primers generated clear multiplex profiles. The best three primers produced 154 easily detectable fragments, 129 (84%) of which were polymorphic among the cultivars. Each of these 3 primers produced fingerprint profiles unique to each of the accessions studied, and thus could be solely used for their identification. Twenty-five markers, unique to 10 of the cultivars studied, were detected. These markers may be converted into cultivar-specific probes for identification purposes. Genetic relationships among the cultivars were evaluated by generating a similarity matrix based on the simple matching coefficient and the unweighted pair group method with arithmetic average (UPGMA) dendrogram. The results showed a clear-cut separation of cultivars among different sections of poplar, and were in agreement with the genealogy of the sampled cultivars. The present study shows that ISSR markers could generate abundant polymorphism, are reproducible, and are quick for characterization of poplar cultivars. In the future, the markers used in this study, in combination with other molecular techniques, could provide a useful panel of ISSR markers for largescale DNA fingerprinting of poplar cultivars and determination of the genetic relationships among these cultivars.

The goal of this study was to determine the level of genetic diversity and relatedness among 16 strawberry (Fragaria H ananassa Duch.) cultivars and 11 breeding lines developed in Canada, using Inter Simple Sequence Repeat (ISSR) markers. Seventeen primers generated 225 polymorphic ISSR-PCR bands. Cluster analysis by the unweighted pair-group method with arithmetic averages (UPGMA) revealed a substantial degree of genetic similarity among the genotypes ranging from 63 to 77% that were in agreement with the principal coordinate (PCO) analysis. Geographical distribution for the place of breeding program explained only 1.4% of total variation as revealed by analysis of molecular variance (AMOVA). The ISSR markers detected a sufficient degree of polymorphism to differentiate among strawberry genotypes, making this technology valuable for cultivar identification and for the more efficient choice of parents in current strawberry breeding programs.

AbstractBroomrapes (Orobanche L.) are holoparasitic plants, parasitizing roots of a wide range of host plants. In this study, genetic polymorphism among 44 Orobanche aegyptiaca Pers. individuals collected from different regions of northwest Iran was investigated using inter-simple sequence repeat (ISSR) markers. Two hundred-sixty one discernible bands were amplified using 20 ISSR primers which 245 (94%) was polymorphic, indicating considerable genetic variation among the examined individuals. The number of polymorphic bands per primer ranged from 4 to 17, averaging 12.25. UPGMA clustering using Jaccard’s similarity coefficients revealed six main groups. Genetic similarity coefficients varied from 0.71 (between individuals 23 and 27) to 0.34 (between 13 and 30). A model-based Bayesian approach subdivided 38 out of 44 broomrape genotypes into 2 genetic groups and the remaining ones were categorized as mixed genotypes based on Q values. According to an analysis of molecular variance, 99% of the total variation was partitioned within genetic groups. The results demonstrated the potential usefulness of ISSR markers for determination of genetic variation in O. aegyptiaca. Understanding the variability in broomrape is important when attempting to develop resistant host crops against this parasite.

More recently the use of different molecular markers in fruit species to determine particularly genetic diversity, genetic relationships and cultivar identification has been gained more importance. In the study, 13 randomly amplified polimorfic DNA (RAPD) and 4 inter-simple sequence repeat (ISSR) markers were used to evaluate genetic relationships among 95 almong accessions (26 foreign cultivars and 69 national cultivars and selections). The all plant material found in Almond Germplasm Repository in Gaziantep, Turkey. Both RAPD and ISSR markers distinguished the almond cultivars and selections in various levels. 17 RAPD and ISSR markers yielded a total of 73 scorable bands, which 51 are polymorphic. The two marker system exhibited variation with regard to average band sizes and polymorphism ratio. The average polymorphism was higher in ISSR (88%) compared to RAPD (74%). RAPD and ISSR marker systems were found to be useful for determining genetic diversity among almong genotypes and cultivars. Combining of two dendrograms obtained through these markers show different clustering of 96 almond specimens without geographical isolation. These results supported that almonds in Turkey indicated considerable genetic diversity.

In the present study, 14 sugarcane (Saccharum spp. hybrid) genotypes were used for genomic diversity analysis based on nineteen inter simple sequence repeat (ISSR). These nineteen sets of ISSR markers generated a total of 164 discernible and reproducible bands including 109 polymorphic and 55 monomorphic bands. The unweighted pair group method with arithmetic average (UPGMA) analysis revealed three distinct clusters: I, II and III within the 14 genotypes. The polymorphic information content (PIC) value per locus ranged from 0.14 (UBC811) to 0.53 (ISSR1) locus with an average of 0.42 for all loci. The range of genetic distance or coefficient of similarity among sugarcane genotypes varied 0.14 - 0.78. The analysis of these similarities matrix revealed that greater similarity between CoS03234 and CoSe1424 (0.78), and lowest similarity between CoS03234 and Co0118 (0.14). The knowledge gained in this study would be useful to future breeding programs for increasing genetic diversity of sugarcane varieties and cultivars to meet the increasing demand of sugarcane cultivation for sugar and bio energy uses.

Abstract. The aim of this study was to investigate the genetic diversity and structure in three Iranian native goat breeds (Markhoz, Mahabadi and Lori) and the Beetal imported breed using inter-simple sequence repeat (ISSR) markers and also to investigate ISSR markers' potential in order to genetically separate single (S) and twin-birth (T) subpopulations. Blood samples were collected from 210 animals for this purpose. In total, 16 primers were used, and finally 5 primers were selected based on the number of clear bands and the level of polymorphisms. The result of this study showed that 76 of 86 observed fragments were polymorphic. Genetic diversity for each breed ranged from 0.23 in the Beetal breed to 0.26 in the Markhoz breed; this represents a relatively similar genetic diversity in these breeds. An unweighted pair group method with arithmetic mean (UPGMA) dendrogram based on the Nei's standard genetic distance between the breeds studied showed that three Iranian goat breeds (Mahabadi, Lori and Markhoz) were clustered closer together, while the Beetal breed formed a separate cluster. In the constructed dendrogram of the subpopulations, the S and T subpopulations of each breed were clustered together. The constructed dendrogram of the Beetal breed and the S and T subpopulations of all breeds studied showed a separate cluster for the Beetal breed as an imported breed and another cluster for the S and T subpopulations as Iranian native breeds. The current study showed that the ISSR markers studied had no potential to genetically separate S and T subpopulations. On the other hand, these ISSR markers can be used for the clustering of distinct populations.

Forty-three wild lingonberry [Vaccinium vitis-idaea ssp. minus (Lodd) Hult.] clones collected from four Canadian provinces were assessed for genetic variability by using inter simple sequence repeat (ISSR). Fifteen primers generated 356 polymorphic ISSR-PCR bands. A substantial degree of genetic diversity was found am ong the wild collections. Cluster analysis by the unweighted pair-group method with arithmetic averages (UPGMA) separated the wild clones into four main clusters, and identified the two remaining clones as outliers. Furthermore, within four clusters, the genotypes tended to form sub-clusters that were in agreement with the principal coordinate (PCO) analysis. Geographical distribution explained 10% of total variation as revealed by analysis of molecular variance (AMOVA). The ISSR markers detected a sufficient degree of polymorphism to differentiate among lingonberry clones, making this technology valuable for germplasm management and the more efficient choice of parents in current lingonberry breeding programs.

There is widespread confusion and uncertainty concerning the identity of lychee cultivars: the same cultivar may be known under different names and different cultivars may appear under the same name. In the present study, the potential of intersimple sequence repeat (ISSR) for the identification of 66 lychee cultivars and accessions and a determination of their genetic relationships was evaluated, using 32 primers containing different simple sequence repeat motifs. Of the 194 bands produced, 124 (64%) were polymorphic. A set of six ISSR primers was sufficient to distinguish all cultivars and accessions. Thus, cultivars which are morphologically very similar and have identical isozyme profiles can be distinguished by ISSR analysis. However, seven pairs of accessions, each considered to be the same cultivar, were found to be identical by ISSR analysis. Nei and Li band-sharing distances and Nei genetic distances were calculated among the cultivars and two similarity dendrograms were generated using the neighbor-joining algorithm. Results showed that the ISSR technique is a valuable tool for identification of lychee cultivars and analysis of their genetic relationships.
