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.

In this study, Rosa × ozcelikii Korkmaz & Kandemir is described as a new natural hybrid between Rosa villosa subsp. mollis and R. hemisphaerica from material collected in Erzincan province (Turkey). It was compared with closely related species using morphological data. In addition, genetic relationships of the new hybrid with the putative parental taxa were determined by Random Amplified Polymorphic DNA (RAPD) and Inter Simple Sequence Repeat (ISSR) markers. Properties of soils in which the new hybrid grows in the wild are also presented.

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.

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.

One hundred and twenty Spanish landraces of peas (Pisum sativum L.) collected in different micro-climatic areas, together with three commercial varieties and one breeding line, were subjected to molecular characterization using Inter Simple Sequence Repeat (ISSR) amplification. Landraces originated from 7 to 1427 m asl. Most accessions were collected in temperate areas with dry Mediterranean humidity regimes. ISSR markers detected high levels of variability between accessions and were useful for identification of individuals and clarification of genetic relationships between them. The 18 groups obtained with molecular data were not significantly related to 21 agro/climatic regions. Clustering based on climatic and ISSR characters differed because the data types present different aspects of genetic diversity. These results will be applied to establish a pea core collection at the Plant Genetic Resources Centre of the Spanish National Institute of Agriculture and Food Research and Technology (CRF-INIA).

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.

Abstract Morinda (Rubiaceae) is considerably recognized for its multiple uses viz. food, medicine, dyes, firewood, tools, oil, bio-sorbent etc. The molecular characterization of such an important plant would be very useful for its multifarious enhanced utilization. In the present study, 31 Morinda genotypes belonging to two different species Morinda citrifolia and Morinda tomentosa collected from different regions of India were investigated using Inter Simple Sequence Repeat (ISSR) markers. Fifteen ISSR primers generated 176 bands with an average of 11.7 bands per primer, of which (90.34%) were polymorphic. The percentage of polymorphic bands, mean Nei’s gene diversity, mean Shannon’s information index in Morinda tomentosa and Morinda citrifolia was [(69.89%, 30.68%); (0.21 ± 0.19, 0.12 ± 0.20); (0.32 ± 0.27 0.17 ± 0.28)] respectively, revealing higher polymorphism and genetic diversity in Morinda tomentosa compared to Morinda citrifolia. Structure, and UPGMA cluster analysis placed the genotypes into well-defined separate clusters belonging to two species Morinda tomentosa and Morinda citrifolia revealing the utility of ISSR markers in species differentiation. Distinct ecotypes within a particular species could also be inferred emphasizing the collection and conservation of Morinda genotypes from different regions, in order to capture the overall diversity of respective species. Further higher diversity of M. tomentosa must be advanced for its utilization in nutraceutical, nutritional and other nonfood purposes.
