Abstract. Sunaryo W, Wahida, Idris SD, Pratama AN, Ratanasut K, Nurhasanah. 2020. Genetic relationships among cultivated and wild bananas from East Kalimantan, Indonesia based on ISSR markers. Biodiversitas 21: 824-832. East Kalimantan is one of biodiversity centers for banana in Indonesia including wild or cultivated bananas. This biodiversity is long-historical genetically contributed by the existence of wild cultivars, local/indigenous varieties or introduced accessions from other regions in Indonesia. The existence of cultivated bananas has played an important role in the socio-economic significance of the local people. The genetic contribution of wild and local banana from East Kalimantan to the cultivated bananas or vice versa is very interesting to study. This research reported the genetic relationships among wild and cultivated bananas using Inter Simple Sequence Repeat (ISSR) markers. Thirteen wild and cultivated banana samples collected from different districts of East Kalimantan Province were analyzed using 15 primers of ISSR marker. ISSR primers generated 133 loci, of which 132 were polymorphic (98.98 %) with an average of 9.43 loci per primer. The ISSR marker is very effective and powerful to detect and discriminate the polymorphisms among cultivated and wild bananas. This is supported by PIC value which ranged from 0.60 to 0.91 per primer with an average of 0.80 per primer. The marker index (MI) values were ranged from 1.62 to 11.48 per primer. Primer UBC 855 produced the highest MI value which was 11.48 per primer and UBC 848 resulted in the lowest (1.62 per primer). The similarity coefficients ranged from 0.43 to 0.81. The dendrogram constructed based on UPGMA divided the banana cultivars into 4 clusters, in which the first cluster comprised of the AA/AAA/AB genome bananas (Ambon, Kapas, Tembaga, Liar, and Tanduk). The second cluster composed of only Mauli Banana. The third cluster was comprised of six cultivated banana with AAB or ABB genome i.e., Raja, Rutai, Susu, Kepok, Awak, and Talas banana. The last cluster was only Klutuk Banana (BB genome). Wild bananas (Liar and Klutuk) was the ancestor of cultivated bananas since they contributed for A genome (Musa acuminate) and B genome (Musa balbisiana) to generate many triploid and cultivated bananas. Indigenous banana cultivars from Kalimantan, Rutai is closely related to Susu banana, while Talas banana is related to the AAB genome such as Raja, Rutai, Susu or ABB genome such as Awak and Kepok.

Iran has a rich pistachio germplasm, thereby, the diversity and number of Iranian pistachio cultivars is unique in the world. Genetic diversity is crucial for sustainable use of genetic resources and conservation. As one of the oldest nut crops in human history, pistachio nuts have a high nutritional value and are commercially important. In the present study, the genetic variation of pistachio genotypes was investigated by nuclear ISSR markers. In this study, genetic relationships among 11 cultivars was assessed by using 12 inter simple sequence repeat (ISSR) primers. The total of 53 bands of which 44 (83%) were polymorphic were amplified by the 12 primers, an average of 4.4 bands per primer. The total number of amplified fragments was between 2 to 6 and the number of polymorphic fragments ranged from two to six. The amplified allele sizes ranged from 300 to 1600 bp. Pair-wise genetic similarity coefficients varied from 0.70 to 0.95. The UPGMA dendrogram differentiated the genotypes into two major clusters. The Mantel test showed correlation between genetic and geographical distance. AMOVA revealed a significant genetic difference among cultivars and showed that 35% of total genetic variation was due to within- cultivars diversity. The present results may be used for the conservation, core collection and future breeding of the pistachio.

Multivariate morphometric approach (using PCA mix and CDA) and Inter-Simple Sequence Repeat Markers (ISSR) were used to characterize the patterns of morphological and genetic relationships of Capparis spinosa group in Iran. The morphological data analyses revealed that this complex could be divided into three main groups. C. spinosa subsp. cartilaginea and C. spinosa subsp. spinosa var. mucronifolia were reliably delineated by morphological data, but C. spinosa subsp. spinosa var. parviflora, C. spinosa subsp. spinosa var. herbacea, C. spinosa subsp. spinosa var. canescens, C. spinosa subsp. spinosa var. aegyptia and their intermediate phenotypes were overlapped. The results of ISSR data were different from morphological analyses and var. parviflora exhibited a close genetic affinity to var. mucronifolia rather than the other varieties of sub. spinosa. The results of this study revealed that subsp. cartilaginea should be recognized at species level. In case of var. parviflora, we propose subspecies level for this variety. Further investigation is needed to reveal the taxonomic status of var. mucronifolia.

Mexican sunflower is a native species of North and Central America that was introduced into China early last century, but it has widely naturalized and become a harmful invasive plant in tropical and subtropical regions in South China. Inter-simple sequence repeat (ISSR) markers were employed to assess genetic diversity and variation in Mexican sunflower populations from China and neighboring regions. The karyotypes of populations were also studied. Our research showed high levels of genetic diversity in all populations. The lowest genetic diversity estimates were represented in two populations in Laos, suggesting prevention of new introductions into Laos is critical. Partitioning of genetic variance revealed that genetic variation was mostly found within populations, and unweighted pair group method with arithmetic means (UPGMA) analysis showed that the introductions into China and Laos were independent. There were no obvious correlations between genetic relationships and geographic distance of populations in China, consistent with the human associated dispersal history of Mexican sunflower. Previous cytological data and our chromosome count (2n = 34) and karyotype analysis showed chromosome stability among populations. The high levels of genetic diversity within invasive Mexican sunflower populations could be challenging for its management in China, and further expansion and potential negative effects on ecological systems of this plant should be monitored.

AbstractThe aim of this study is investigation the applicability of SSR and ISSR markers in evaluating the genetic relationships in twenty accessions ofAegilopsandTriticumspecies with D genome in different ploidy levels. Totally, 119 bands and 46 alleles were detected using ten primers for ISSR and SSR markers, respectively. Polymorphism Information Content values for all primers ranged from 0.345 to 0.375 with an average of 0.367 for SSR, and varied from 0.29 to 0.44 with the average 0.37 for ISSR marker. Analysis of molecular variance (AMOVA) revealed that 81% (ISSR) and 84% (SSR) of variability was partitioned among individuals within populations. Comparing the genetic diversity ofAegilopsandTriticumaccessions, based on genetic parameters, shows that genetic variation ofAe. crassaandAe. tauschiispecies are higher than other species, especially in terms of Nei’s gene diversity. Cluster analysis, based on both markers, separated total accessions in three groups. However, classification based on SSR marker data was not conformed to classification according to ISSR marker data. Principal co-ordinate analysis (PCoA) for SSR and ISSR data showed that, the first two components clarified 53.48% and 49.91% of the total variation, respectively. This analysis (PCoA), also, indicated consistent patterns of genetic relationships for ISSR data sets, however, the grouping of accessions was not completely accorded to their own geographical origins. Consequently, a high level of genetic diversity was revealed from the accessions sampled from different eco-geographical regions of Iran.

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. Key words: Morus L., genetic diversity, inter-simple sequence repeat, relatedness

ISSR markers are polymorphic and their results easily reproducible. They are therefore intensely used in phylogenetic studies and sex differentiation of some economically interesting plant species. The objectives of this study were to analyze the genetic diversity in Caricaceae using ISSR markers, to identify a specific ISSR band that could distinguish female from hermaphrodite papaya genotypes and to verify whether this marker could be used for early sex differentiation. The ISSR-PCR was performed with nine primers and they could distinguish all species. It was observed that Jacaratia spinosa was closer to Vasconcellea than to Carica. The species C. papaya was only distantly related to both genera. A 500 bp ISSR marker was found in 25 % of the papaya genotypes studied. Specifically in these cases this marker could be used for early sex differentiation in papaya.

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.
