The inter-simple DNA sequence repeat (ISSR) method was used to study genetic diversity in three local cattle from the north, northeast and north west of Tunisia. Twenty samples were analysed using three ISSR primers. In total, 22 bands were amplified of which 15 are polymorphic (68.18%). The total genetic diversity (Ht), genetic diversity within populations (Hs), coefficient of gene differentiation (Gst) and gene flow (Nm) were 0.2706, 0.01314, 0.8841 and 0.0656. To better visualize the structure of the population, a UPGMA dendrogram constructed from the genetic distances of NEI shows that the populations of North (Bizerte) and Northeast (Nabeul) are genetically closest while that of Northwest (Jendouba and Siliana) is the furthest from the two others.

The utility of intersimple sequence repeat (ISSR) markers for identification of English or Persian walnut (Juglans regia L.) cultivars was explored. Four cultivars were screened with 47 ISSR primers; eight of these primers, which generated reproducible and informative data, were selected for further study. Two individuals from each of 48 cultivars, including many currently important in the California walnut industry as well as accessions from Europe and Asia, were then examined with the eight ISSR primers. Polymerase chain reaction (PCR) products were separated on agarose gels and stained with ethidium bromide. Fifty-four bands were scored as present or absent in each cultivar; of these, 31 (57%) were polymorphic among the 48 cultivars. Combined data from the eight ISSR primers provided a unique fingerprint for each of the cultivars tested. Fifteen of the cultivars could be distinguished from all others with just one primer, 31 with a minimum of two primers, and two required three primers. Pairwise genetic distances between the cultivars were calculated and a dendrogram was generated using the neighbor-joining algorithm. Some of the groupings in the dendrogram corresponded to groups which, based on known pedigrees, are genealogically closely related. Others included accessions from diverse genetic and/or geographic origins. These results can be attributed to a combination of the limitations of the ISSR method for inferring genetic relationships, on the one hand, and the complex history of walnut cultivar development involving extensive exchange and breeding of germplasm from different geographic regions, on the other.

Within the present study, it was conducted a genetic diversity analysis using ISSR markers for some apple genotypes grown in Ardahan region, Turkey. Total genomic DNA (gDNA) isolation from apple leaves was performed using commercial kits. Five ISSR primers were used to determine the genetic diversity among the genotypes studied. Polymerase Chain Reaction (PCR) was performed with all gDNA samples to produce bands to score. PCR products were run in agarose gel and visualized under UV light. Bands on the gels were scored as “1”, while no bands at the corresponding positions were scored as “0”, to generate the matrix file. Five ISSR primers produced a total of 35 bands, and 20 of them were polymorphic. The polymorphic bands rated approximately 57%. Phylogenetic relationships and genetic distances between the genotypes were calculated by using the PAUP [Phylogenetic Analysis Using Parsimony (and Other Methods)] program.  According to the PAUP data, the closest genetic distance was 0.03704 between ‘Kaburga’ and ‘Japon Apple’ genotypes, while the furthest genetic distance was 0.48148 between ‘Karanfil Apple’ and ‘Sisli Uruset’. The phylogenetic analysis obtained using UPGMA algorithm produced a phylogenetic tree with two clades. The results suggest that ISSR markers are useful tools for determining genetic relationships among apple genotypes.

Tomato is one of the most economically important vegetable crops in many parts of the world. Turkey and Iran are the main producers of tomatoes in the world. The objective of this study was to assess the genetic variation of 93 tomato landraces from East Anatolian region of Turkey and North-West of Iran, along with three commercial cultivars using 14 ISSR primers. The percentage of polymorphic loci (PPL) for all primers was 100%. The mean of expected heterozygosity (He) for the primers varied from 0.153 (UBC808) to 0.30 (UBC848). The dendrogram placed the landraces and commercial cultivars into nine groups. The genotypes originating from the same region, often located in the same group or two adjacent groups. The highest likelihood of the data was obtained when population were located into 2 sub-populations (K = 2). These sub-populations had Fst value of 0.16 and 0.21.

Five species of Trifolium L. (T. repens L., T. pretense L., T. hybridum L., T. campestre Schreb., and T. dubium Sibth.) were analyzed used to evaluate the genetic diversity and their phenetic relationships using inter-simple sequence repeats (ISSR) markers. Overall, T. pratense exhibited higher variation than other species. 114 amplicons were produced by ISSR markers, of which 77 (67.5%) bands were polymorphic. T. dubium showed the low genetic variation. Total genetic diversity values (HT) varied between 0.333 and 0.487, for an average over all polymorphic loci of 0.282. On a perlocus basis, the proportion of total genetic variation due to differences among species (GST) was 0.380. This indicated that about 38.0% of the total variation was among species. The estimate of gene flow, based on GST, was very low among species of genus Trifolium (Nm = 0.816). An assessment of the proportion of diversity present within species, HPOP/HSP, indicated that about 95.8% the total genetic diversity was within species. T. pratense and T. hybridum were grouped together and this clade was sister with T. repens. Two remainder species with yellow flowers were grouped together. Information on genetic diversity for Trifolium is valued for the management of germplasm and for evolving conservation strategies.Bangladesh J. Plant Taxon. 23(2): 167-173, 2016 (December)

Randomly amplified polymorphic DNA (RAPD) and inter simple sequence repeat (ISSR) markers were used to investigate genetic variability within thirteen Viburnum species (Viburnum × hillieri; V. dilatatum; Viburnum × carlcephalum; V. opulus; V. hupehense; Viburnum× bodnantense; Viburnum × burkwoodii; V. sieboldii; Viburnum × globosum ‘Jermyns Globe’; V. alnifolium (lantanoides); V. plicatum ‘Sterile’; V. plicatum f. tomentosum and V. plicatum ‘Watanabe’) of wide geographical distribution, collected in the Dendrological Garden in Przelewice (the north-west part of Poland). Twenty-three RAPD and fourteen ISSR primers generated a total of 690 and 418 reproducible bands, respectively, and 39% (RAPD) and 55.5% (ISSR) of them were polymorphic for the two marker systems, which suggest high genetic variability within Viburnum genus. However, high numbers of genotype-specific bands, i.e. 60.9% (RAPD) and 44.5% (ISSR), were seen in Viburnum. Genetic similarity assessed within Viburnum species with the RAPD and ISSR analyses ranged from 6 to 42% and from 6 to 31%, respectively. Both RAPD and ISSR-based dendrograms clustered in five main groups. The Mantel test between two Nei’s similarity matrices gave correlation coefficient r=0.305*, showing low correlation between RAPD- and ISSR- based matrices. Thus, both marker systems were equally important for the genetic diversity analysis in Viburnum genus.

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.

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.

The two main secondary metabolites in Glycyrrhiza Species are Glycyrrhizic acid and liquiritin. They are considered as active ingredients . The content of these compounds showed variation in different species. Standard chemical fingerprints were generated from cultivated Glycyrrhiza uralensis, G. inflate and G. glabra, which could be identification markers. Five efficient inter-simple sequence repeat (ISSR) primers were screened and optimized for detecting the genetic diversity in three cultivated Glycyrrhiza uralensis, G. inflate and G. glabra. By using two characteristic peaks compare with three cultivars, Glycyrrhiza uralensis and G. glabra were bigger similarity than G. inflate. The results is in accordance with the results by ISSR markers. The higher genetic diversity in G. inflate was useful to more broad breeding. Our result suggest that provides an optimized method for assessment genetic diversity of cultivated Glycyrrhiza uralensis, G. inflate and G. glabra using Chemical fingerprint and ISSR markers which is useful for further investigation in breeding.
