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.

Among ten slow-growing protoclones of Agaricus bisporus (J. Lge) Imbach, all appressed colonies showed slower growth rate and spawn run, and inability to produce fruiting bodies in substrate. Seven of 40 inter-simple sequence repeat (ISSR) primers amplified 78 reproducible fragments, 48.93% were polymorphic, each producing 7 to 16 bands ranging from 0.10 to 2.10 kbp, sufficient to differentiate the protoclones from each other. Appressed protoclones were homoallelic at a number of loci that were heteroallelic in the parent, suggesting that they represented rare homokaryons. Thus, using morphological characters along with ISSR, polymorphisms could be useful for quick, easy, and accurate in distinguishing homo- and heterokaryotic isolates. Key words: Agaricus bisporus (J.

Inter Simple Sequence Repeat (ISSR) markers are versatile and used in a number of applications viz. genetic diversity estimation, phylogenetic relationship and gene tagging in different crops. In coconut, the ISSR markers are being reported here for the first time. In the present paper, thirty-five  primers targeting to amplify the inter microsatellite  regions were screened  using  thirty  different  coconut  germplasm  accessions.  The  ISSR  primers  were evaluated based on polymorphism information content and marker index.  Out of 35 primers screened,  19 primers  produced  clear amplification  pattern.  The polymorphism  information content varied between 0.019 and 0.386, whereas, the marker index ranged from 0.019 to 5.673  among  the  primers.    Based  on  the  high  marker  index,  five  and  ten  primers  were selected.  The similarity  matrices  were constructed  separately  for five, ten and 19 primers using NYSYS software and the correlation was tested using Mantel’s test. There was high correlation  between five and ten primers with 19 primers. Hence, the primers with higher marker index (5 and 10 primers) were regarded as informative  primers. These informative primers can be used to develop more polymorphic markers in coconut for rapid screening of germplasm materials.

Grapevine cultivars diversity is vast and full of synonyms and homonyms. Up to few decades ago characterization of grapevine was based on morphological characters. In the last decades, molecular markers were developed and have been used as tools to study genetic diversity in a range of different plant species. Fifty-six Portuguese accessions representative of ‘Vinhos Verdes’ and ‘Douro’ Controlled Designations of Origin (DOC) were analysed through DNA fingerprints generated by Random Amplified Polymorphic DNA (RAPD) and Inter Simple Sequence Repeat (ISSR). The study aimed to compare the effectiveness of RAPD and ISSR molecular techniques in the detection of synonyms, homonyms and misnames. RAPD and ISSR analysis enabled the detection of 36 different band patterns, reducing in about 36% the initial material. Several accessions grown under different names, between and within collections, were confirmed as the same genotype, namely Gouveio/Verdelho, Sousão Douro/Vinhão and Arinto Oeste/Pedernã. Similarly, some homonyms/misnames were also identified, namely within Azal Tinto and Rabigato accessions. RAPD and ISSR markers revealed to be adequate molecular techniques for grapevine varieties fingerprinting with advantages over other molecular procedures, contributing for a good management of grapevine collections.

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.

Aerva javanica is one of Egypt’s most important traditional medicinal plants used as antidiarrheal and anthelmintic medicine and recently as an anticancer agent. In this study, variations among ten populations of Aerva javanica in different sites in the Eastern Desert of Egypt were analyzed based on morphological and ecological attributes and molecular variation expressed by Inter-Simple Sequence Repeat (ISSR) markers. Morphological diversity was higher for populations in the Wadi El-Markh and Bir Abbady regions than others. The polymorphism revealed by ten ISSR primers was 79.4% among populations. Distance trees created using the results obtained from soil variables, morphological characterizations, and molecular data showed that the highest similarity was 0.974 between Populations 8 and 9, while the lowest similarity was 0.715 between Population 1 and Population 3 regions. In conclusion, the obtained data are important to design a plan for sustainable conservation of Aerva javanica as an important medicinal plant having a wide interspecific genetic variability within various populations.

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.

Abstract Mulberry (Morus spp.) is a cross-pollinating and highly hybridized plant of which productivity are greatly varied in different varieties. We analysed molecular distinction among four mulberry species and varieties cultivated in DPR Korea by using nuclear ribosomal internal transcribed spacer (ITS) sequences and inter simple sequence repeat (ISSR) markers. ITS sequences didn’t represent a remarkable interspecific distinction among four mulberry species used in our study, suggesting that it could not be employed to identify them. ISSR analysis using 16 random primers generated 158 different markers ranging from 100 to 4000 bp in size. The results showed the inter-specific genetic variation (55.34%) was slightly higher than intra-specific genetic variation(44.66%), with comparatively low average number of migrants per generation (Nm) among populations (0.3886). Using ISSR primers selected in this study, in the future, the suitable breeding strategy might be established in raising of elite mulberry varieties on the basis of interspecific hybridization.
